Most types of plain and rolling-element bearings are available in mounted units, eliminating the need to select and assemble different components. Housed bearings provide shaft support for radial, thrust, or a combination of loads. Mounted bearing types include pillow blocks (solid or split), flanged cartridges, cylindrical cartridges, and take-up units.

Types of Mounted Bearings

Pillow Block (Plummer Block)

This is the most common type of mounted unit. The mounting base plane is perpendicular to the shaft and the bolt holes are parallel to the shaft. They can be used on vertical, horizontal, and inclined surfaces. Pillow block bearings are constructed of a housing and an insert bearing, which are usually self-aligning. Split housing styles are available for easy dismantling and bearing replacement. Standard-duty types have two mounting holes and heavy-duty types have four mounting holes.

Flanged Cartridge

These units are usually mounted on vertical surfaces where the shaft passes through a machine frame at a right angle. A piloted, flanged cartridge is available to provide better mounting and support. Cylindrical cartridges provide support where the shaft axis is perpendicular to and passes through machined housings.

Take-Up Units

These are used to adjust the center distance between shafts or where belt-tightening is required. Complete take-up units are available for both horizontal and vertical adjustments and top or side mounting.
