A supporting roller bearing is a bearing unit consisting of a machined thick wall outer ring, a needle roller or cylindrical roller, or a cage guide or full pack of rolling elements, an inner ring or a bolt and seal.
Structural features:
The outer ring supporting the roller bearing is usually thick, and the external profile is curved, which helps to improve the rigidity and bearing capacity of the bearing. The rolling element can be a cage assembly or a fully loaded rolling element assembly, which is designed in single and double row forms. The bearing has a wide range of outer diameter sizes, usually between 16mm and 110mm, and the inner hole size range is between 5mm and 50mm.

Applications
Support roller bearings are widely used in various heavy duty and medium speed operating occasions, such as CAM and transmission systems. They are able to withstand extremely high radial and axial loads and operate stably despite slight misalignment of components and tilting during operation. In addition, this type of bearing is also suitable for inner ring rotation, often used in lifting drums and other equipment, the need to use the clamp ring for axial fixation.
