Self-lubricating Bearings

HLDB Metal-polymer self-lubricating bearings consist of low carbon steel and sintered bronze in the middle with PTFE compounded on the surface. It is lighter and has better mechanical and load performance. Low carbon steel gives exceptionally high load carrying capacity. Sintered bronze powder connect plastics and assisting friction reduction. PTFE layer plays the role of wear resistance to protect the mating metal surface. It has good capacity for low coefficient of friction, low wear rate, lower-noise and good sliding characteristics. It is suitable for dry running and performs well in general industrial area.
