Overview
Technical Parameter
This product is based on high-quality low-carbon steel, with a sintered spherical bronze layer in the middle, and a mixture of surface rolled modified polytetrafluoroethylene (PTFE) and lead. It has good self-lubricating, wear-resistant, low friction coefficient, good running in performance, low noise and other properties. The product is widely used in the sliding parts of various machinery, such as textile machines, printing machines, hydraulic transport vehicles, tobacco machines, fitness equipment, agricultural machinery, etc.
