Cylindrical Roller Bearings FAG NJ309 -E-XL-TVP2

The FAG nj309-e-xl-tvp2 cylindrical roller bearing offers high radial load-carrying capacity with a lightweight polyamide cage, with an outer diameter of 100 mm and a width of 25 mm.

The FAG Wälzlager cylindrical roller bearing nj309-e-xl-tvp2 is designed as an open roller bearing for demanding industrial applications. Thanks to its cylindrical rollers, this design can withstand heavy radial loads. The component features a cylindrical bore and operates with standard radial clearance. Thanks to its open design, the bearing can be integrated directly into existing lubrication circuits, whilst the polyamide cage ensures smooth running of the rolling elements.

For which loads is the nj309-e-xl-tvp2 cylindrical roller bearing suitable?

Design engineers and maintenance personnel primarily use this bearing design at bearing locations subject to significant radial loads. The bearing is used on rotating shafts that require a robust radial support. The NJ design features a flange on the inner ring, enabling it to accommodate axial forces in one direction in addition to the main radial load. Furthermore, this design accommodates thermal length changes in the shaft, provided the surrounding structure is appropriately designed to cope with them.

What advantages does the polyamide cage offer during operation?

The integrated polyamide cage guides the cylindrical rollers precisely and reduces the weight of the rotating components. Plastics effectively dampen vibrations during operation, which minimises noise and improves running characteristics. When using the bearing, the permissible temperature range of -30 to +120 °C must be observed, as this is determined by the cage material. As no sealing washers are fitted, you should ensure effective external sealing against contamination in the surrounding assembly.
