Cylindrical Roller Bearings FAG NUP322 -E-XL-M1-C3

The FAG NUP322 -E-XL-M1-C3 cylindrical roller bearing, measuring 110 × 240 × 50 mm, serves as a robust fixed bearing for high radial loads.

This single-row cylindrical roller bearing, the NUP322 -E-XL-M1-C3 from FAG, can withstand very high radial forces thanks to its cylindrical rollers. As an open design without a seal, the bearing is intended for operation with external lubrication. The NUP design is characterised by two fixed flanges on the outer ring, one fixed flange on the inner ring and a loose flange disc. As a result, the rolling bearing guides the shaft axially in both directions.

What is the NUP322 -E-XL-M1-C3 cylindrical roller bearing suitable for as a fixed bearing?

Design engineers primarily use this design where high radial forces are combined with axial fixation on both sides. The bearing guides shafts accurately in the axial direction and absorbs short-term axial forces. Typical applications include industrial gearboxes and drive systems. Thanks to its wide temperature range of –30 to +150 degrees, the bearing operates smoothly even under demanding thermal operating conditions.

What are the advantages of a brass cage and C3 clearance?

This design features a solid brass cage that guides the rollers even during high acceleration or vibration. The increased C3 bearing clearance group offers more radial play compared to standard clearance. This helps to prevent the rolling elements from becoming jammed when operational heating or tight fits cause the inner ring to expand. To function correctly, the open bearing requires a clean installation environment and a suitable lubrication system.
