Cylindrical Roller Bearings FAG NU312 -E-XL-TVP2-C3

The FAG NU312 -E-XL-TVP2-C3 cylindrical roller bearing, with a 60 mm bore, withstands high radial loads and compensates for axial length changes without binding.

The NU312 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. Thanks to the line contact between the rollers and raceways, the design can withstand high radial loads. Designed as a non-locating bearing, the outer ring has two fixed flanges, whilst the inner ring remains flangeless and can be removed from both sides. This separability facilitates assembly and maintenance in mechanical engineering.

In which installation situations does the NU312 -E-XL-TVP2-C3 cylindrical roller bearing prove its worth?

This cylindrical roller bearing is primarily used where high radial load capacity combined with a free-end bearing function is required. As the inner ring has no flanges, the bearing compensates for thermally induced changes in shaft length directly within the bearing. It is suitable for applications wherever axial displacement needs to be accommodated without inducing stress. Thanks to its open design without seals, the bearing can be integrated directly into on-site oil or grease lubrication systems.

What properties do the polyamide cage and C3 bearing clearance offer?

The designation TVP2 indicates a solid polyamide cage which guides the rollers and promotes low-friction operation. In combination with the slightly increased radial bearing clearance (C3), the radial bearing clearance is maintained even when operational heating or tight fits reduce the clearance. An operating temperature range of -30 to +120 degrees is permitted. The design must include an external housing seal to protect against the ingress of dirt.
