SF-1X

SF-1X

SF-1X oil-free lubricated bearing is a rolling sliding bearing made of steel plate as the matrix, sintered ball shaped bronze powder in the middle, and a mixture of polytetrafluoroethylene (P polyTFE) and lead rolled on the surface.

Material organizational structure

1. PTFE and lead mixture 0. 01-0. 03mm

2. Spherical bronze powder 0. 2-0. 3mm

3. Steel back 0. 7-2. 3mm

4. Electroplating layer: tin plating layer thickness 0. 005mm, or copper plating thickness 0. 008mm


Product Details

Application features


1. No oil lubrication or less oil lubrication, suitable for places where oil cannot be refueled or it is difficult to refuel, and can be used without maintenance or less maintenance.

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

3. There is an appropriate amount of elastic plasticity, which can distribute the stress on a wide contact surface and improve the bearing capacity.

4. The static friction coefficient is similar, which can eliminate crawling at low speed, so as to ensure the working accuracy of the machine.

5. It can reduce vibration, reduce noise, prevent pollution and improve working conditions.

6. During the movement process, a transfer film can be formed, which plays the role of protecting the motor shaft without biting the shaft.

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

8. The structure of the book wall, light weight, can reduce the mechanical volume.

9. The back of the steel can be electroplated with a variety of metals, which can be used in corrosive media; At present, it has been widely used in the sliding parts of various machinery.

For example: printing machines, textile machines, lifts, tobacco machinery, fitness equipment, hydraulic transfer vehicles, solenoid valves, micromotors, automobiles, motorcycles, agricultural and forestry machinery, etc.
