This is an environmentally friendly, lead-free bearing, the material structure of which consists of multiple layers of PTFE, porous intermediate layer and steel backing (similar to that of DDK05 dry bearings. Due to improved sliding and porous layers, boundary surface performance and fluid lubrication have also improved.
