Seven principles should be followed in the selection of oil-free bearing lubricants:   1. Environmental conditions. When the bearing is in the wet, corrosive gas, low temperature, dust, strong radiation conditions, the lubricating oil is easy to be polluted deterioration, then should choose water resistance, wear resistance, corrosion resistance, cold resistance, radiation resistance lubricating oil. Splash in the water, emulsion injection, humid air or dust dust in the serious place, generally should not choose lubricating oil, but should choose grease.   2. Bearing accuracy. The friction surface of bearing movement is rough, which is generally suitable for lubricating oil with large viscosity. In order to bear the local pressure caused by bad contact, the friction surface with high precision should be selected with low viscosity to reduce frictionLess unnecessary energy loss and temperature rise.   3. Operating temperature. Operating temperature affects the viscosity and lubricating effect of lubricating oil. Therefore, when the working temperature is low, should choose the lower viscosity of the lubricating oil; When the operating temperature is very high, should choose high viscosity or suitable additives. When higher than, you can generally consider using a solid lubricant. Ambient temperature is different, the choice of lubricating oil viscosity should also be changed, such as the same lubrication bearings, in north China or winter, should choose viscosity less than the south or summer lubricating oil. When the operating temperature changes frequently, it is also necessary to choose the temperature characteristics of the good viscosity lubricating oil, that is, the viscosity of the lubricating oil will not change when the operating temperature increases or decreases, to ensure that the thickness of the oil film is stable within a certain range.   Without oil bearing 4. Speed movement. The higher the rotation speed, the lower the viscosity should be selected to avoid the increase in motion resistance, heat Too much; On the contrary, at low speed, high viscosity lubricants should be used to improve the bearing capacity.   5. The nature of sports. There are impact, vibration, constant load change, variable speed, starting. Stop, frequent inversion, and do reciprocating or intermittent movement, are not conducive to the formation of oil film, should choose higher viscosity lubricating oil. Grease, even solid lubricants, are sometimes preferred to ensure reliable lubrication.   6. Workload. The greater the load borne by the rolling bearing, the higher the viscosity of the lubricating oil shall be, and shall have a good lubricating oil and extreme pressure, so as not to squeeze the lubricating oil from the friction pair, or to make direct contact with the metal. Structural features. The smaller the radial clearance of rolling bearing is, the higher the processing precision of friction surface is, and the lower the viscosity of lubricating oil should be.   7. Bearing hardness. Bearing friction surface hardness is low, should choose high viscosity lubricating oil, and the amount of oil to be sufficient; Conversely, can reduce the viscosity of lubricating oil. 24/7 Online Support VIIPLUS is always here to support your business.

  Hydraulic systems are suitable for hydraulic systems mainly because of their system disassembly difficulties and maintenance-free requirements which are important for their system characteristics.   High seal, friction resistant bearing sleeve  It is a new kind of material designed on the basis of vsb-1p Hydraulic bearing combined with the working principle of oil cylinder and shock absorber. It is more wear-resisting under the condition of no oil. In addition to the advantages of vsb-1p, the product is especially suitable for the occasion of reciprocating frequent large trend force.Its performance is similar to that of foreign DP4. At present, this product gradually replaces vsb-1p product, which is suitable for automobile, motorcycle shock absorber and various hydraulic cylinders and other fields.   Bearing application     Hydraulic components and valves: gear pumps, plunger pumps, vane pumps, ball valves, butterfly valves, cylinders, cylinders and other hydraulic components;   Chemical properties The surface polymer of VSB-2 Hydraulic bearing sleeve is resistant to chemical corrosion, so its corrosion resistance mainly depends on the steel back and exterior electrodeposit.Copper or tin plating on steel back surface can effectively prevent atmospheric corrosion;If working in corrosive medium, steel back can be galvanized, etc.             The main factors affecting the bearing sleeve life 1) the influence of PV value, which is an effective indicator to determine the wear life of chb-1.If life extension is required, the PV value must be reduced. 2) the influence of ambient temperature. The higher the ambient temperature, the shorter the service life of chb-1.3) the impact of dual parts The service life of chb-1 bearing can be significantly improved when the dual part adopts alloy steel or hard chromium plated shaft, and the surface roughness Ra=0.4~0.63 range.In addition to the standard products shown in the catalog non-standard products can be provided or ordered upon customer request.   Operating characteristics of hydraulic bearing     Phase 1 the surface layer PTFE mixture is transferred to the dual surface to fill the pits in the dual surface and form the transfer film. Phase 2 After running, the friction becomes the friction between PTFE, the friction coefficient is low and stable, and the wear rate of the material is low and stable Phase 3 The consumption of PTFE lubricant in the pores of the porous layer makes it impossible to obtain enough lubricant between the friction interfaces.With poor lubrication between friction surfaces, the friction coefficient rises rapidly, and the wear rate of the material accelerates rapidly, until 70% of the bronze is exposed, the hydraulic bearing life is close to the end.    

