SKF NU series cylindrical roller bearings are components designed to withstand high radial loads and considerable speeds. Their design with cylindrical rollers and machined brass cage allows precise operation in demanding industrial applications. They are used in heavy machinery, gearboxes, pumps and power transmission equipment. At MR Accesorios Industriales we carry this line backed by more than 80 years in the Argentine market.

The designation NU … ECML/C…B… is interpreted as follows: NU indicates that the outer ring has two ribs and the inner ring none, which allows relative axial displacement. The central number (for example, 218, 219, 221, 222, 321, 322) defines the size and dimension series. The suffix EC indicates high-capacity rollers, ML a machined brass cage guided by the rollers, C3 increased internal radial clearance and B20 a specific design modification. These codes are key to selecting the correct bearing.

These bearings are used in industries such as steel, cement, mining, paper and machinery manufacturing. In Argentina, they are common in speed reducers, gearboxes, centrifugal pumps, industrial fans and transmission equipment. Their ability to withstand high radial loads and their rigidity make them suitable for shafts where high precision and durability are required. They are also found in railway applications and in the automotive industry.

To select the right bearing, take into account the radial load, the rotational speed and the environmental conditions. The suffix C3 indicates a greater internal clearance than normal, useful when there are thermal gradients between rings. The ML machined brass cage is resistant and suitable for high speeds. During mounting, ensure precise alignment of the shaft and the housing, and adequate lubrication (grease or oil) according to the application. Check the fit and cleanliness to avoid premature failures.

SKF NU series bearings can be interchanged with equivalent products from other brands that follow the same international designation. When looking for a replacement, check the main dimensions (bore, outside diameter and width) and the tolerances. Interchangeability is not always direct; consider the internal clearance, the cage and the operating conditions. At MR Accesorios Industriales we can advise you on the right equivalent for your equipment, without compromising performance.
