Quantity:


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 NUP Series have two fixed ribs on the outer ring and a fixed rib with a support washer on the inner ring.  This way they can be used as locating bearings, guiding the shaft axially in both directions. The ECJ design have a pressed steel cage and an optimized internal design for improved performance.
