Cylindrical Roller Bearings FAG NU205 -E-M1

The NU205 -E-M1 single-row cylindrical roller bearing, with a brass cage and main dimensions of 25 × 52 × 15 mm, serves as a separable support bearing for high radial loads.

The NU205 -E-M1 cylindrical roller bearing from FAG Wälzlager is an open, single-row radial roller bearing for mechanical engineering. With a bore of 25 mm, an outside diameter of 52 mm and a width of 15 mm, this design can accommodate high radial loads. The brass cage guides the cylindrical rollers precisely and is suitable for operating temperatures ranging from –30 to +150 degrees. The bearing complies with tolerance class P0/PN or ABEC 1 and has standard radial clearance for normal operating conditions.

What is the NU205 -E-M1 cylindrical roller bearing suitable for in industrial plant?

In industrial drives and shaft guides, this design is suitable for bearing arrangements subject to purely radial loads. As the outer ring has solid flanges on both sides, whilst the inner ring is flangeless, the unit functions as a non-locating bearing. The bearing compensates for axial changes in shaft length caused by thermal effects without any forced alignment. This design is used in applications where a separate fixed bearing provides the axial guidance.

What are the distinctive features of the brass cage in the NU205 -E-M1 cylindrical roller bearing?

The brass cage (designation M1) guides the rolling elements reliably even in the presence of vibrations or fluctuating speeds. Furthermore, the open design without an integrated seal allows for direct lubrication via the machine’s lubrication system. As the inner ring can be removed from both sides, mount the inner and outer rings separately onto the shaft and housing. An external housing seal protects the open rolling system from the ingress of dirt.
