Cylindrical Roller Bearings FAG NUP2309 -E-XL-TVP2

The NUP2309 -E-XL-TVP2 cylindrical roller bearing from FAG Wälzlager, measuring 45 × 100 × 36 mm, serves as a fixed bearing for high radial loads and axial guidance on both sides.

The NUP2309 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing of the NUP design. Thanks to the line contact between the cylindrical rollers and the raceways, this bearing can accommodate high radial forces. Featuring two fixed flanges on the outer ring and a fixed flange with a loose flange disc on the inner ring, this design secures the shaft axially in both directions. The open design is intended for lubricated installations.

In which installation situations does the NUP2309 -E-XL-TVP2 cylindrical roller bearing function as a fixed bearing?

This cylindrical roller bearing is used when a bearing arrangement must accommodate not only high radial forces but also alternating axial forces. Such requirements arise in shaft support arrangements with guidance on both sides within the housing. The NUP design acts as a fully-fledged fixed bearing, meaning that no separate axial support from the opposite direction is required. As the outer ring is designed without a groove or lubrication bore, the lubricant is supplied via the surrounding housing space.

What are the distinctive features of the TVP2 polyamide cage design?

The suffix TVP2 denotes a solid window cage made of polyamide. This plastic cage reduces the moving mass of the rolling elements and dampens vibrations during operation. The bearing is designed for a temperature range of -30 to +120 degrees and has standard radial clearance. With manufacturing tolerances to tolerance class P0 or ABEC 1, the design accommodates standard installation tolerances in mechanical engineering.
