Cylindrical Roller Bearings FAG NJ2211 -E-M1

The FAG NJ2211 -E-M1 cylindrical roller bearing is a single-row support bearing with a brass cage, measuring 55 x 100 x 25 mm, designed for high radial loads.

The NJ2211 -E-M1 cylindrical roller bearing from FAG Rolling Bearings is designed as a single-row radial roller bearing for demanding industrial applications. Thanks to the line contact between the rollers and raceways, the design can accommodate high radial forces. With dimensions of 55 mm bore, 100 mm outer diameter and 25 mm width, this version offers standard radial clearance and tolerance class P0/PN or ABEC 1. The open bearing has an outer ring without a lubrication bore and is suitable for operating temperatures ranging from -30 to +150 degrees.

What is the NJ2211 -E-M1 cylindrical roller bearing suitable for?

This rolling bearing is primarily used as a support bearing in mechanical bearing arrangements where high radial forces are the main consideration. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, the bearing absorbs axial forces from one direction, whilst the inner ring remains axially movable to one side. This feature facilitates length compensation in the event of temperature-induced shaft expansion.

What are the key features of the NJ design with a brass cage?

The brass cage (-M1) guides the cylindrical rollers reliably and is suitable for applications involving high levels of vibration and dynamic loads. As the inner ring can be removed from one side, the bearing can be fitted separately onto the shaft and housing. As an open design, the unit requires an external lubricant supply via oil or grease in the adjacent structure, which is also intended to prevent the ingress of dirt particles.
