Bajaj bearings units are intended mostly for applications calling for simplicity of design and assembly.Pillow Block Bearings are used, for instance, in agricultural machinery, conveying equipment, and construction machinery. A Pillow Block bearing unit consists of a deep groove ball bearing sealed on both sides and a spherical outside diameter together with housing, which is either a casting or a sheet metal stamping.  Pillow Block bearings these units are supplied as Plummer block or flanged housing mountings.

The Bajaj Bearings covers the current units for metric and inch size shaft. Apart from very rare exceptions Pillow Block Bearings bearing units are used as locating bearings. They are particularly suited for short shaft and for applications where only minor thermal expansions occur. Small shaft expansions are absorbed by the axial clearance in the bearings. Plummer block unit housing made of cast iron, Flanged-housing unit made of sheet metal.

Flanged housings of smaller sizes are triangular and the larger sizes have a square shape. They can be used for self-aligning ball bearings and spherical roller bearings. They can be used for tapered bores on an adapter sleeve on smooth shafts.

They require felt seals and grease lubrication. Pillow block bearings are made of gray cast iron. Different types of flanged ball bearings are used for mild and harsh conditions
