Cylindrical Roller Bearings FAG NJ2313 -E-XL-TVP2-C3

The FAG NJ2313 -E-XL-TVP2-C3 cylindrical roller bearing (65x140x48 mm) is designed as a single-row support bearing for heavy radial loads with single-sided axial guidance.

The FAG NJ2313 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing with a bore diameter of 65 mm, an outer diameter of 140 mm and a width of 48 mm. Compared to balls, the cylindrical rollers provide line contact, which enables high radial forces to be accommodated whilst maintaining a compact design. In the NJ version, the rolling bearing has two fixed flanges on the outer ring and one fixed flange on the inner ring. This design allows the bearing to accommodate additional unidirectional axial forces, whilst the inner ring remains removable for installation.

In which bearing arrangements does the NJ2313 -E-XL-TVP2-C3 cylindrical roller bearing act as a support bearing?

This design is primarily used in bearing arrangements subject to very high radial forces and axial guidance forces from a single direction. The support bearing design allows a shaft to be guided axially in one direction, whilst the counter-bearing accommodates thermal linear expansion.

As an open bearing without integrated seals, the component is fitted directly into a lubricated housing. This allows the lubricant to reach the rolling elements and raceways of the bearing assembly unhindered.

What role do the polyamide cage and C3 bearing clearance play in the selection process?

The designation TVP2 stands for a dimensionally stable polyamide cage, which ensures quiet running and low friction. In conjunction with the increased radial clearance (C3), the bearing compensates for operational heating or tight fits. This reduces the risk of the rolling elements becoming stressed during operation.

The permissible temperature range extends from –30 to +120 degrees Celsius and is determined by the cage material. As the outer ring has no groove or lubrication bore, lubricant is supplied axially via the installation environment. With the standard tolerance P0 or ABEC 1, the bearing meets standard industrial accuracy requirements.
