The choice of housing material should be based on specific application requirements and working environment.

 The performance of preventing adhesion and boundary lubrication when the shaft diameter is in direct contact with the bearing bush. The material factors that affect the friction compatibility of the friction pair

The performance of preventing adhesion and boundary lubrication when the shaft diameter is in direct contact with the bearing bush. The material factors that affect the friction compatibility of the friction pair are:

Fault phenomenon: After the automatic oil pump, if pure liquid lubrication has been established, it should generally be able to rotate easily by hand; if it cannot rotate or is more difficult to rotate than when no oil is supplied, it means that pure liquid lubrication has not been established.

Mechanical polishing Mechanical polishing is a polishing method that relies on cutting and plastic deformation of the material surface to remove the polished convex parts to obtain a smooth surface. Generally, oilstone strips, wool wheels, sandpaper, etc. are used. Mainly manual operations, special parts such as rotary bodies For the surface, auxiliary tools such as turntables can be used. For those with high surface quality requirements, ultra-precision grinding and polishing can be used. Super-precision polishing uses special abrasives, which are pressed against the surface of the workpiece to be processed in a polishing fluid containing abrasives to perform high-speed rotation. This technology can achieve a surface roughness of Ra0.008μm, which is the highest among various polishing methods. This method is often used for optical lens molds.
