Cylindrical Roller Bearings FAG NJ224 -E-XL-TVP2-C3

The FAG NJ224 -E-XL-TVP2-C3 cylindrical roller bearing (120x215x40 mm) withstands high radial loads and functions as a support bearing with axial displacement.

The NJ224 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row rolling bearing from FAG designed for demanding industrial applications. Thanks to the modified line contact of the cylindrical rollers, this design can withstand significantly higher radial forces than point-contact ball bearings. This version has a bore of 120 mm, an outer diameter of 215 mm and a width of 40 mm. As an open bearing, the component can be specifically integrated into existing oil or grease lubrication systems.

What is the NJ224 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?

This rolling bearing is primarily used for high radial loads and unilateral axial forces. As an NJ design, the bearing has two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows it to function as a support bearing: it guides the shaft in one axial direction whilst permitting axial displacement in the opposite direction. This compensates for thermal expansion of the shaft within the housing without generating stress.

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

The designation TVP2 indicates a polyamide cage that guides the cylindrical rollers. The material operates quietly and is suitable for operating temperatures ranging from –30 to +120 degrees Celsius. The increased bearing clearance class C3 provides additional radial clearance in the bearing. This feature compensates for thermal expansion caused by high operating temperatures or tight fit oversizes on the shaft and housing, ensuring that the rolling elements always roll freely without jamming.
