Plummer Blocks Bearings are constructed of a housing and a bearing. Bearings used with Plummer Blocks housings usually are self – aligning to compensate for angular misalignments. Plummer Blocks housings can be used with high – capacity Spherical Roller Bearings or Self -Aligning Ball Bearings. Plummer Blocks are manufactured from high – strength cast iron as standard but are also available in cast steel or spheroidal graphite cast iron. The housings have a re – lubrication facility and can be used with either oil or grease lubrication.
