Cylindrical Roller Bearings FAG NU209 -E-XL-K-TVP2-C3

The FAG NU209 -E-XL-K-TVP2-C3 cylindrical roller bearing offers high radial load-carrying capacity with a 45 mm bore, a tapered seat and increased C3 clearance.

The FAG NU209 -E-XL-K-TVP2-C3 cylindrical roller bearing is a single-row non-locating bearing for applications subject to high radial loads. With key dimensions of a 45 mm bore diameter, 85 mm outer diameter and 19 mm width, the NU design compensates for axial length changes in the shaft directly within the bearing without any constraint. The inner ring, which can be removed from both sides, simplifies the separate assembly of both bearing rings. As an open rolling bearing without an integrated seal, the lubrication can be precisely tailored to the specific operating environment.

What loads can the NU209 -E-XL-K-TVP2-C3 cylindrical roller bearing accommodate?

The bearing unit is used in applications where purely radial forces need to be supported. As the inner ring has no fixed flanges, the shaft moves with minimal friction relative to the housing during thermal expansion. The integrated polyamide cage is characterised by its low weight and the elastic guidance it provides for the rolling elements. The bearing is designed for a temperature range of -30 to +120 degrees.

What are the special features of the tapered bore and C3 clearance?

The tapered bore with a taper ratio of 1:12 allows for precise mounting on tapered shaft seats or using a shrink sleeve. This enables you to precisely set the desired fit and the remaining operating clearance via the axial slide-on travel. In conjunction with the slightly increased radial clearance (C3), the bearing compensates for operational heating or tight fits without the rollers seizing up. The component complies with standard tolerance class P0 (ABEC 1) and has an outer ring without a lubrication groove.