  Large size bearing sleeve is generally used in logistics ports, because the field of machinery generally requires high bearing capacity, high hardness, long life and other design requirements.   High strength, high wear, maintenance-free bearing     For example, the VSB-JDB-1 solid inlaid bearing is on a matrix of colliers brass.A high performance solid lubricant with graphite or MoS2 solid lubricants. It breaks through the general bearing lubrication by oil film limitations.In the process of use, through the friction heat to make the solid lubrication and shaft friction, the formation of oil, powder co-lubrication excellent conditions, not only protect the shaft from wear, and make the solid lubrication characteristics eternal.Its hardness is higher than general copper sleeve one times wear-resisting performance is also one times suitable for port machinery and other use requirements.     Improve reliability and work efficiency   It is well known that the port equipment part is used near the water source, environmental protection, high corrosion resistance and other requirements are also higher than the general mechanical parts requirements. and on time.   Environmental protection bearing sleeve Lead-free bearing is a new product developed based on VSB-1x materials according to international environmental protection requirements .The product is widely applicable to general machinery, food machinery  pharmaceutical machinery, tobacco machinery in particular, lead-free effect  in line with the European environmental protection require.   Low noise, high lubrication bearing sleeve Oil-free lubricated bearing is a plain bearing made of steel plate matrix, spherical bronze powder sintered in the middle, and a mixture of PTFE and lead rolled on the surface.It has the characteristics of small friction coefficient, good wear resistance, corrosion resistance and oil-free lubrication.

The Vital Role of Hydraulic Sliding Bearings in the Oil & Gas Industry: A Deep Dive into Performance and Applications In the high-stakes world of oil and gas, where equipment reliability can make or break operations, hydraulic sliding bearings stand out as unsung heroes. These precision-engineered components, particularly graphite bronze bushings and cast bronze bearings, are critical to the performance of hydraulic systems, pumps, and valves used in energy extraction and processing. This blog post explores the pivotal role of hydraulic sliding bearings, their applications in the oil and gas sector, and why they are indispensable for ensuring operational efficiency and durability. We’ll dive deep into their technical advantages, use charts and tables for clarity, and contrast their benefits with alternative solutions to provide a comprehensive understanding. What Are Hydraulic Sliding Bearings? Hydraulic sliding bearings are specialized components designed to reduce friction and wear in moving parts under heavy loads, high pressures, or corrosive environments. Unlike rolling-element bearings (e.g., ball or roller bearings), sliding bearings rely on a sliding interface, often lubricated by a fluid film or self-lubricating materials like graphite. In the oil and gas industry, graphite bronze bushings and cast bronze bearings are widely used due to their durability, corrosion resistance, and ability to perform in demanding conditions. Key Features of Hydraulic Sliding Bearings Self-Lubrication: Graphite-embedded bronze bearings provide continuous lubrication, reducing maintenance needs. Corrosion Resistance: Bronze alloys withstand harsh chemicals and saline environments common in oil and gas operations. High Load Capacity: Capable of supporting heavy loads in high-pressure systems like piston pumps. Versatility: Used in valve stems, pump shafts, wear plates, and marine hardware. Applications in the Oil & Gas Industry Hydraulic sliding bearings are integral to a wide range of equipment in the oil and gas sector, particularly in pumps and valve actuation systems. Let’s explore their primary applications and why they matter. 1. Hydraulic Pumps Hydraulic pumps, such as gear pumps, vane pumps, and piston pumps, rely on sliding bearings to ensure smooth operation under extreme pressures. For instance, high-pressure piston pumps, which are critical in drilling and fracturing operations, demand bearings that can handle intense mechanical stress and corrosion from drilling fluids. Case Study Insight: VIIPLUS, a leading manufacturer of graphite bronze bushings, has been praised for advancing China’s hydraulic piston pump industry. Their bearings have enabled pumps to operate reliably at pressures exceeding 40 MPa (megapascals), a testament to their engineering precision. 2. Valve Actuation Valves in oil and gas systems control the flow of crude oil, natural gas, and other fluids. Sliding bearings, such as PTFE-lined bronze bearings and graphite bronze bushings, ensure precise movement of valve stems and actuators, even in corrosive or high-temperature environments. Example: In offshore platforms, where valves are exposed to seawater and high humidity, corrosion-resistant bronze bearings extend equipment lifespan by up to 30% compared to steel-based alternatives. 