Cylindrical Roller Bearings FAG NU214 -E-XL-M1-C3

The FAG NU214 -E-XL-M1-C3 cylindrical roller bearing, measuring 70 x 125 x 24 mm and featuring a brass cage, offers a robust free-running bearing solution for high radial loads.

The FAG NU214 -E-XL-M1-C3 cylindrical roller bearing is a single-row rolling bearing with a 70 mm bore, 125 mm outer diameter and 24 mm width. As it is designed as a loose bearing, the inner ring can be removed from both sides, which facilitates the separate assembly of the shaft and housing. Designed as an open bearing, it operates within a temperature range of -30 to +150 degrees. Design engineers and maintenance technicians appreciate the combination of robust assembly guidance and the defined tolerance class P0/PN (ABEC 1) for demanding industrial applications.

What is the NU214 -E-XL-M1-C3 cylindrical roller bearing suitable for?

This cylindrical roller bearing primarily absorbs high radial forces and compensates for axial length changes in the shaft directly within the bearing. Typical applications are found in general mechanical engineering in shaft mountings where thermal expansion occurs. As the outer ring has fixed flanges and the inner ring is flangeless, the shaft can move freely relative to the housing. For designs with fixed axial guides, this non-locating bearing provides a reliable operational basis.

What advantages do the brass cage and C3 clearance offer in this design?

The integrated brass cage guides the cylindrical rollers precisely and withstands severe vibrations as well as high mechanical loads. In combination with the slightly increased radial clearance (C3), the bearing counteracts jamming should temperature differences arise between the inner and outer rings during operation or where tight fits are specified. As the bearing is of an open design, the bearing housing requires an external seal and a suitable lubricant to prevent the ingress of dirt particles.
