Cylindrical Roller Bearings FAG NU2206 -E-XL-M1-C3

The FAG NU2206 -E-XL-M1-C3 cylindrical roller bearing, measuring 30x62x20 mm, with a brass cage and C3 clearance, provides a heavy-duty floating bearing arrangement for high radial forces.

The FAG NU2206 -E-XL-M1-C3 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. With dimensions of 30 mm bore, 62 mm outer diameter and 20 mm width, this bearing can accommodate high radial forces. Due to its NU design, the unit functions purely as a non-locating bearing. The inner ring has no flanges and can be removed from either side, which facilitates installation. As an open bearing without an integrated seal, it is designed for operation in a lubricated housing.

Under what operating conditions is the NU2206 -E-XL-M1-C3 cylindrical roller bearing required?

This bearing is primarily used in bearing arrangements where high radial loads occur and thermally induced changes in shaft length must be compensated for. As the inner ring can move axially relative to the roller set, no internal stresses occur within the bearing system. The brass cage guides the cylindrical rollers precisely and is particularly suitable for applications involving high speeds and environments subject to high levels of vibration.

What is the function of the brass cage and the C3 radial clearance in this bearing?

The combination of the brass cage and the increased C3 radial clearance determines the specific operating characteristics of this design. The solid brass cage is characterised by high mechanical strength and withstands high accelerations and vibrations. The slightly increased C3 bearing clearance compensates for radial play when temperature differences occur between the shaft and housing during operation, or when tight fits are specified. The bearing operates within a temperature range of -30 to +150 degrees and complies with the standard tolerance class P0/ABEC 1.
