Self-Lubricating Steel Metric Flat Washers for Valve Bearing are designed to provide smooth and reliable operation in valve bearing applications. Constructed from steel and coated with (Polytetrafluoroethylene), these washers offer excellent wear resistance and self-lubricating properties. The metric sizing ensures compatibility with a wide range of valves and bearing systems, making them a versatile solution for various industrial applications. The coating reduces friction and enhances lubrication, ensuring long-lasting performance and reduced maintenance requirements.
SF-1 teel self-lubricating bearings used high quality low-carbon steel plate as base, sintered porous bronze as its interlayer and the Compound of and Lead as its surface. It offers the property of good self-lubrication, low wear, low friction good sliding characteristics, low noise. It has been widely applied to various mechanical sliding positions, such as textile machinery, printing machinery, hydraulic pressure transit vehicle, tobacco machinery, gymnastic instrument and agricultural machinery etc.
Choose from our selection of thrust bearings in a wide range of styles and sizes.

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. 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.
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.
