Bearings - Mounted Units
Mounted unit bearings, commonly referred to as pillow block and flange bearings, are a distinctive family of bearings because the bearing unit is considered as a product item, when in fact it actually consists of a ball or roller bearing installed within a separate fixture called the housing.

These housings are most commonly made of cast iron but may also be made of other metals or nonmetallic materials. The housing provides rigidity and secure positioning for the bearing within the application. It also simplifies the task of replacing the bearing, as the housing and bearing can be replaced as a complete unit.

When selecting a mounted unit, consider:

* The housing properties and characteristics that hold the insert bearing
* The insert bearing properties and characteristics
* The seals that protect the bearing
* Maintenance-free and relubrication type units, and their lubrication
* Locking devices for fixing the unit to the application
* Proper methods for mounting the units.
