Cylindrical Roller Bearings FAG NUP230 -E-M1

The FAG NUP230 -E-M1 cylindrical roller bearing is a single-row fixed bearing with a brass cage, designed for high radial loads, with dimensions of 150 × 270 × 45 mm.

The single-row cylindrical roller bearing NUP230 -E-M1 from FAG is designed as a fixed bearing for demanding industrial applications. Thanks to the line contact between the rollers and raceways, this design can accommodate high radial loads. With a bore diameter of 150 mm, an outer diameter of 270 mm and a width of 45 mm, this design provides precise guidance. Design engineers and maintenance personnel use this bearing to support radial loads as well as axial guidance forces in both directions.

What is the NUP230 -E-M1 cylindrical roller bearing suitable for as a fixed bearing?

Thanks to its NUP design, featuring fixed flanges on the outer ring and a flange and a loose flange disc on the inner ring, this cylindrical roller bearing functions as a fixed bearing. It absorbs primary radial loads whilst simultaneously securing the shaft axially on both sides within the housing. Typical applications include bearing arrangements in mechanical engineering subject to combined loads. As this is an open bearing without integrated seals, the lubricant can be flexibly adapted to the surrounding housing design.

What are the distinctive features of the version with a brass cage?

The -E-M1 variant is fitted with a solid brass cage that guides the rollers. Brass cages offer high dimensional stability under vibrations and shock loads and ensure smooth running of the roller row. The bearing operates within a temperature range of -30 to +150 degrees. With standard radial bearing clearance and tolerance class P0 (PN or ABEC 1), the component is suitable for standard fits. As the outer ring is designed without a groove or lubrication bore, the lubricant is supplied via the adjacent structure.
