The NU series cylindrical roller bearing is a component designed to withstand high radial loads and high speeds. Its design with cylindrical rollers and parallel raceways allows precise operation and high load capacity. It is used in a wide variety of industrial applications, such as gearboxes, electric motors, pumps and transmission equipment. At MR Accesorios Industriales we sell the NSK brand, recognized for its quality and reliability in the industrial market.

The NU series designation is interpreted as follows: the letters NU indicate that the bearing has two ribs on the outer ring and none on the inner ring, which allows relative axial displacement between the shaft and the housing. The numbers that follow indicate the size and the dimension series. For example, NU312 corresponds to a bearing of the medium series with a 60 mm bore, while NU1011 belongs to the light series with a 55 mm bore. Suffixes, such as C3, C4 or ECP, indicate additional characteristics such as increased internal clearance or polyamide cage, respectively.

These bearings are used in numerous industries in Argentina, such as metallurgy, cement, mining, food and petrochemical. They are found in speed reducers, electric motors, centrifugal pumps, industrial fans, machine tools and conveying equipment. Their ability to withstand radial loads makes them ideal for applications where the shaft must rotate at high speeds with precision and reliability.

To correctly select an NU bearing, it is essential to consider the radial load it will have to withstand, the rotation speed, the type of lubrication (grease or oil) and the environmental conditions. Mounting requires precise alignment between the shaft and the housing to avoid additional stresses. It is recommended to use suitable tools, such as pullers and presses, and to check the internal clearance after installation. Lubrication must be adequate to ensure a long service life.

As for equivalences and interchangeability, NSK NU series bearings can be replaced by those of other brands that follow the same designation and standardized dimensions. It is important to verify tolerances and internal clearance to ensure correct operation. If you have any doubts, our technical team can advise you to find the best solution for your application.
