What's CM1(SF-1B)？

CM1(SF-1B) simply called is the meaning of three-layer composite, -1 refers to the material description is PTFE, CM1(SF-1B) bearing is a layer of steel plate as the substrate, a layer of the middle sintered spherical bronze powder, a layer of the inner surface of the rolled polytetrafluoroethylene (PTFE) and lead mixture, from three layers rolled into the Mingsheng bearing. And has a small coefficient of friction, wear-resistant high corrosion and good oil-free lubrication characteristics. The use of the product can reduce costs, reduce the volume of machinery, to avoid the phenomenon of gnawing shaft and reduce mechanical noise and other advantages. sf-1 products have been widely used in a variety of machinery sliding parts, such as printing machines, textile machines, fitness equipment hydraulic trucks, micro motors, automobiles, motorcycles and agricultural and forestry machinery, etc..

CM1(SF-1B) features.

1、No oil lubrication or less oil lubrication, suitable for places where it is impossible to add oil or very difficult to add oil, can be used without maintenance or less maintenance.

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

3, there is a moderate amount of elasticity, can distribute the stress in a wider contact surface, improve the bearing capacity.

4, static and dynamic friction coefficient is similar, can eliminate the crawling at low speed, so as to ensure the working accuracy of the machinery.

5、It can make the machinery reduce vibration, reduce noise, prevent pollution and improve labor conditions.

6、The transfer film can be formed during the operation to protect the shaft of the grinding, no gnawing phenomenon.

7、The hardness requirement for the grinding shaft is low, and the shaft without tempering treatment can be used, thus reducing the processing difficulty of related parts.

8、Thin-walled structure, light weight, can reduce the volume of machinery.

9、The back side of the steel can be plated with various metals and can be used in corrosive media; it has been widely used in the sliding parts of various machines.

Working temperature (use precautions)

SF-1 working temperature is generally below 240℃, better than SF-2 temperature resistance, SF-2 general temperature resistance at 90℃. ('a little' is 'below')
