Non-Locating BX
Locating BR

Our non-located bearings handle
thermal growth better

In most bearing applications, there are located (fixed) bearings and non-located (free) bearings. The reason for this is that the located bearing holds the shaft in position while the non-located bearing allows for thermal growth of the shaft.

The split bearing method of accommodating thermal growth is far superior to the plumber block method as it is able to tolerate axial displacement and mis-alignment simultaneously. This allows it to be used in applications that specifically need to accommodate excessive thermal grwoth, for example, in blood cookers

 

Non-Locating BX

This bearing is designed for radial loads only. As in the retained type bearing, the rollers are guided on the inner race by the hardened shoulders of the clamping rings.

Note how the roller and inner race assembly is free
to move along the outer race to allow for axial expansion

 

Locating BR
This bearing has integral lips on the outer race to
provide a surface for axial load. This axial load is
accommodated on the inner race via the hardened
clamp rings, which both align the inner race halves and provide roller guidance. In larger bearings the inner race is manufactured with integral ribs for roller guidance and axial load.
