Modern bearings are greatly advanced components that are the outcome of intensive research into elements and bearing geometries, but how they are maintained in duty — in other terms, how are they housed – determines their final performance. In this post, we'll go over the various types of housed bearings and their uses, along with several key design considerations.

Housed bearings are flexible components that make it simple to install bearings and shafts while also protecting them, increasing their life, and easing maintenance. Split Plummer/ pillow block housings, take-up housings, non-split Plummer form of block housings, flanged housings, and two-bearing housings are the five standard and different kinds of housings. Specific duty requirements, such as speed, load, and operating ambient conditions, can be fulfilled using the housed bearings products.

Non-standard housed bearing designs can also be manufactured and provided to meet specific customer needs, such as where special shaft center heights, unconventional sealing arrangements, or non-standard building materials may be specified.

Split Plummer form of block housings is a fantastic alternative for ease of installation and maintenance since they not only fit pre-assembled shafts but also facilitate bearing inspections and maintenance because the shaft does not require to be dismantled at all.  These units are manufactured and designed for spherical roller bearings, self-aligning ball bearings, and CARB toroidal roller bearings are all quite compatible. When heavy loads are applied in a direction apart from toward the support surface, the non-split Plummer form of block housings is ideal. They are also utilized when the housing requires to be fixed from the end of the shaft.

Rigid bearings, like the angular contact ball bearings, deep groove ball bearings, and cylindrical roller bearings, can be handled in two-bearing housings because the bearing seats are naturally aligned. In applications with an over-drooping load, two-bearing housings are commonly used in these cases.

The most frequent components for housed bearings are spheroidal graphite cast iron, grey cast iron, and cast steel. Grey cast iron is the most popular and appropriate for most purposes, providing a mix of good damping, high strength, and great heat conductivity. Spheroidal graphite cast iron is much more ductile than grey cast iron, which means it has more strength and toughness. It can handle a weight of nearly twice as heavy as grey cast iron. Where corrosion is a concern, bearing housings can be provided in composite materials, coated cast iron, or cast steel, stainless steel.

Another key role is to keep track of the bearing's duty performance. Regular visual inspections or a condition monitoring system can be used to do this, with the latter being especially important for essential installations. The vibration signal is the most often monitored characteristic, and the bearing condition is assessed by evaluating variations in the vibration signature.
