JLB-1P Reciprocating motion bearings
Detailed description
The material is based on shock absorbers and lateral reciprocation larger force of special conditions and development of products. It has a very low coefficient of friction and good wear resistance, can be used in the lubrication gap. The major products in automotive shock absorbers, motorcycle shock absorbers, hydraulic cylinder and so on.
