Cylindrical Roller Bearings FAG NUP211 -E-M1

The FAG NUP211 -E-M1 cylindrical roller bearing, with a 55 mm bore and a brass cage, provides a robust fixed mounting capable of withstanding high radial forces.

The NUP211 -E-M1 cylindrical roller bearing is designed as a single-row rolling bearing with a cylindrical bore. Thanks to the line contact between the rollers and raceways, this design can accommodate high radial loads. The main dimensions are 55 mm internal diameter, 100 mm external diameter and 21 mm width. The bearing is manufactured to the standard tolerance class P0 or ABEC 1 and with standard radial clearance, which enables a precise fit in standardised housings.

In which installation scenarios does the NUP211-E-M1 function as a fixed bearing?

The rolling bearing is used in bearing locations where high radial forces occur and, at the same time, axial guidance of the shaft on both sides is required. Due to its fixed bearing design, the assembly absorbs axial forces in both directions. The fixed bearing arrangement prevents axial displacement of the shaft relative to the surrounding housing and thus ensures precise positioning within the drive system.

What functions do the NUP design and the brass cage perform?

The NUP design features two fixed flanges on the outer ring and one fixed flange plus a loose flange disc on the inner ring. This combination holds the rolling elements in place axially and enables force transmission in both directions. The solid brass cage ensures precise spacing of the cylindrical rollers under high dynamic forces. As the outer ring is designed without a groove or lubrication bore and the bearing has no seals, lubricant is supplied via the bearing environment within a temperature range of -30 to +150 degrees Celsius.
