Product Description

Thrust Washer Bearing PTFE

THRUST WASHER BEARING SUPPLIER PLAIN BUSHES

Simply called is three layers of composite meaning, -1 refers to the material description is PTFE, SF-1 bearing is a layer of steel plate as the matrix, a layer of intermediate sintered spherical bronze powder, a layer of inner surface rolling polytetrafluoroethylene (PTFE) and lead mixture, by three layers of rolling bearing. And has the characteristics of small friction coefficient, wear resistance, high corrosion and no oil lubrication.

The basic concept
Simply called is three layers composite meaning, -1 refers to the material description is PTFE, SF-1 bearing is a steel plate as the matrix, a middle layer of sintered spherical bronze powder, a layer of inner surface rolling polytetrafluorethylene (PTFE) and lead mixture, by three layers of rolling Ming Sheng bearing. And has the characteristics of small friction coefficient, wear resistance, high corrosion and no oil lubrication. Using this product can reduce the cost, reduce the mechanical volume, avoid the phenomenon of biting shaft and reduce the mechanical noise and so on. Sf-1 products have been widely used in the sliding parts of all kinds of machinery, such as printing presses, textile machines, fitness equipment, hydraulic carriers, micromotors, automobiles, motorcycles and agricultural and forestry machinery.

Thrust washers are flat washers that are located between a rotating surface and a stationary component. They support the axial load or side to side motion on a shaft and prevent movement along that shaft. The thrust washer provides a surface on to which a bearing is supported.

Sf-1 oil-free bearing is a sliding bearing made of steel plate as base, sintered spherical bronze powder in the middle, and a mixture of rolled polytetrafluoroethylene (PTFE) and lead on the surface. It has the characteristics of small friction coefficient, wear resistance, good corrosion resistance, no oil lubrication. This product can reduce the cost, reduce the mechanical volume, avoid the phenomenon of biting shaft and reduce the mechanical noise and so on.

 

1, no oil lubrication or less oil lubrication, suitable for the place can not be refueled or difficult to refueling, can be in use without maintenance.

 

 

 

2. Good wear resistance, small friction coefficient and long service life.

 

 

 

3, has the right amount of elastic-plastic, can distribute the stress on a wider contact surface, improve the bearing capacity of the bearing.

 

 

 

4, the static and dynamic friction coefficient is similar to eliminate the crawling at low speed, so as to ensure the working accuracy of the machine. 5, can make the machine to reduce vibration, reduce noise, prevent pollution, improve and optimize the working environment.

 

 

 

6, in the process of operation can form a transfer film, to protect the use of grinding shaft, no biting shaft phenomenon.

 

 

 

7. The hardness requirements of grinding shaft are low, and the shaft without quenching and tempering treatment can be used, thus reducing the processing difficulty and cost of related parts.

 

 

 

8, thin-walled structure, light weight, reduce the mechanical volume.

 

 

 

9, the back of steel can be electroplated a variety of metals, can be used in corrosive media; At present, it has been widely used in the sliding parts of various machines. Such as automation machinery and equipment (scale, swing, slide, bending, cyclotron, turning parts) guide bush, hydraulic motor, hydraulic cylinder gear pump pu, textile machinery, vending machines, plastic molding machine, die-casting machine, rubber machine, tobacco machine, fitness equipment, office machinery, hydraulic truck, automobile, motorcycle, forestry machinery, etc.

SF-1 Thrust Washer Advantages:

 

  1. Can be used where no oil can be applied or oil is difficult to be applied.

  2. Low wear, low friction and with long life.

  3. Low stick slip properties ensuring accuracy of machine operation under low sliding speeds.

  4. Low vibration, low noise and non-pollution in operation.

  5. PTFE and Lead filler is transferred to the mating shaft to improve running properties.

  6. Can be used in low hardness of mating shaft, so the shafts processing is easy.

  7. The machine will be compact because of the thin thickness and low weight of the washer.

  8. Electro plating is possible to prevent corrosion.

 

SF-1 Thrust Washer Typical Applications:

 
PTFE coated thrust washers TSB-1W is widely applied in various sliding motions of different kind of machines, such as textile machines, tobacco machines, hydraulic vehicles, automobiles, agricultural machines and so on.
