Bearing housings are modular assemblies used to mount bearings to a mounting surface, facilitate bearing installation, or protect bearings
and extend operating life. A multitude of designs are available to meet different operating requirements, including split plummer block housings or pillow block housings, non-split plummer block housings, flanged housings, two-bearing housings and take-up housings. Split plummer block housings are specialized for ease of installation and maintenance; they can also accommodate pre-assembled shafts. They are often designed for spherical roller bearings, CARB roller bearings
, and self-aligned ball bearings. Non-split plummer block housings are suitable for higher load capacity applications and loads acting away from the support surface. Flanged housings are designed for applications where the mounting surface is perpendicular to the shaft axis. They are available in a multitude of shapes and designs to accommodate different mounting surfaces. Take-up housings are mainly used to maintain tension in conveyor belt applications, and are mounted onto a guide frame. Two-bearing housings have aligned bearing seats to accommodate rigid bearings such as cylindrical roller bearings
, deep groove ball bearings, and angular contact ball bearings. They are suitable for applications with an overhanging load. Bearing housing materials include grey cast iron, spheroidal graphite cast iron, and cast steel, however other metals or plastics may be produced, depending on the manufacturer. Most bearing housing units come with all necessary assembly components and a bearing insert, however bearings can be interchangeable and insert bearings are available separately; Check out the large selection at MRO Supply for all bearing options.
