Needle roller bearings are a type of industrial roller bearing that uses small diameter, long length rollers as rolling elements. This structure allows the bearing to have a high load-bearing capacity despite its small dimensions and compact design.
One of the prominent features of these roller bearings is reduced friction and increased strength against heavy loads. Due to the small diameter of the rollers, the load is distributed more effectively, which increases the service life and reduces wear of adjacent parts.
Needle roller bearings are available in various models, including models with a cage, models without a cage (full complement) and models with an internal bushing. Models without a cage can accommodate a larger number of rollers, so they have a higher load capacity, but are not very suitable for high speeds.
