Types of Plain Bearings (Bushings)
A plain bearing, also known as a bushing, is a mechanical element used to reduce the friction between rotating shafts and stationary support elements. Typically, a bushing relies on soft metal or plastic and an oil film to support the rotating shaft on the hardened journal. Plain bearings are mainly used in machines that have a rotating or sliding shaft component.Also called pillow block bearings, plain bearings or plain bearings, plain bearings do not have rolling elements. Some are made of relatively soft metal, such as Babbit, to protect the shaft necks. They are also made from other materials, depending on the application and load requirements. Other bushings can be used for leveling devices in drilling operations.
Bushing Material Types
Material choice for plain bearings is far greater than for ball and roller bearings owing to the need to find material that can support self-lubricating bearings parts, provide bases that are softer than shaft journals, provide plain bearing composite material, etc. Load and speeds play a big role in determining materials, as do environmental conditions. Dry-running plastic bushings are favored in pharmaceutical and food packaging where oil and metal are considered potentially harmful if they can contaminate the products. Stainless Steel Backed Lubricated Bushing can sometimes be used in marine applications where ptfe fabric layer serves as a lubricant . Stainless Steel Bushings Kevlar Liner Material Strips TEX PTFE Fiberglass Lined is the traditional material for hydrodynamic bearings used in turbomachines. Materials for sleeve bearings are often composed of alloys of steel backed bronze bushing, which satisfy the various requirements of lubrication and resiliency.

Stainless steel fabric bushings,this kind of bushings widely used in valve,oil, chemistry, metallurgy.It has flexible bearings, no maintenance, low installation accuracy, good shock absorption and impact resistance. Low noise characteristics, and due to the high strength of the fiber material and the support of the steel back, it has the unique advantage of high load capacity. In general sports, it is advisable to maintain proper clearance between the inner hole and the shaft. The size of the gap can be referred to the DU type product. The outer diameter of the bearing and the seat hole are generally interference fit. The interference can also be referred to the DU type product.
Metal matrix fabric composite sheet has more flexibility than general rigid bearings due to the 0.25mm thickness of fiber cloth lubrication layer. In some low-speed rocking motions, the bearing inner hole and the pin shaft can be used without gaps or even interference. Cooperate, this can better exert its shock absorption and low noise performance; such bearings are mainly used in low-speed, heavy-duty oil and grease lubrication, and can also be used in oil-free lubrication.

TEX bearing use the PTFE fibres fabric and aramid fiber overlay on metal backings,the fabric have very high load capacity and high accuracygood run with low speed and heavy friction superior performance
Polytetrafluoroethylene fiber PTFE/Kevlar
VIIPLUS TEX ptfe fiber metal base self-lubricating bearing is a self-lubricating composite bearing material made of high-quality low-carbon steel plate, bronze plate or stainless steel plate as the matrix, with the woven fabric of ptfe fiber as the friction surface layer.
The two are rolled into sliding bearing by means of a solid bond of structural adhesive.In order to guarantee the bonding strength between ptfe fiber and metal sheet, the woven fabric is made of special ptfe filament and aramid filament.
The bearing has the characteristics of high bearing capacity, good wear resistance, suitable temperature, wide range of medium, simple structure, compact size and good stability.
Polytetrafluoroethylene (ptfe) is a kind of self-lubricating material with excellent performance.But the wear resistance is poor because of the low strength.At present, most of the fibers or other fillers are used to improve the wear resistance, the effect is very limited.And polytetrafluoroethylene fiber has tensile strength 15 times higher than pure polytetrafluoroethylene resin, to make up for the lack of this aspect, wear resistance is greatly improved, at the same time, the fiber also avoids the occurrence of cold flow phenomenon of polytetrafluoroethylene resin.
Polytetrafluoroethylene fiber metal base self-lubricating bearings are divided into steel base, copper base and stainless steel base three.
Maximum load pressure: 180Mpa
Friction factor: 0.03~0.20
Operating temperature range: -90 ° C ~ 180 ° C
Fiber bearing can be used in seawater, gasoline, hydraulic oil, engine oil, kerosene, lubricating oil, weak acid, ammonia water, liquid nitrogen, toluene, washing fluid and other media.
Fiber bearing is the most suitable for high load, low speed, oil film can not be maintained or formed, can not use lubricants, impact load is large, corrosion resistance, swing and other conditions of the use of the bearing, the specific application is as follows:
Hydropower station: turbine water guide mechanism, ball valve, butterfly valve;
Heavy lift systems for trucks, tractors, forklifts and related equipment, such as rocker arm bushing, etc.;
Steering system, braking system and connecting rod fulcrum of clutch of trucks, buses and agricultural tractors;
A motor steering system, such as a motor pivot, is installed externally at the stern;
Butterfly valve and ball valve, bearing comply with NSF drinking system structure parts health standards;
Food machinery, textile machinery, printing machinery, tobacco machinery, packaging machinery, medical equipment and so on;
Supporting bearings for Bridges, pipelines and other structures;
Lifting machinery, especially the main boom, moving boom, foot fulcrum and other parts of the fulcrum can not be lubricated.
Strong impact load resistance, no "crawling" phenomenon, smooth operation;
High wear resistance, good corrosion resistance, no cold flow phenomenon;
Good dimensional stability (no expansion in water), non-conductive, non-magnetic;
Bearing is thin wall structure, light weight, small volume, suitable for compact design;
Low friction woven fabric oilless bearing VSB-36 TEX is widely used in high temperature production lines, construction machinery, automobile chassis parts, ball valves, butterfly valves, pumps and chemical industries and high-speed trains and other heavy low and cannot refuel occasion etc.
This new material use the PTFE fibres fabric overlay on metal backings.
The fabric has very high load capacity and much longer operating life compared with conventional 3-layer bushes.
The metal can be Carbon steel , Stainless steel, Bronze etc.

Preparation and Properties of ptfe fiber braided Self-lubricating Composites
Polytetrafluoroethylene (PTFE) fiber fabric self-lubricating composite material is a new kind of solid self-lubricating material,PTFE fiber fabric retains the low friction coefficient of PTFE material at the same time, and has a high mechanical strength.Therefore, as the lubrication layer between the inner and outer rings of joint bearing, it is widely used in aerospace, automobile, large machinery and other fields.In this paper, PTFE fiber and Kevlar fiber were used as raw materials to weave PTFE fiber fabric by weaving machine. After the surface treatment of sodium naphthalene complexate solution, the self-lubricating composite material of PTFE fiber fabric was prepared by phenol-epoxy adhesive and bonding curing treatment of 45# steel.The friction coefficient and wear amount of PTFE fiber and the effect of surface treatment on the friction properties of composites were measured by friction and wear testing machine.The friction surface was characterized by scanning electron microscopy and the friction mechanism was analyzed.The interlining materials of woven fabric and finished fabric are compared and analyzed.The results show that the surface treatment with sodium naphthalene complex solution can strip the F element from the surface of PTFE fiber fabric, enhance its bonding strength with metal, but also reduce the wear resistance of PTFE fiber fabric to a certain extent.And the shorter the surface treatment time is, the smaller the reduction of wear resistance will be.In addition, the surface treatment of sodium naphthalene complex solution has little effect on aramid fiber and Kevlar fiber.After surface treatment for 5min, the friction surface of the sample produced more debris and abrasive wear.The higher the content of PTFE fiber in the self-woven fabric, the better the anti-wear performance of the fabric. For the fabric with 30% fiber content, the higher the friction speed is, the higher the friction coefficient is.On the contrary, for fabrics with 80% PTFE fiber content, the higher the friction speed, the lower the friction coefficient.
