Cylindrical Roller Bearings FAG NU316 -E-XL-TVP2-C3

The FAG NU316 -E-XL-TVP2-C3 cylindrical roller bearing, with an 80 mm bore, offers high radial load-carrying capacity and axial compensation when used as a non-locating bearing.

The NU316 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for high radial loads. Thanks to the line contact of the cylindrical rollers, the design can withstand high loads. With dimensions of 80 mm inner diameter, 170 mm outer diameter and 39 mm width, the NU design functions purely as a non-locating bearing. The inner ring has no flanges and can be removed from either side, which facilitates the separate assembly of the inner and outer rings.

How does the NU316 -E-XL-TVP2-C3 compensate for axial displacement as a non-locating bearing?

This non-locating bearing is suitable for mounting positions subject to purely radial loads, where thermally induced changes in shaft length must be compensated for without restriction. The outer ring guides the roller set between two fixed flanges, whilst the shaft can move axially relative to the housing. As this is an open bearing without an integrated seal, external sealing of the bearing location and integration into a lubrication system are required.

What are the benefits of the polyamide cage and the C3 clearance?

The TVP2 version features a polyamide cage, which ensures quiet operation and keeps the weight of the rotating components low. The C3 designation indicates a slightly increased radial clearance compared with the standard version. This increased clearance prevents the bearing from becoming stressed due to temperature differences between the shaft and housing or in the case of tight fits. The bearing is designed for a temperature range of -30 to +120 degrees and complies with tolerance class P0/PN or ABEC 1.
