Introduction

SF-1P Reciprocating Bearings is based on the SF-1 material, according to the special conditions of reciprocating motion design of the new formula product, its performance and foreign DD2 similar. With oil-off conditions under the self-lubricating ability, wear resistance, and maintain the advantages of a clear oil film, the product can better protect the wear-free surface of the mill shaft. At present, the product has been widely used in automobile shock absorber, motorcycle shock absorber, all kinds of hydraulic cylinders, hydraulic motors, pneumatic components, and other fields.
