SF-1D Hydraulic special bearingsDetailed product description：

SF-1D hydraulic special bearing is a new type of material designed based on the working principle of oil cylinder and shock absorber on the basis of SF-1P. Its performance is similar to that of foreign DP4. In addition to the advantages of SF-1P, this product is particularly suitable for high lateral force applications with frequent reciprocating. At present, this product is gradually replacing SF-1P products and is suitable for automotive, motorcycle shock absorbers, as well as various hydraulic cylinders and other fields.

SF-1D hydraulic special bearings are available in various forms, including straight sleeve, flanged, thrust washer, sliding plate, and other non-standard components.
Tolerance: It is generally recommended to have a seat hole tolerance of H7 and a shaft diameter tolerance of f7 or h8.
