Steel-Backed Tin-Plated Thrust Washer Bearing with PTFE Coating is a high-performance bearing designed to withstand heavy loads and provide smooth, reliable operation in thrust applications.

Constructed with a steel backing, this bearing offers exceptional strength and durability, making it suitable for use in demanding industrial environments. The tin plating adds an extra layer of protection, resisting corrosion and wear, while also improving lubrication properties.

The PTFE (Polytetrafluoroethylene) coating provides a low-friction surface that significantly reduces friction and heat generation during operation. This not only enhances the bearing's efficiency but also extends its service life.

The thrust washer design of this bearing allows it to distribute loads evenly, reducing stress concentrations and minimizing wear. Whether you're upgrading existing equipment or installing new machinery, the Steel-Backed Tin-Plated Thrust Washer Bearing with PTFE Coating is an excellent choice for improving performance and reliability.

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.

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.
