SF-1P product description
SF-1P reciprocating motion bearing is a novel formula product designed on the basis of the structure of SF-1 material and according to the special common conditions of reciprocating motion. Its performance is similar to that of foreign DD2. Because it does not contain lead, it meets environmental protection requirements.
