Cylindrical Roller Bearings FAG NU317 -E-XL-TVP2

The FAG NU317 -E-XL-TVP2 cylindrical roller bearing withstands high radial loads whilst maintaining compact dimensions of 85 × 180 × 41 mm in industrial applications.

The NU317 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing for industrial applications subject to significant radial loads. Thanks to the line contact between the rollers and the hardened raceways, this design offers high rigidity. Designed as an open bearing, the unit operates without integrated mechanical seals and can be integrated directly into existing housing lubrication systems. The bearing is manufactured by FAG and complies with tolerance class P0/PN or ABEC 1.

In which installation situations is the NU317 -E-XL-TVP2 non-locating bearing required?

The NU design is primarily suitable for bearing locations where purely radial forces act and axial displacement of the shaft must be compensated for by the design. Designed as a non-locating bearing, the outer ring has two fixed flanges, whilst the inner ring is flangeless and removable from both sides. This allows the bearing arrangement to provide a non-constrained axial length compensation within the bearing itself. Designs in general mechanical engineering utilise this property to accommodate thermal expansion without additional internal forces.

What is the function of the polyamide cage in the TVP2 design?

The designation ‘TVP2’ indicates a solid, open-type cage made of polyamide. This cage guides the cylindrical rolling elements with low friction and, due to its low weight, reduces inertial forces during changes in rotational speed. The permissible operating range extends from –30 to +120 degrees Celsius. The standard radial bearing clearance promotes balanced operating clearance when the bearing is installed, provided that the shaft and housing bore comply with standardised fit specifications.
