SKF NU MA series cylindrical roller bearings are built for high radial loads and considerable speeds. Their cylindrical rollers and machined brass cage suit demanding industrial machinery. MR Industrial Accessories LLC supplies this line as part of its SKF bearing range.
The NU MA code breaks down as follows: NU means a cylindrical roller bearing with two outer ring ribs and a ribless inner ring, so the shaft can shift axially relative to the housing. The middle digits give the dimension series; for instance, NU 248 MA falls into one diameter and width series, while NU 1060 MA belongs to a larger one. MA indicates a machined brass cage, a common choice for high mechanical and thermal demands.
These bearings appear in steel, cement, mining, paper and machine tool operations. Typical installations include speed reducers, gearboxes, rolling mills, mills, large centrifugal pumps and power transmission equipment. Their rigidity and radial load capacity make them a fit for shafts that need precision and reliability in continuous duty.
When selecting, consider radial load, speed and the operating environment. Mounting calls for accurate alignment between shaft and housing. Because NU bearings permit axial displacement inside the bearing, you do not need to locate both rings axially. Correct lubrication—grease or oil as the application requires—and effective sealing against contaminants help extend service life. Verify internal clearance and shaft and housing tolerances before installation.
SKF NU MA series bearings can be interchanged with other manufacturers' products that use the same standardized designation. Tolerances and internal design can differ between brands, so check the technical specifications and speak with a specialist before substituting. MR Industrial Accessories LLC can advise on interchangeability.

Frequently asked questions
- SKF NU 1064 MA bearing: what are its dimensions?
- SKF NU 1064 MA measures 320 mm across the bore and 480 mm across the outside diameter; its width is 74 mm (320 x 480 x 74 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 1064.
- What does the MA suffix mean in an NU bearing?
- MA indicates a one-piece machined brass cage centered on the outer ring. This cage suits high speeds and temperatures and provides precise roller guidance.
- Does this bearing support axial loads?
- NU bearings are primarily for radial loads. With no ribs on the inner ring, they allow relative axial displacement but do not support significant axial loads. Combined loads require a different design.
- How do I choose between an NU and an NJ bearing?
- NU has two ribs on the outer ring and none on the inner ring, so it only supports radial loads. NJ has one rib on the inner ring and can support axial loads in one direction. The choice depends on whether you need axial location.
