Cylindrical Roller Bearings FAG NU2308 -E-XL-TVP2

The FAG NU2308 -E-XL-TVP2 cylindrical roller bearing, measuring 40x90x33 mm, is a free-running bearing with a polyamide cage designed for high radial loads.

The single-row cylindrical roller bearing NU2308 -E-XL-TVP2 from FAG, as a radial roller bearing, accommodates high radial forces whilst maintaining a compact design. With a bore of 40 mm, an outside diameter of 90 mm and a width of 33 mm, this component is used in mechanical and plant engineering. Thanks to the line contact between the cylindrical rollers and the raceways, this roller bearing withstands heavy loads and ensures rigid guidance of the shaft.

When is the NU2308-E-XL-TVP2 cylindrical roller bearing used as a non-locating bearing?

This design is primarily used in bearing arrangements that transmit purely radial forces and must compensate for axial length changes in the shaft without constraint. As a NU-type non-locating bearing, the roller bearing has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This design allows for axial displacement between the two rings, ensuring that temperature-induced changes in the shaft’s length do not cause harmful stresses in the rolling element set.

What are the characteristics of the TVP2 polyamide cage?

The designation TVP2 indicates a polyamide cage that guides the cylindrical rollers. The material reduces the cage’s weight, minimises inertial forces during acceleration and is characterised by its damping properties. The permissible temperature range extends from -30 to +120 degrees. The open bearing has standard radial clearance and a tolerance class of P0/PN or ABEC 1, and requires external lubrication and sealing.