3. Other Applications Shafts and Pump Shafts: Bearings reduce wear and vibration, improving energy efficiency. Wear Plates: Used in heavy machinery to protect surfaces from abrasion. Marine Hardware: Bronze bearings resist saltwater corrosion, making them ideal for subsea equipment. Why Choose Hydraulic Sliding Bearings? A Comparative Analysis To understand the value of hydraulic sliding bearings, let’s compare them with rolling-element bearings and polymer-based bearings commonly used in similar applications. Table 1: Hydraulic Sliding Bearings vs. Alternatives Feature Hydraulic Sliding Bearings (Bronze) Rolling-Element Bearings Polymer Bearings Load Capacity High (up to 50 MPa) Moderate (10-20 MPa) Low (5-10 MPa) Corrosion Resistance Excellent (bronze alloys) Poor (steel-based) Good (depends on type) Self-Lubrication Yes (graphite-embedded) No (requires external lube) Yes (some types) Maintenance Needs Low High Moderate Temperature Range -40°C to 300°C -20°C to 150°C -50°C to 200°C Cost Moderate to High High Low to Moderate Best Use Case High-pressure, corrosive environments High-speed, low-load Low-load, lightweight   Contrasting Logic Sliding vs. Rolling Bearings: Rolling-element bearings excel in high-speed applications but falter in high-load, corrosive environments due to their steel construction and reliance on external lubrication. Sliding bearings, with their self-lubricating properties and bronze alloys, are better suited for the oil and gas industry’s harsh conditions. Sliding vs. Polymer Bearings: Polymer bearings are lightweight and cost-effective but lack the load-bearing capacity and durability of bronze bearings. For high-pressure piston pumps or valve actuators, polymer bearings risk deformation or failure. Technical Advantages of Graphite Bronze Bushings Graphite bronze bushings, such as those produced by VIIPLUS, offer unique advantages that make them a preferred choice in oil and gas applications. Here’s a deeper look: 1. Self-Lubrication Mechanism Graphite particles embedded in the bronze matrix release lubricating films during operation, reducing friction even in dry or low-lubrication conditions. This is critical in subsea or remote operations where maintenance is challenging. Chart 1: Friction Coefficient Comparison markdown | Bearing Type | Friction Coefficient (μ) | |------------------------|--------------------------| | Graphite Bronze Bushing | 0.05-0.10 | | Steel Bushing | 0.15-0.25 | | Polymer Bushing | 0.10-0.20 | Insight: Graphite bronze bushings maintain a lower friction coefficient, reducing energy loss and wear. 2. High Load and Pressure Tolerance Bronze bearings can withstand pressures up to 50 MPa, making them ideal for high-pressure hydraulic systems. Their robust construction ensures minimal deformation under load. 3. Corrosion Resistance Bronze alloys, often combined with tin or aluminum, resist corrosion from saltwater, acidic fluids, and high humidity. This is particularly valuable in offshore drilling and refining operations. 4. Customizability Manufacturers like VIIPLUS offer custom-machined bearings tailored to specific dimensions, tolerances, and groove designs (e.g., spiral or linear grooves for enhanced lubrication). Challenges and Considerations While hydraulic sliding bearings offer significant benefits, there are challenges to consider: Initial Cost: Bronze bearings are more expensive than polymer alternatives, though their longevity often offsets the cost. Installation Precision: Improper installation can lead to misalignment, increasing wear. Material Selection: Not all bronze alloys are suitable for every application; careful selection is needed based on fluid type and operating conditions. Mitigation Strategies Work with reputable suppliers who provide material certifications and technical support. Use advanced machining techniques to ensure precise fit and alignment. Conduct regular inspections to monitor bearing performance in critical applications. The Future of Hydraulic Sliding Bearings in Oil & Gas As the oil and gas industry evolves, hydraulic sliding bearings are poised to play an even larger role. Emerging trends include: Advanced Materials: Development of composite bronze alloys with enhanced wear resistance. Smart Bearings: Integration of sensors to monitor temperature, load, and wear in real-time. Sustainability: Focus on recyclable materials and reduced lubrication needs to align with environmental regulations. Conclusion Hydraulic sliding bearings, particularly graphite bronze bushings and cast bronze bearings, are indispensable in the oil and gas industry. Their ability to withstand high loads, resist corrosion, and operate with minimal maintenance makes them ideal for hydraulic pumps, valve actuation, and other critical applications. By choosing high-quality bearings from trusted manufacturers like VIIPLUS, operators can enhance equipment reliability, reduce downtime, and improve operational efficiency. For those in the oil and gas sector, investing in hydraulic sliding bearings is not just a technical decision—it’s a strategic one that drives long-term success. Whether you’re managing offshore rigs or onshore refineries, these components are the backbone of your equipment’s performance.

