Mounted units consist of two basic components, the insert and the housing. Each mounted unit includes a sealed single-row ball bearing with spherical outside diameter and extended inner ring mounted in a pillow block or flanged housing. The spherical fit accommodates initial misalignment.

A variety of locking methods are available for close-fit shaft mounting as well as a complete range of sealing options for varying environments.

The bearing units are available in many different versions as a vertical bearing block, flange bearing block or clamping bearing unit. The units are ready for assembly and consist of housings made from cast iron or sheet steel into which the Y-bearings or clamping bearings are integrated. In order to ensure correct functioning under all operating conditions, bearings and bearing housings are matched with each other.

Due to the spherical shell of the bearing outer ring and the concave structure, the ball-shaped bore of the bearing housing can set itself lower to compensate for static misalignments. The units are normally used as fixed bearings, but in the case of low loads and speeds, they are also suitable as floating bearings. The housing units can be attached to the connecting construction with screws. There are no high requirements for the mounting surfaces.
