Cylindrical Roller Bearings FAG NU315 -E-XL-TVP2-C3

The FAG NU315 -E-XL-TVP2-C3 cylindrical roller bearing, with a 75 mm bore and C3 clearance, offers high radial load-carrying capacity when used as a non-locating bearing.

The FAG NU315 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. With an inner diameter of 75 mm, an outer diameter of 160 mm and a width of 37 mm, this design can withstand considerable radial forces. Designed as an open bearing, the unit can be flexibly integrated into existing lubrication systems. The polyamide cage (TVP2) ensures smooth running at operating temperatures ranging from –30 to +120 degrees Celsius.

What is the NU315 -E-XL-TVP2-C3 cylindrical roller bearing suitable for as a non-locating bearing?

In shaft mountings, this bearing primarily serves as a conventional idler bearing to support purely radial loads. As the inner ring has no flanges and can be removed from both sides, the design compensates for axial length changes in the shaft directly within the bearing. It is primarily used in applications involving thermally induced length changes and high radial forces. The tolerance class P0 or ABEC 1 provides a defined standard for industrial mechanical engineering.

What advantages do the polyamide cage and C3 bearing clearance offer in this design?

The version with the suffix TVP2 features a lightweight polyamide cage, which reduces inertial forces during operation and promotes low-noise rolling. In combination with the slightly increased radial clearance (C3), the component helps to prevent the rollers from seizing up when heated or in tight fits. The outer ring has no groove or lubrication bore, which enhances the strength of the outer raceway.
