Cylindrical Roller Bearings FAG NJ2213 -E-XL-M1-C3

The FAG NJ2213 -E-XL-M1-C3 cylindrical roller bearing withstands high radial loads and, with dimensions of 65x120x31 mm, provides single-sided axial support.

This single-row cylindrical roller bearing, model NJ2213 -E-XL-M1-C3, is designed to support rotating shafts under heavy radial loads. The manufacturer, FAG, equips this version with a solid brass cage and the increased clearance class C3. As the rolling bearing has an open design, it can be integrated into a customer-supplied lubrication system. Designs subject to impact forces or thermal influences benefit from this combination of material and internal geometry.

In which applications is the NJ2213 -E-XL-M1-C3 cylindrical roller bearing used as a support bearing?

The NJ2213 -E-XL-M1-C3 cylindrical roller bearing is suitable as a support bearing for applications with a predominant radial load and additional unilateral axial forces. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring, which enables the rolling bearing to limit axial displacement in one direction. Typical applications are found in general mechanical engineering for shaft mountings subject to combined loads. The solid brass cage guides the cylindrical rollers stably, even under vibration.

What advantages do the brass cage and C3 clearance offer in this design?

The combination of the M1 brass cage and the C3 radial clearance provides the bearing with thermal and mechanical reserves. A brass cage is characterised by high strength under vibrational loads. The increased operating clearance to C3 compensates for dimensional changes when tight fits are fitted to the shaft and housing, or when temperature differences occur between the inner and outer rings during operation. The permissible temperature range is from -30 to +150 degrees.
