Cylindrical Roller Bearings FAG NU203 -E-XL-TVP2

The NU203 -E-XL-TVP2 cylindrical roller bearing from FAG Wälzlager is a support bearing measuring 17x40x12 mm, offering a compact guide for high radial loads.

The NU203 -E-XL-TVP2 cylindrical roller bearing is a single-row roller bearing for industrial applications subject to purely radial loads. Thanks to the line contact between the rollers and raceways, this design can accommodate high radial forces. With an inside diameter of 17 mm, an outside diameter of 40 mm and a width of 12 mm, the component fits precisely into compact housing designs. It has standard radial clearance and operates to tolerance class P0.

What is the NU203 -E-XL-TVP2 cylindrical roller bearing suitable for in machinery?

The NU203 -E-XL-TVP2 cylindrical roller bearing typically functions as a non-locating bearing within the bearing system. As the inner ring has no flanges and can be removed from both sides, the bearing compensates for axial length changes in the shaft without constraint, directly within the rolling element set. This characteristic is specifically utilised in designs where shafts expand thermally during operation. Furthermore, the separable design facilitates the separate assembly of the inner and outer rings.

What advantages does the polyamide cage in this design offer?

The integrated polyamide cage guides the cylindrical rollers with low friction and promotes smooth running. The material dampens shocks within the rolling element set and is designed for operation in a temperature range of –30 to +120 degrees Celsius. As this is an open bearing without seals and without a groove or lubrication bore in the outer ring, the lubricant is supplied via the surrounding machine housing. Suitable housing seals protect the system against the ingress of particles.
