Decoding SKF NU 322 EM/C4VA301
- NU 3Series
- Cylindrical roller bearings, NU 3 series. Series differ in outside diameter and width even when the bore is the same.
- 22Bore
- Bore 110 mm (22 × 5).
- EM/C4VA301Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 322 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 322 EM/C4VA301 measures 110 mm across the bore and 240 mm across the outside diameter; its width is 50 mm (110 x 240 x 50 mm).

SKF NU series cylindrical roller bearings are built for machinery that carries heavy radial loads at considerable speed. Cylindrical rollers running in a steel cage keep operation precise even in tough duty. Typical homes for these bearings include industrial machinery, gearboxes, electric motors and power transmission equipment. MR Industrial Accessories supplies this line so you can match the right part to your equipment.
Read the code from left to right and the bearing tells you what it does. NU means the outer ring carries two flanges while the inner ring has none, so the shaft can shift axially inside the bearing. The number in the middle gives the dimension series. EM points to a machined brass cage, chosen for high speeds and loads. C4 calls out radial clearance above the standard value, and VA301 is a specific execution tied to tolerances or lubrication. Part numbers in this series combine these features.
You will find these bearings in cement, steel, paper and mining operations, where radial forces run high and conditions are severe. Speed reducers, large centrifugal pumps, industrial fans and machine tools also use them. Plants running continuous production value them because they hold up and are straightforward to maintain. Shafts that need rigid, precise support are a natural fit for this design.
Selection comes down to three inputs: radial load, rotational speed and the internal clearance you need. C4 clearance pays off when thermal effects or tight fits would otherwise close up the running gap. A machined brass EM cage adds strength and helps move heat away. At mounting, check alignment between supports and confirm the fits on shaft and housing. Pick a lubricant that suits the operating temperature and speed, and add seals if the environment carries contamination.
For replacements, keep the dimensions and the specified clearance identical. Bearings from other makers may carry similar designations, yet tolerances and heat treatment can differ. Interchangeability holds when the main dimensions and radial clearance line up. If a part number equivalence is unclear, ask us and we will help sort it out.

Frequently asked questions
- SKF NU 322 EM/C4VA301 bearing: what are its dimensions?
- SKF NU 322 EM/C4VA301 measures 110 mm across the bore and 240 mm across the outside diameter; its width is 50 mm (110 x 240 x 50 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 322.
- What does the C4 suffix mean on an SKF bearing?
- C4 identifies an internal radial clearance larger than the standard value. It suits bearings that run hot or that see interference fits, since those conditions reduce clearance during operation.
- Can an NU bearing take axial loads?
- No. With two flanges on the outer ring and none on the inner ring, an NU bearing carries radial load only. It does allow relative axial displacement between shaft and housing.
- How can I tell whether another brand's bearing is equivalent?
- Compare bore, outer diameter and width, plus the radial clearance and the cage type. Designations differ between makers, but matching those parameters is what makes a bearing interchangeable.
