Cylindrical Roller Bearings FAG NJ2214 -E-XL-TVP2

The FAG NJ2214 -E-XL-TVP2 cylindrical roller bearing, measuring 70x125x31 mm, offers a high radial load capacity and functions as a support bearing with single-sided axial guidance.

The single-row cylindrical roller bearing NJ2214 -E-XL-TVP2 is designed for demanding industrial applications in which heavy radial forces act on the shaft. Thanks to the line contact between the rollers and raceways, this FAG roller bearing can absorb considerable forces. With key dimensions of a 70 mm bore, 125 mm outer diameter and 31 mm width, this open bearing meets standard industrial requirements in gearbox and mechanical engineering.

What functions does the NJ2214 -E-XL-TVP2 cylindrical roller bearing perform as a support bearing?

This roller bearing primarily absorbs high radial loads and limits axial displacement of the shaft in one direction. As a support bearing, the NJ version features two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, the design absorbs axial forces from one direction, whilst compensating for thermally induced length changes in the opposite direction. Typical applications include shaft mountings with single-sided guidance and high radial forces.

What are the characteristics of the polyamide cage and the NJ design?

The polyamide cage (TVP2) guides the cylindrical rollers precisely and is characterised by its low weight and smooth running. The open design requires a clean installation environment and external lubrication, as the outer ring is designed without a groove or lubrication bore. For installation purposes, the inner ring can be removed from one side, allowing both bearing rings to be fitted separately onto the shaft and housing. The bearing is suitable for a temperature range of -30 to +120 degrees.
