Cylindrical Roller Bearings FAG NUP2220 -E-XL-M1-C3

The FAG NUP2220 -E-XL-M1-C3 cylindrical roller bearing is a fixed bearing with dimensions of 100 × 180 × 46 mm, designed for high radial loads and axial shaft guidance.

The FAG NUP2220 -E-XL-M1-C3 cylindrical roller bearing is a single-row radial roller bearing in a fixed-end design for shafts with a diameter of 100 mm. Thanks to the NUP geometry, the design accommodates high radial forces as well as axial guidance forces from both directions. The open design without an integrated seal allows for direct lubrication via the customer’s own lubricant supply. With an outer diameter of 180 mm and a width of 46 mm, the bearing unit is suitable for demanding mechanical mounting applications.

What functions does the NUP2220 -E-XL-M1-C3 fulfil within the bearing assembly?

The NUP2220 -E-XL-M1-C3 acts as a fixed bearing within the system and guides rotating shafts in both axial directions via positive engagement. Thanks to the line contact of the cylindrical rollers, the rolling bearing can withstand very high radial forces whilst maintaining high rigidity. The solid brass cage ensures precise guidance of the rolling elements during dynamic accelerations and vibrations. With a temperature range of –30 to +150 degrees, the bearing retains its dimensional stability even under thermal stress.

What does the C3 bearing clearance mean for the NUP2220 -E-XL-M1-C3?

The C3 specification denotes an increased radial clearance compared with the standard version, designed to accommodate thermal and mechanical compensation. This internal clearance compensates for operational temperature differences between the inner and outer rings and prevents the rollers from seizing in tight fits. When installing open bearing assemblies, the housing tolerances and a reliable supply of suitable lubricants must be coordinated.
