Decoding SKF NU 1060 MA/C3
- NU 10Series
- Cylindrical roller bearings, NU 10 series. Series differ in outside diameter and width even when the bore is the same.
- 60Bore
- Bore 300 mm (60 × 5).
- MA/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 1060 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 1060 MA/C3 measures 300 mm across the bore and 460 mm across the outside diameter; its width is 74 mm (300 x 460 x 74 mm).

Cylindrical roller bearings in the SKF NU range use a machined brass cage, identified by the MA suffix. The NU layout carries two ribs on the outer ring and a rib-free inner ring, so the rings can move axially relative to each other. This makes the series a fit for equipment that combines heavy radial loading with high running speeds. MR Industrial Accessories supplies this line within its bearing catalog for maintenance and purchasing teams across the United States and Latin America.
Reading the code helps when you are matching a replacement. NU tells you the rib arrangement and the resulting axial freedom. MA points to a machined brass cage, a construction chosen for elevated speed and temperature duty. C3 calls out internal radial clearance above the standard value, which suits interference fits and cases where a thermal gradient develops across the bearing. A designation such as NU 248 MA/C3 therefore tells you the series, the cage type and the clearance class before you open a catalog.
Typical installations include gearboxes, large electric motors, centrifugal pumps, industrial fans, machine tools, power transmission equipment and rolling mill rolls. Industries that lean on this series include steel, cement, mining, and pulp and paper, where the bearing has to carry radial load and keep running without constant attention.
Selection starts with the radial load, the rotation speed and the operating environment. Brass cages handle fatigue and speed better than stamped steel types. Choose C3 clearance when the shaft fit is an interference fit or when operating temperature runs high. Shaft and housing alignment matters, and so does lubrication: grease or oil, depending on the application.
For interchange, an SKF NU bearing with brass cage and C3 clearance follows the same standardized designation used by other manufacturers, so equivalents exist. Small differences in dimensions and load capacity can appear between makers, so it pays to check the individual product page before committing. MR Industrial Accessories supplies SKF bearings as part of its catalog.

Frequently asked questions
- SKF NU 1060 MA/C3 bearing: what are its dimensions?
- SKF NU 1060 MA/C3 measures 300 mm across the bore and 460 mm across the outside diameter; its width is 74 mm (300 x 460 x 74 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 1060.
- What does the MA suffix tell me about an NU bearing?
- It identifies a machined brass cage. This cage type resists fatigue well and tolerates higher speeds than a stamped steel cage, which is why it appears in demanding applications.
- When should I specify C3 clearance?
- C3 is an internal radial clearance above the standard value. It is used with interference fits, thermal gradients, or other conditions where extra clearance is needed so the bearing does not run preloaded.
- Can an SKF NU bearing replace one from another maker?
- Yes, when the main dimensions and the standardized designation match. Load capacities and tolerances can differ slightly between manufacturers, so verify before ordering. Send the part number to MR Industrial Accessories for guidance.
