Cylindrical Roller Bearings FAG NJ203 -E-XL-TVP2-C3

The FAG NJ203 -E-XL-TVP2-C3 cylindrical roller bearing, measuring 17x40x12 mm, with a polyamide cage and C3 clearance, offers a high-load-capacity solution for radial guidance.

The NJ203 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing designed for demanding mechanical assemblies. Thanks to the line contact between the rollers and raceways, this design can withstand high radial loads. The manufacturer, FAG, equips this variant with the increased radial clearance C3 and a lightweight polyamide cage. As an open roller bearing without sealing washers, the unit integrates seamlessly into existing lubrication systems.

What is the NJ203 -E-XL-TVP2-C3 cylindrical roller bearing suitable for as a support bearing?

This roller bearing acts as a support bearing in gearboxes and shaft guides. It guides the shaft in the radial direction and, thanks to two fixed flanges on the outer ring and one fixed flange on the inner ring, absorbs axial forces from one direction. The inner ring can be removed from one side, allowing axial displacements of the shaft in the opposite direction to be compensated for. The bearing serves to compensate for thermal length changes in the supported shaft.

What is the function of the polyamide cage and the C3 clearance during operation?

The version with the suffix TVP2 features a dimensionally stable polyamide cage, which guides the rollers and keeps the moment of inertia of the bearing assembly low. In combination with the slightly increased radial clearance (C3), this design helps to prevent the rolling elements from becoming stressed due to oversize fits or heating. The permissible temperature range extends from –30 to +120 degrees Celsius, enabling a wide variety of operating conditions.
