[Application Features] PAP-P oil-free self-lubricating bearings Steel substrate, middle sintering spherical bronze powder, the surface rolling polytetrafluoroethylene (PTFE) and lead a mixture, rolling a sliding bearing. It has a low coefficient of friction, wear resistance, corrosion resistance, no oil lubrication characteristics. Use the product can reduce cost, reduce mechanical volume, avoiding the phenomenon of bite-axis and reduce mechanical noise and other PAP composite bearings
