Cylindrical Roller Bearings FAG NU2220 -E-XL-M1-C3

The FAG NU2220 -E-XL-M1-C3 cylindrical roller bearing, with dimensions of 100 × 180 × 46 mm, is suitable for use as a support bearing for high radial loads.

The single-row cylindrical roller bearing NU2220 -E-XL-M1-C3 from FAG, as a radial rolling bearing, can withstand high forces. With a bore of 100 mm, an outer diameter of 180 mm and a width of 46 mm, it is typically used for shaft guidance in gearboxes and industrial plant. As an open idler bearing, it allows for axial displacement compensation within the bearing itself, as the flangeless inner ring is designed to be removable from both sides.

What is the NU2220 -E-XL-M1-C3 cylindrical roller bearing suitable for?

This roller bearing is primarily used where purely radial loads occur under demanding conditions. Typical applications can be found in general mechanical engineering as well as in bearing arrangements subject to high radial forces. Thanks to its solid brass cage, the component is also suitable for operating conditions involving vibrations or acceleration forces. As the outer ring has two fixed flanges and the inner ring is flangeless, the bearing easily compensates for thermal length changes in the shaft.

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

The version with the suffix M1 features a solid brass cage, which ensures the smooth guidance of the cylindrical rollers. The C3 designation indicates a slightly increased radial clearance compared with the standard version. This additional clearance reduces the risk of stress in the rolling elements should temperature differences arise between the inner and outer rings during operation, or where tight fits are specified. The bearing is designed for operating temperatures ranging from -30 to +150 degrees.
