Metal Polymer Bearing

The metal-polymer bearing suitable for dry running with a low coefficient of friction, low wear rate, good sliding characteristics, These self-lubricating bearings. They can be used with a rotational, oscillatory, and axial sliding motion.

In order to assure long-life span and superior quality, all PTFE bushings for valves.valves are moulded from pure, virgin PTFE material. Virgin PTFE provides for an excellent chemical resistance and can be used with aggressive media. Typical characteristics of fluoropolymer resins include chemical inertness, exceptional dielectric properties, toughness and flexibility, low coefficient of friction, negligible water absorption and non-stick characteristics. All these properties provide increased protection against permeation of the line media. Further, low coefficient of friction reduces valve operation torque.

The self-lubricating bearings and washers that are specially manufactured with a bonding of a filled PTFE coated fabric on various baking metal layers like: carbonsteel, bronze, stainless steel and Carbon steel. The sliding surface is primarily composed of a filled PTFE coated fabric and other elements toguarantee the highest wear resistance. The stainless steel bushing products find their best usage in slow-movingapplications.

• Excellent corrosion and wear resistance
• Resistance of chemicals including dilute acids and alkalis, petroleum solvents, alcohols, greases and oils
• Resistance to humidity & water
• Resistance to ultra - violet radiation
• Excellent resistance to abrasion
• Impact resistance without chipping or cracking

This ASTM A240 TYPE 316 WITH PTFE COATED BEARING product has a high wear resistance and can work in dirty or abrasive environment.

High-Performance Butterfly Valves -  stainless steel bushing

Stainless Steel Bushing is wrapped by steel backing, Sinter bronze layer and PTFE antiwar surface.

As a market leader in ASTM A240 TYPE 316 WITH PTFE COATED BEARING products, Viiplus stocks a wide variety of metals, grades, shapes, and specifications. Whether shopping for commercial or valve bushing, you can be assured to find a wide range of sizes and assortment of grades.

Stainless steel bearing is a special type DU bushing. It takes stainless steel as base material, sintered bronze as middle layer and PTFE as sliding layer. This type self lubricating bearing is also called SS bearing, SS DU bushing, SS DU bearing.

Self-Lubricating Multilayer Composite Bushing

Its material structure is Steel base + Bronze powder + PTFE and filler. It can offer the good properties of self-lubricating, anti-abrasion, low-friction, fully developing the advantages of metal and multi-element polymer. It’s applied to the printing, woven, tobacco and gymnastic machinery, etc.

316/316L steel has outstanding corrosion resistant properties, whether it is atmospheric or oxidizing environment, even for marine atmosphere, it shows excellent corrosion resistance in welded state. Normally 316/316l steel shows no magnetic in annealed condition, cold drawn or cold rolling process may make it with little magnetic, and it can be fixed with further processing.

Applications of ASTM A240 316/316L

316/316L plate is used to manufacture products for applications that are exposed to salt water, acids such as sulfuric acid and chloride, petrochemicals and chemicals and high-heat such as engines and motors.Products include tanks, supports and frames, enclosures and housings, engine, motor and machinery components and parts.

The valve is used to open and close the pipeline, control the flow direction, adjust and control the parameters of the conveying medium (temperature, pressure, and flow) pipeline accessories. According to its function, it can be divided into shutoff valve, check valve, regulating valve, etc. The valve is the control part in the fluid conveying system, which has the functions of cut-off, regulation, flow diversion, countercurrent prevention, pressure stabilization, diversion or overflow relief. Valves for fluid control systems range from the simplest globe valves to those used in the most complex automatic control systems. Valves can be used to control the flow of air, water, steam, corrosive media, mud, oil, liquid metal and radioactive media, and other types of fluid. Valves according to the material is also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chromium-molybdenum steel valves, chromium-molybdenum vanadium steel valves, double-phase steel valves, plastic valves, non-standard customized valves.

FAQ:

Q: Are bearings used in oil and gas production?

A: We understand the key issues in the oil and gas industries, and offer bearing solutions that provide the performance and durability they demand. Our self-lubricating bearing materials resist wear, chemicals, cavitation, flow erosion and fatigue, making them ideal for a wide range of applications in oil and gas operations.

Q: Which type of bearings can be used in radial or axial piston pumps?

A: Radial and axial piston pumps are used primarily in construction, agriculture, automotive, material handling and industrial equipment. Both use shaft journal bearings to support their loads and speeds.
 

Q: What is your terms of packing?
A: Generally, we pack our goods in neutral cartons. If you have legally registered patent, we can pack the goods in your branded boxes after getting your authorization letters.
