The FAG NJ series cylindrical roller bearing is a component with high radial load capacity, designed to withstand heavy loads and considerable speeds. Its brass cage construction and special dimensional treatment make it suitable for demanding applications in industrial machinery. MR Accesorios Industriales sells this line for the Argentine market, with technical advice to select the correct variant for each piece of equipment.
The designation of these bearings is interpreted as follows: the letters NJ indicate that the inner ring has one rib and the outer ring has two, allowing axial guidance in one direction. The number following the letters (for example, 2334, 2336, 2338 or 2340) defines the size and load capacity. The suffix EX indicates a design with higher capacity and optimized dimensions; TB identifies the machined brass cage, and M1 indicates heat treatment stabilized for high temperatures. Knowing these codes makes it easier to order the exact replacement.
These bearings are used in applications where radial loads are intense and rigidity is required, such as gearboxes, machine tools, industrial pumps, large fans and mining equipment. In Argentina, they are common in the oilseed, steel, cement and mineral processing industries. Their ability to withstand combined loads and their fatigue resistance make them suitable for continuous operation and severe conditions.
To select the correct bearing, take into account radial and axial load, rotation speed and environmental conditions. Sealing or protection against contaminants is key: if the equipment operates in dusty environments, a variant with seals is recommended. Lubrication must be suitable for the temperature and speed; generally, high-viscosity greases or oils are used. Installation requires precise alignment and correct adjustment of internal clearance to avoid premature failure.
FAG NJ series bearings are interchangeable with those of other brands that follow the same dimensional and design nomenclature. When requesting a quote, it is important to verify tolerances and internal clearance, as they can vary between manufacturers. MR Accesorios Industriales can advise you on equivalences and options that apply to your specific application.
