Cylindrical Roller Bearings FAG NJ208 -E-XL-M1-C3

The FAG NJ208 -E-XL-M1-C3 cylindrical roller bearing, with dimensions of 40x80x18 mm, can accommodate high radial forces as well as single-sided axial loads.

The NJ208 -E-XL-M1-C3 cylindrical roller bearing is a single-row radial roller bearing manufactured by FAG. In the NJ design, the outer ring has two solid flanges, whilst the inner ring has one solid flange. This design enables the bearing to accommodate radial forces and support axial forces from one direction. The open bearing has the following main dimensions: 40 mm bore, 80 mm outer diameter and 18 mm width.

What is the NJ208 -E-XL-M1-C3 cylindrical roller bearing suitable for?

This cylindrical roller bearing is primarily used as a support bearing in bearing arrangements subject to high radial loads and single-sided axial guidance. As the inner ring is removable from one side, the shaft can be guided axially in one direction, whilst axial displacement in the opposite direction is permitted. This design therefore compensates for thermal length changes in the shaft. Compared to point contact, the line contact of the cylindrical rollers ensures a high radial load-carrying capacity with a rigid mounting.

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

The version with the suffix combination M1 features a solid brass cage which guides the rollers and retains its dimensional stability even under dynamic loads. The increased radial clearance C3 provides additional radial clearance between the rollers and raceways. This clearance reduces the risk of stress build-up in the bearing should temperature differences arise between the shaft and housing during operation, or where tight fits are specified. For the open bearing, a temperature range of -30 to +150 degrees is permissible.
