Cylindrical Roller Bearings FAG NJ310 -E-XL-TVP2-C3

The FAG NJ310 -E-XL-TVP2-C3 cylindrical roller bearing (50x110x27 mm) can accommodate high radial loads and serves as a support bearing with single-sided axial guidance.

The FAG NJ310 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row rolling bearing designed for demanding industrial applications. Thanks to the line contact of the cylindrical rollers, this design can handle high radial forces. Designed as an open bearing, the component can be flexibly integrated into existing lubrication circuits. The lightweight polyamide cage ensures smooth running. With key dimensions of 50 mm bore diameter, 110 mm outer diameter and 27 mm width, the model complies with current standardisation in accordance with tolerance class P0/PN.

In which installation scenarios is the NJ310 -E-XL-TVP2-C3 used as a support bearing?

In bearing arrangements subject to high radial forces, this design is used to accommodate heavy radial loads. The NJ design acts as a support bearing: it guides the shaft in one axial direction whilst compensating for changes in the shaft’s length in the opposite direction. This allows thermal longitudinal expansion to be accommodated without internal stresses. In combination with a suitable mating bearing, designers can thus create a statically determined bearing arrangement for machine components subject to thermal stress.

What is the function of the polyamide cage and the C3 bearing clearance in this design?

The increased radial clearance (C3) compensates for dimensional changes caused by tight fits on the shaft and housing or by temperature differences during operation. This helps to prevent the rolling elements from becoming jammed. The polyamide cage (TVP2) is characterised by its low mass and damping properties. This makes the bearing suitable for operating temperatures ranging from –30 to +120 degrees. The classification in tolerance class ABEC 1 or P0 defines the standardised dimensional accuracy for general mechanical engineering.
