To ensure effective sealing, plummer blocks are available with a variety of special sealing options and end covers. Benefits include a facility for easy mounting and dismounting of pre-assembled shafts.
Plummer block housings can be used with high-capacity spherical roller bearings or self-aligning ball bearings. They 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.
Split plummer block design allows for easy mounting and dismounting of pre-assembled shafts.