Cast Bronze Bushing Manufacture Today CAST BRONZE PLUGGED GRAPHITEBUSHING PRODUCTION PROCESS(OD≤120MM) CAST BRONZE PLUGGED GRAPHITEBUSHING PRODUCTION PROCESS(OD＞120MM) Material Production process,bronze graphite bearings casting process cast bronze graphite plugged oiles bearing provide a maintenance free bearing solution, particularly for high load, intermittent of oscillating motion.Graphite plugged oiles bearing is made of cast bronze alloy base material with special solid lubricants plugged. The base metal withstands high load and the graphite provide self-lubrication. This type of oiles bearing shows excellent performance without pre-lubrication under conditions of extreme high/low temperature with low speed. -Continuous Casting Continuous casting is an advanced method of casting in which molten metal is continuously poured into a special metal mold called a mold. The solidified (encased) casting is continuously pulled out from the other end of the mold.The development of continuous casting is an important means to optimize the structure of China's metallurgical industry, which will fundamentally change the low efficiency and high consumption of China's metal material production, and promote the development of product structure to the direction of specialization.The development of advanced continuous casting technologies, such as near-final continuous casting, single crystal continuous casting, high-efficiency continuous casting and hot charging of continuous casting billet, will be very active, and will promote the development of a series of new materials. -Centrifugal Casting Centrifugal casting is a technique and method of pouring liquid metal into a rapidly rotating mold to fill the mold and form a casting.Because of the centrifugal motion, the liquid metal can fill the mold well in the radial direction and form the free surface of the casting.Cylindrical inner hole can be obtained without core.Helps to remove gases and inclusions from liquid metals.Affect the crystallization process of metal, thus improving the mechanical and physical properties of castings.

The basic principle of Cast bronze bearings is a high performance solid lubrication product with graphite and MoS2 composite solid lubricants embedded in a metal matrix. It breaks through the general bearing lubrication by oil film limitations. In the process of use, through the friction heat to make the solid lubricant and the shaft friction, the formation of oil, powder coexistence lubrication excellent conditions, not only the preservation of the guard shaft does not wear, and make the solid lubrication characteristics eternal. Its hardness is higher than average copper sleeve one times, wear-resisting property is also one times. At present, it has been widely used in metallurgy continuous casting machine, train support, steel rolling equipment, mining machinery, ships, gas turbines and other high temperature, high load, low speed heavy load and other occasions.     First, we introduce the two most common types of casting process for copper sleeve bearing. They are sand casting, centrifugal casting and continuous casting. (1) centrifugal casting: it is a casting method of solidifying by pouring metal liquid into the rotating mold and filling the mold with centrifugal force. Process flow: process characteristics advantages: 1. There is almost no metal consumption of pouring system and riser system, so as to improve process output rate; 2. 2. Hollow castings can be produced without core, so the metal filling capacity can be greatly improved in the production of long tubular castings; 3. High casting density, few defects such as porosity and slag inclusion, and high mechanical properties; 4. It is convenient to manufacture composite metal castings of cylinder and sleeve. Disadvantages: 1. There are certain limitations in the production of special-shaped castings; 2. The casting inner hole diameter is inaccurate, the surface of the inner hole is rough, the quality is poor, and the machining allowance is large; 3. Casting is easy to produce specific gravity segregation. Application: centrifugal casting was first used in the production of cast pipes. Centrifugal casting technology is used in metallurgy, mining, transportation, irrigation and drainage machinery, aviation, national defense, automobile and other industries at home and abroad to produce steel, iron and non-iron carbon alloy castings. Among them, centrifugal cast iron pipe, internal-combustion engine cylinder liner and axle sleeve are the most popular castings.   Continuous casting: an advanced method of casting in which molten metal is continuously poured into a special metal mold called a mold. A solidified (encased) casting is continuously pulled out of the mold to obtain a casting of any length or a specific length. 1. Because the metal is cooled rapidly, the crystal is dense, the structure is uniform, and the mechanical properties are good; 2. Save metal and increase yield; 3, simplify the process, eliminate the modeling and other processes, thus reducing the labor intensity; The production area required is also greatly reduced; 4, continuous casting production is easy to achieve mechanization and automation, improve production efficiency. Application: the continuous casting method can be used to cast steel, iron, copper alloy, aluminum alloy, magnesium alloy and other long castings with the same section shape, such as ingot, slab, bar, tube, etc.     The best way to determine which casting method is best for your project is to consult one of our experienced sales engineers. They will study each factor relevant to your project and recommend casting methods for copper sleeves, axles, and components for your individual needs.
