SF-1P reciprocating move material

  • parameters

SF-1P reciprocating move material is a novel formula designed according to the special working conditions of reciprocating motion, and its performance is similar to that of foreign DD2. The utility model has the advantages of strong self-lubricating ability, good wear resistance and clear oil film under the condition of oil-cutting, and the material can better protect the surface of the grinding shaft from abrasion. At present, the material products have been widely used in automobile shock absorbers, motorcycle shock absorbers, various hydraulic cylinders, hydraulic motors, pneumatic components and the like.
