Cylindrical Roller Bearings FAG NU2322 -E-XL-M1A-C3

The FAG NU2322 -E-XL-M1A-C3 cylindrical roller bearing, measuring 110 x 240 x 80 mm, offers high radial load-carrying capacity as a separable idler bearing with a brass cage.

The FAG NU2322 -E-XL-M1A-C3 cylindrical roller bearing is a single-row radial roller bearing designed for heavy mechanical loads. In the NU design, the bearing has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, which simplifies the separate assembly of both bearing rings. Designed for purely radial forces, this version accommodates axial displacement of the shaft within the housing without constraint.

What is the NU2322 -E-XL-M1A-C3 cylindrical roller bearing suitable for?

This non-locating bearing is designed to accommodate high radial forces in heavy-duty mechanical drive systems. As the flangeless inner ring compensates for thermal length changes in the shaft without resistance, this design prevents internal stresses within the bearing system. The combination of a robust roller guide and a solid construction is designed for continuous radial loads, in which the open bearing is integrated into an external lubrication system using oil or grease.

What are the distinctive features of the brass cage and the C3 clearance?

The suffix M1A denotes a solid brass cage with external guidance, which guides the rollers precisely even under dynamic loads. The slightly increased radial clearance (C3) provides additional leeway for thermal expansion during operation or for tight fits on the shaft and housing. The permissible operating temperature range extends from -30 to +150 degrees, enabling the bearing to withstand the thermal demands of continuous industrial loads.
