SKF NU series cylindrical roller bearings are components designed to withstand high radial loads and considerable speeds. Their design with cylindrical rollers and steel cage allows precise operation in demanding applications. They are used in industrial machinery, gearboxes, electric motors and power transmission equipment. At MR Accesorios Industriales we sell this line so you can find the right part for your equipment.
The NU … EM/C…VA… designation is interpreted as follows: NU indicates that the outer ring has two flanges and the inner ring none, which allows relative axial displacement. The central number defines the dimension series. The EM suffix indicates a machined brass cage, suitable for high speeds and loads. C4 sets a radial clearance greater than standard, and VA301 corresponds to a particular execution specification, generally linked to tolerances or lubrication. The part numbers in this series show this combination of features.
These bearings are used in industries such as cement, steel, paper and mining, where radial loads are intense and working conditions are demanding. They are also found in speed reducers, large centrifugal pumps, industrial fans and machine tools. In Argentina, they are common in continuous production plants, where reliability and ease of maintenance are key. Their ability to withstand radial loads makes them ideal for shafts with supports that require rigidity and precision.
To select the right bearing, take into account the radial load, the rotational speed and the required internal clearance. The C4 suffix indicates a greater clearance, useful when there are thermal interferences or tight fits. The EM machined brass cage offers strength and heat dissipation. During mounting, ensure correct alignment between the supports and verify the fit on the shaft and in the housing. Lubrication must be suitable for the operating temperature and speed. If the bearing works in contaminated environments, consider additional seals.
When looking for replacements, it is essential to respect the dimensions and the specified clearance. Other manufacturers may offer bearings with equivalent designations, but tolerances and treatment may vary. Interchangeability between brands exists if the main dimensions and radial clearance are maintained. Consult us if you have questions about the equivalence of a part number.

Frequently Asked Questions
- What are the dimensions of the SKF NU 322 EM/C4VA301 bearing?
- The SKF NU 322 EM/C4VA301 bearing has a 110 mm bore, a 240 mm outside diameter and a 50 mm width (110 x 240 x 50 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 322.
- What does the C4 suffix mean on an SKF bearing?
- The C4 suffix indicates an internal radial clearance greater than standard. It is used when the bearing operates at high temperatures or with interference fits that reduce clearance during operation.
- Does this bearing support axial loads?
- NU bearings have an outer ring with two flanges and an inner ring without flanges, so they cannot support axial loads. They are used exclusively for radial loads, although they allow relative axial displacement.
- How do I know if a bearing from another brand is equivalent?
- You must compare the main dimensions (bore, outer diameter and width), the radial clearance and the cage type. The designation may vary between manufacturers, but if those parameters match, it may be interchangeable.
