More Information:
In this series, the caged cylindrical rollers AZK and the complete bearings AZ in which AZK are combined with an inner ring (WS) and an outer ring (GS) are available. The cage has a special precise structure which is highly rigid, and cylindrical rollers are outwardly arranged and guided by the cage with exact precision to enable them to withstand heavy loads even at high rotational speeds. Owing to the high accuracy of the bearing height (T Dimension), they are suitable for use in machine tools and ultra-high-pressure pumps. These bearings are generally used by utilizing their inner surface as the guide surface.
