Cylindrical Roller Bearings FAG NU219 -E-M1

The FAG NU219 -E-M1 cylindrical roller bearing, with a 95 mm bore, offers high radial load-carrying capacity and axial displacement capability when used as a non-locating bearing.

This single-row NU219 -E-M1 cylindrical roller bearing from FAG is primarily designed to accommodate high radial forces. Thanks to the line contact between the rollers and raceways, the design can withstand high loads. As an open bearing without an integrated seal, the unit is designed for lubrication systems using oil or grease. The permissible temperature range extends from –30 to +150 degrees Celsius and covers demanding thermal conditions in mechanical engineering.

What is the NU219 -E-M1 cylindrical roller bearing used for?

The bearing unit absorbs high radial forces in rotating systems. As the inner ring is flangeless on both sides and therefore removable, the bearing functions purely as a non-locating bearing. It compensates for thermally induced changes in shaft length without constraint within the rolling elements. The outer ring has no lubrication groove or bore, so lubricant is supplied via the housing design or the open end face.

What advantages do the brass cage and NU design offer during assembly?

The brass cage guides the rolling elements precisely and withstands mechanical stresses and vibrations. The standard radial bearing clearance contributes to stable running behaviour under normal operating conditions. Thanks to tolerance class P0/PN (corresponding to ABEC 1), the bearing meets common industry standards. The separate assembly of the inner and outer rings facilitates press-fitting and installation into the bearing housing.
