WGB-1（Sn）
WGB-1（Sn）Oilless Bushing，It is a sliding bearing made of steel plate as the matrix, spherical bronze powder sintered in the middle, and a mixture of polytetrafluoroethylene (PTFE) and lead rolled on the surface. It has the characteristics of low friction coefficient, good wear resistance, good corrosion resistance and no oil lubrication.
