Cylindrical Roller Bearings FAG NU322 -E-XL-TVP2

The FAG NU322 -E-XL-TVP2 cylindrical roller bearing, measuring 110 × 240 × 50 mm, provides a robust floating bearing arrangement for high radial forces in mechanical engineering.

The NU322 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing from FAG without a seal. With a bore of 110 mm, an outer diameter of 240 mm and a width of 50 mm, this open bearing is primarily designed to accommodate high radial forces. This design features standard radial clearance and complies with tolerance class P0/PN or ABEC 1. It is suitable for operating temperatures ranging from -30 to +120 degrees Celsius.

What is the NU322 -E-XL-TVP2 cylindrical roller bearing suitable for in operation?

This single-row cylindrical roller bearing is particularly suitable for bearing arrangements subject to predominantly radial loads, where axial length changes in the shaft must be compensated for. In designs with a separate fixed and floating bearing arrangement, the NU design serves as the floating bearing. As the inner ring can be removed from both ends, the bearing compensates for operational thermal expansion of the shaft without constraint within the raceway. Pure radial loads are evenly transferred by the cylindrical rollers via line contact into the surrounding structure.

What advantages does the polyamide cage offer in the NU design?

The integrated polyamide cage guides the rolling elements with low friction and contributes to smooth running within a temperature range of –30 to +120 degrees Celsius. At the same time, the separable design of the NU series simplifies assembly: the inner ring and outer ring, together with the roller set, can be fitted separately onto the shaft and housing. As the outer ring has no groove or lubrication bore and the bearing is of open design, you can adjust the lubricant supply via the bearing housing.
