WGB-2 Marginal Self- lubricating Bearings
WGB-2 Marginal Self- lubricating Bearings,The product is based on high-quality low-carbon steel, sintered spherical bronze layer in the middle, and surface-rolled modified polyoxymethylene (POM). Under boundary lubrication conditions, it can be used for a long time without adding oil, and there are oil storage pits on the surface of the wear-resistant layer.
