SF-1D hydraulic special material

  • parameters

SF-1D hydraulic special material is a material designed in combination with the working principle of oil cylinder and shock absorber. It is more wear-resistant under oil-free conditions. In addition to the advantages of SF-1P, this product is especially suitable for large reciprocating Tendency to the occasion.

Its performance is similar to that of foreign DP4. At present, this product gradually replaces SF-1P material, and is suitable for use in automobile, motorcycle shock absorbers and various hydraulic cylinders. This material is lead-free and meets the requirements of the EU ROHS Directive.
