For equipment that has to carry heavy radial loads at speed, the FAG NJ series cylindrical roller bearing is a common choice. Its inner ring has a single rib and the outer ring two, and the solid brass cage adds rigidity and precision. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the United States and Latin America, and can help you match the right variant to your machine.

Reading an NJ part number: the letters NJ mean a cylindrical roller bearing with one fixed rib on the inner ring and two ribs on the outer ring, so the shaft can move axially in one direction. The digits that follow, as in NJ238-E-M1, give the size and dimension series. The -E suffix marks a higher load capacity design, and -M1 identifies the solid brass cage for demanding duty. Other sizes follow the same pattern, for example NJ240-E-M1 or NJ2332-E-M1.

These bearings turn up in gearboxes, centrifugal pumps, compressors, machine tools, conveyors and mining equipment. Their high radial capacity and stiffness suit gear transmissions and setups that need precise rotation. In metallurgical, cement and food plants, they are often found in main spindles and support rollers.

Selecting an NJ bearing starts with radial and axial load, operating speed and the environment. Mounting must align the rings precisely; where thermal expansion occurs, the NJ design permits axial movement in one direction. Grease or oil lubrication is chosen according to temperature and speed. Sealing depends on contamination: in dirty conditions, extra protection is recommended. The solid brass cage contributes strength and heat dissipation.

Cylindrical roller bearings from different makers can vary in suffixes and internal design. Before replacing one, check the main dimensions and load conditions, because not every suffix means the same performance. A specialist can confirm dimensional and functional compatibility. MR Industrial Accessories can provide the technical information for each case.
