The Plummer Block, as known as (Split/Non-Split) Plummer Block Housing, which is an assembly comprising of a self-aligning ball bearing or spherical roller bearing placed in bearing boxes of various shapes, has a large load capacity and is easy to handle, therefore it is widely used in general industrial machinery such as conveyors.

Plummer Block Housings 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.

BND series One-Piece Bearing Housings are produced in cast steel, stainless steel, cast iron and ductile iron. BND bearing Housings are originally developed for belt conveyor. These plummer block housings are successfully used in processing engineering applications. This design offers high operational reliability with little maintenance requirements which are very essential features for conveyor applications. We machine BND Series bearing housings to suit any bearing size. They are a one-piece bearing housing, ideally suited to a harsh and extreme working environment. The sealing arrangement is of a taconite design which protects the bearing from dusty and dirty conditions. Labyrinth seals also can be provided.
