Cylindrical Roller Bearings FAG NU318 -E-XL-TVP2-C3

The FAG NU318 -E-XL-TVP2-C3 cylindrical roller bearing, with dimensions of 90 × 190 × 43 mm, provides a high-load-capacity free-running bearing with increased C3 clearance.

The FAG NU318 -E-XL-TVP2-C3 cylindrical roller bearing, as a single-row roller bearing, can withstand high radial loads. Thanks to the line contact between the rollers and raceways, this rolling bearing exhibits high rigidity. The NU design is intended purely as a floating bearing, so that changes in shaft length can be compensated for directly within the bearing. The polyamide cage guides the rolling elements with minimal vibration and ensures smooth running during operation.

What functions does the NU318 -E-XL-TVP2-C3 cylindrical roller bearing fulfil as a non-locating bearing?

This rolling bearing is suitable for bearing arrangements subject to high radial loads, where axial changes in shaft length must be compensated for. As the inner ring can be removed from both sides, the bearing can be fitted separately onto the shaft and housing. This ability to be dismantled facilitates maintenance work and inspections. As a non-locating bearing, the NU design absorbs purely radial forces and allows the shaft axial movement due to thermal expansion.

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

The version with the suffix TVP2 features a lightweight polyamide cage, which helps to reduce friction and offers emergency running properties. The permissible temperature range is from –30 to +120 degrees. The increased radial clearance (C3) helps to ensure that sufficient operating clearance is maintained even when the bearing heats up or in the case of tight fits. As this is an open bearing without a seal, the lubricant and external housing seal are selected to suit the operating environment.
