PVB020W Steel Back POM Coated Boundary Lubricating Composite Plain Bearing Shell
PVB020W POM lined sliding bearing is a made of steel back sintered bronze with POM coating. This type boudnary lubricating bushing has always been made as split bearing, half bearing bushing, Bearing Shells. PVB020W sliding bearing is also called boundary lubricating bearing,DX bearing,SF-2 oilless bearing,PAP P20 composite plain bearing and dry bushes.
