Decoding SKF NU 1052 M/C3
- NU 10Series
- Cylindrical roller bearings, NU 10 series. Series differ in outside diameter and width even when the bore is the same.
- 52Bore
- Bore 260 mm (52 × 5).
- M/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 1052 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 1052 M/C3 measures 260 mm across the bore and 400 mm across the outside diameter; its width is 65 mm (260 x 400 x 65 mm).

SKF NU series cylindrical roller bearings are built to handle substantial radial loads at considerable speeds. Their cylindrical rollers and machined brass cage support precise operation in tough industrial settings. You will find them in rotating equipment that demands high load capacity and rigidity, including gearboxes, electric motors and power transmission systems. MR Industrial Accessories supplies this line as part of its SKF bearing range.
Reading the designation NU … M/C… helps you specify the right bearing. The NU prefix means the outer ring has two ribs while the inner ring has none, so the shaft can move axially relative to the housing. The following number is the size code for the main dimensions. The letter M tells you the cage is machined brass, which handles high speeds and temperatures. The /C3 suffix calls for internal radial clearance above normal, which is useful with interference fits or when the rings see different temperatures. For instance, NU 1020 M/C3 brings these features together in one size.
These bearings appear in metallurgy, cement, mining and food processing. Common equipment includes speed reducers, large centrifugal pumps, industrial fans and machine tools. Their capacity for heavy radial loads and their rigidity suit shafts that need high precision and durability. You will also find them in conveying systems and in the automotive sector, though that industry often uses other rib configurations.
Selecting an NU bearing means checking the radial load, rotational speed and operating environment. Choose C3 clearance when the shaft or housing fit reduces internal clearance, or when running temperatures are high. Lubrication follows speed and temperature: grease for slower applications, oil for high speeds. During mounting, align the rings and avoid impacts that could harm the rollers. The machined brass cage copes better with sudden changes in speed.
For equivalences, SKF NU bearings can be interchanged with other brands that use the same dimensional designation, such as FAG, NSK or NTN, as long as you verify tolerances and radial clearance. The NU series is standard and size codes usually match across manufacturers, but confirming the technical specifications is up to you. MR Industrial Accessories, which supplies SKF, can guide you on specific interchangeability.

Frequently asked questions
- SKF NU 1052 M/C3 bearing: what are its dimensions?
- SKF NU 1052 M/C3 measures 260 mm across the bore and 400 mm across the outside diameter; its width is 65 mm (260 x 400 x 65 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 1052.
- What does the /C3 suffix mean on an NU bearing?
- The /C3 suffix indicates internal radial clearance greater than normal. It is used when interference fits or temperature differences between the inner and outer rings would otherwise reduce clearance during operation, helping to prevent overloads and premature failure.
- Does this bearing allow axial displacement?
- Yes. The NU design has two ribs on the outer ring and none on the inner ring, so the shaft can move axially relative to the housing. This suits applications with thermal expansion or a need for axial freedom.
- Can I replace an NU bearing from another brand with an SKF one?
- Generally yes, provided the dimensions and radial clearance match. The NU series is standard, but check tolerances and the /C3 suffix. Contact us with the original part number and we will advise you on the exact equivalence.
