Roller Bearings


Roller bearings permit much greater radial loads to be carried, due to a cylindrical shape that creates a linear contact patch. Radial loads are dispersed over this larger contact patch, delivering much greater capacity than a similar-sized ball bearing. Further design innovations allow variant roller bearings that can also handle heavy axial forces. Conveyor belts and large equipment are the most typical platforms requiring roller bearings.

Common types of roller bearings are summarized as follows:

Cylindrical Bearings: These bearings provide unmatched performance in radial load capacity, perfect for heavy equipment and out-sized operations. Typically formatted in row configurations, ex. single-row cylindrical bearings for standard applications and up to four-row cylindrical bearings for extremely high radial load requirements.

Taper Roller Bearings: Designed to offer balanced performance for large axial forces as well as large radial forces. Conical geometry is the key design attribute, which provides a large contact patch and ability to carry higher loads. Taper roller bearings are also produced in row configurations of increasing load capacity.

Spherical Roller Bearings: These bearings offer consistent performance for the toughest applications. In cases where extreme speed, non-optimal lubrication, misalignment, and/or other performance challenges are common, spherical roller bearings provide best results in carrying heavy radial loads.

Thrust Bearings: These bearings are optimized to handle high axial (thrust) loads. Typically thrust bearings are used in high-speed applications, with generally lighter loads. Thrust bearings have a number of different variants, some of which allow for greater loads at reduced speeds.

Needle Roller Bearings: The small cylindrical bearings of needle roller bearings ensure the smallest possible friction profile
