Cylindrical Roller Bearings FAG NJ2224 -E-M1

The FAG NJ2224 -E-M1 cylindrical roller bearing offers high radial load-carrying capacity with dimensions of 120 × 215 × 58 mm and functions as a support bearing with single-sided axial guidance.

The FAG NJ2224 -E-M1 cylindrical roller bearing is a single-row radial roller bearing that withstands high radial loads whilst maintaining a compact design. As a support bearing, the inner ring guides the shaft in the axial direction, whilst the opposite side compensates for axial displacement. With a bore of 120 mm, an outer diameter of 215 mm and a width of 58 mm, this open roller bearing is suitable for bearing arrangements subject to high radial forces and requiring axial length compensation.

What are the functions of the NJ design of the NJ2224 -E-M1 cylindrical roller bearing?

This single-row roller bearing is used when high radial loads act on the bearing location and, at the same time, axial forces must be accommodated in one direction. The NJ design features two fixed flanges on the outer ring and one fixed flange on the removable inner ring. As a result, the bearing provides axial support to the shaft on one side, whilst axial displacement in the opposite direction remains possible. As an open bearing, lubrication with oil or grease is provided via the surrounding housing.

What are the distinctive features of the M1 brass cage in the NJ2224 -E-M1 cylindrical roller bearing?

The solid brass cage (designation M1) guides the cylindrical rollers and provides mechanical strength against vibrations or shock loads. In conjunction with standard radial clearance, this design complies with tolerance class P0 (ABEC 1). The specified operating temperature range is from -30 to +150 degrees. As the inner ring is removable from one side, the inner and outer rings can be fitted separately.
