ZYB-1D hydraulic special bearing. It is a new type of material designed on the basis of SF-1P and combined with the working principle of oil cylinder and shock absorber. It appears wear-resistant under oil-free conditions. In addition to the advantages of SF-1D, this product is especially suitable for frequent reciprocating. For occasions with large lateral force. Its performance is similar to that of foreign DP4. At present, this product is gradually replacing SF-1P products, and is suitable for automotive and motorcycle shock absorbers and various hydraulic cylinders.
