Details
Cylindrical roller bearings are essential components used in various industrial applications to support radial loads and high rotational speeds. It consists of an inner ring, an outer ring, cylindrical rollers, and a cage. The NJ Bearing Series have two fixed ribs on the outer ring and a fixed rib on the inner ring which can guide the shaft in a single direction (axially). The ECJ design have a pressed steel cage and an optimized internal design for improved performance.
