This is a split plummer block housing designed to accommodate a spherical roller bearing with cylindrical bore, matched to metric shaft diameters. The housing splits along the horizontal plane, so the bearing can be fitted or removed without shifting the shaft assembly out of position. Net mass of the housing is 955.7 kg, and the design is intended for grease lubrication only, with no provision for oil. The split construction simplifies mounting and inspection, since the cap can be lifted off independently of the base. Combined with a spherical roller bearing, the housing tolerates shaft misalignment and deflection that a rigid bearing arrangement would not accept. Grease lubrication keeps servicing straightforward, without the need for a circulating oil system or associated sealing arrangements.
