Cylindrical Roller Bearings FAG NU2205 -E-M1

The FAG NU2205 -E-M1 cylindrical roller bearing is a single-row non-locating bearing with a brass cage, measuring 25 x 52 x 18 mm, designed for radial loads.

The NU2205 -E-M1 cylindrical roller bearing withstands high radial forces and guides the shaft within the housing. Thanks to its cylindrical rollers, this radial roller bearing provides line contact with the raceways, making it suitable for high loads. The FAG design complies with the standard tolerance class P0/PN or ABEC 1 and has a standard radial clearance.

How does the NU2205 -E-M1, as a non-locating bearing, compensate for axial displacement?

This rolling bearing functions purely as a non-locating bearing for purely radial loads. As the inner ring has no flanges and can be removed from either side, the bearing compensates for axial changes in shaft length directly within the bearing. Cylindrical roller bearings of this design are primarily used where thermally induced changes in shaft length need to be compensated for. As the bearing has an open design, it integrates directly into the lubrication circuit of the surrounding structure.

What are the advantages of the brass cage in the NU2205 -E-M1 cylindrical roller bearing?

The solid brass cage, designated M1, guides the rollers and withstands mechanical loads and vibrations. Brass exhibits favourable emergency running properties under demanding operating conditions. The bearing is designed for a temperature range of -30 to +150 degrees. During installation, it should be noted that the outer ring has no groove or lubrication bore, and lubrication must be supplied via the housing design.
