Cylindrical Roller Bearings FAG NU211 -E-XL-TVP2

The NU211 -E-XL-TVP2 cylindrical roller bearing from FAG, measuring 55x100x21 mm, offers high radial load-carrying capacity as a separable idler bearing for demanding industrial applications.

The NU211 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing from FAG Wälzlager with a cylindrical bore. With a bore of 55 mm, an outer diameter of 100 mm and a width of 21 mm, this design is primarily designed to withstand high radial loads. As an open bearing, it can be flexibly integrated into existing lubrication systems. It is manufactured to tolerance class P0/PN or ABEC 1, meaning the bearing meets the standard for industrial mechanical engineering.

When is the NU211 -E-XL-TVP2 design recommended?

This version is primarily used where bearings need to compensate for thermal length changes in the shaft. As the NU design is conceived as a pure non-locating bearing, the inner ring has no flanges and can be removed from either side. Axial movements occur freely within the raceway between the rollers and the ring. It is primarily used in shaft bearings where precise radial guidance is required and axial forces are supported separately by a fixed bearing.

What advantages does the TVP2 polyamide cage offer in this bearing?

The suffix TVP2 denotes a polyamide cage that precisely guides the cylindrical rollers. The material dampens running noise and reduces friction during operation. When using this bearing, the permissible temperature range of –30 to +120 degrees must be taken into account, as plastics are more sensitive to overheating than metallic materials. The bearing has a standard radial clearance, which promotes stable concentricity at normal operating temperatures and with standard shaft fits.
