The FAG NJ series is a cylindrical roller bearing built for radial capacity, with rollers running between an inner and an outer ring. Certain variants also take axial load in a single direction. You will find this design in gearboxes, pumps, industrial fans and machine tools, where rigidity and running accuracy matter. MR Industrial Accessories LLC supplies this line.

Reading an NJ part number is a matter of breaking it into blocks. The letters NJ describe a cylindrical roller bearing that carries a rib on the inner ring and none on the outer ring, so the shaft can shift axially relative to the housing. The digits that follow, as in NJ228, NJ230 or NJ232, set the size and the dimension series. The -E suffix marks a version built for higher load capacity, -XL the long-life execution, and -M1 the machined brass cage. A full designation such as NJ228-E-XL-M1 therefore stacks all of these traits into one number.

Typical service points include reducers and gearboxes, centrifugal pumps, induced draft fans, pulp and paper lines, and mining or cement machinery. Machine tool spindles and rolling mill rolls are other common homes for these bearings. High radial capacity together with a stiff, precise running behavior suits shafts that turn at medium to high speeds and are expected to hold accuracy over a long service life.

Choosing the right unit starts with the radial load, the axial load, the speed and the lubrication method. NJ bearings accept axial load in one direction only, so applications needing guidance both ways call for a second bearing or a different variant. Fitting demands careful alignment and a clean seat. Grease or oil both work, depending on how hot the bearing runs. How you seal it depends on the surroundings, and dusty or damp locations usually call for extra protection.

Bearings from other makers can often be swapped in when the dimensions, tolerances and load capacity line up. FAG designations frequently have counterparts elsewhere, though the letters and digits rarely match exactly. Check the complete part number and the operating conditions before you substitute anything. Our team can point you to a suitable equivalent for your equipment.
