Cylindrical Roller Bearings FAG NJ2216 -E-XL-TVP2-C3

The FAG NJ2216 -E-XL-TVP2-C3 cylindrical roller bearing, measuring 80x140x33 mm, combines a high radial load capacity with a single-sided axial guidance function.

This single-row cylindrical roller bearing, model NJ2216 -E-XL-TVP2-C3, is manufactured by FAG and is designed as an open roller bearing without seals. With a bore of 80 mm, an outside diameter of 140 mm and a width of 33 mm, this design can accommodate substantial radial loads. Due to its open design, lubricant reaches the raceways and rolling elements unimpeded; for this reason, the bearing should be integrated into a protected housing with external sealing.

What is the NJ2216 -E-XL-TVP2-C3 cylindrical roller bearing suitable for as a support bearing?

The NJ version functions as a support bearing during operation. The outer ring has two fixed flanges, whilst the inner ring has a single flange and is removable from one side. This enables the bearing to accommodate not only high radial forces but also axial guidance forces from one direction, whilst retaining axial displacement in the opposite direction. This feature facilitates the assembly of separate rings and specifically compensates for temperature-induced changes in shaft length.

What are the advantages of a polyamide cage and C3 clearance?

The integrated polyamide cage ensures smooth guidance of the cylindrical rollers whilst maintaining a low mass. The assembly is designed for a temperature range of –30 to +120 degrees. The C3 designation indicates a slightly increased radial bearing clearance. This increased clearance between the rollers and raceways counteracts seizing if operational heating or tight fits reduce the radial operating clearance during operation.
