Cylindrical Roller Bearings FAG NU222 -E-XL-TVP2

The NU222 -E-XL-TVP2 cylindrical roller bearing from FAG is a single-row non-locating bearing with a polyamide cage, designed for shaft diameters of 110 mm under radial loads.

The NU222 -E-XL-TVP2 cylindrical roller bearing from FAG Wälzlager is designed to withstand high forces as a radial roller bearing. With key dimensions of 110 mm bore, 200 mm outside diameter and 38 mm width, this design is suitable for demanding industrial applications. As the rollers have line contact, the bearing can withstand greater transverse forces than point-contact ball bearings. The inner ring has no flanges and can be removed from either side, which facilitates installation work on the surrounding structure.

What is the NU222 -E-XL-TVP2 cylindrical roller bearing suitable for?

This cylindrical roller bearing is primarily used where high radial loads are present and the bearing serves purely as a non-locating bearing. The design of the NU series compensates for thermally induced changes in shaft length directly between the rollers and the cylindrical inner ring raceway. As the bearing does not accommodate any axial forces, this type is usually combined with a separate fixed bearing.

What is the function of the polyamide cage in the NU design?

The polyamide cage (TVP2) guides the cylindrical rolling elements with low vibration and reduced noise. Compared with solid metal cages, the lightweight plastic material reduces the bearing’s mass, which has a positive effect on start-up behaviour. When designing the bearing, the permissible temperature range of -30 to +120 degrees Celsius must be taken into account. As this is an open bearing without an integrated seal, lubrication and external sealing elements must be adapted to the specific operating environment.
