Мере предострожности за уградњу heterosexual mica processing parts

1. Before assembling, make sure that there is no foreign matter on the surface of the shaft sleeve and the seat hole, and the surface of the seat hole should be as smooth as possible to avoid scratches during assembly.

2. Appropriate lubricating oil can be applied to the outer surface of the shaft sleeve during assembly to help the shaft sleeve to be installed more conveniently, but it is not easy to be too much to prevent the shaft sleeve from falling out during heavy load or reciprocating motion.

3. When assembling, the mandrel should be slowly pressed in, and it is forbidden to knock on the sleeve to avoid deformation.

4. In order to make the assembly easier and the cutting will not damage the wear-resistant layer, the end face of the shaft must be chamfered and smooth. The shaft material is recommended to be bearing steel surface quenched HRC45, the surface roughness is Rz2-3, and the surface can be plated with hard chrome .
