Cylindrical Roller Bearings FAG NUP208 -E-XL-TVP2

The FAG NUP208 -E-XL-TVP2 cylindrical roller bearing, as a single-row fixed bearing, combines a high radial load capacity with axial guidance on both sides and a 40 mm bore.

The FAG NUP208 -E-XL-TVP2 cylindrical roller bearing is used where heavy radial loads occur and the shaft must be guided axially in both directions. Due to the line contact between the rollers and raceways, this single-row roller bearing is suitable for high loads compared to point-contact ball bearings of the same dimensions. With main dimensions of 40 mm inner diameter and 80 mm outer diameter, as well as a width of 18 mm, this open bearing meets the demanding requirements of general mechanical engineering.

What functions does the NUP208 -E-XL-TVP2 cylindrical roller bearing perform in mechanical engineering?

This fixed bearing is designed to accommodate heavy radial loads whilst simultaneously limiting axial shaft play. It is used wherever shafts need to be supported and axially fixed, whilst thermal linear expansion is compensated for by a separate floating bearing. As this is an open design without integrated seals, an external housing seal provides protection against contaminants and moisture. Lubrication is carried out using an external lubrication system with oil or grease, depending on the application.

What is the function of the NUP fixed bearing design with a polyamide cage?

The NUP design features two fixed flanges on the outer ring, as well as one fixed flange and one loose flange disc on the inner ring. This enables the bearing to absorb axial forces alternately in both directions and to guide the shaft longitudinally. The integrated TVP2 window cage made of polyamide guides the rollers quietly and is characterised by its low weight. The component meets tolerance class P0 (ABEC 1) with standard radial clearance and is designed for operating temperatures ranging from -30 to +120 degrees.
