How to read SKF NU 1052 MA
- NU 10Series
- Cylindrical roller bearings, NU 10 series. For the same bore, each series has a different outside diameter and width.
- 52Bore
- 260 mm bore: 52 × 5.
- MASuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
NU 1052 is the standard (ISO) basic designation: it defines the type, the series and the bore.

SKF NU MA series cylindrical roller bearings are components designed to withstand high radial loads and considerable speeds. Their design with cylindrical rollers and machined brass cage makes them suitable for demanding applications in industrial machinery. At MR Accesorios Industriales we sell this line as part of our SKF bearing offering.
The NU … MA designation is interpreted as follows: the prefix NU indicates a cylindrical roller bearing with two ribs on the outer ring and none on the inner ring, which allows relative axial displacement. The central number identifies the dimension series; for example, in NU 248 MA the 248 corresponds to a specific diameter and width series, while in NU 1060 MA the 1060 indicates a larger size series. The suffix MA designates a machined brass cage, for general use in applications with high mechanical and thermal demands.
These bearings are used in industries such as steel, cement, mining, paper and machine tools. In Argentina, they are common in speed reducers, gearboxes, rolling mills, mills, large centrifugal pumps and power transmission equipment. Their ability to withstand high radial loads and their rigidity make them suitable for shafts that require high precision and reliability in continuous service.
To select correctly, take into account the radial load, rotation speed and environmental conditions. Mounting must ensure precise alignment between shaft and housing; NU bearings allow axial displacement within the bearing itself, so you do not need to fix both rings axially. Proper lubrication —grease or oil depending on the application— and effective sealing against contaminants extend service life. Check the internal clearance and the shaft and housing tolerances before installing.
As for equivalents, SKF NU MA series cylindrical roller bearings can be interchanged with products from other manufacturers that follow the same standardized designation. However, tolerances and internal design may vary between brands, so it is advisable to verify the technical specifications and consult a specialist before replacing. At MR Accesorios Industriales we can advise you on interchangeability.

Frequently Asked Questions
- What are the dimensions of the SKF NU 1052 MA bearing?
- The SKF NU 1052 MA bearing has a 260 mm bore, a 400 mm outside diameter and a 65 mm width (260 x 400 x 65 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 1052.
- What does the MA suffix mean in an NU bearing?
- The MA suffix indicates that the bearing has a one-piece machined brass cage, centered on the outer ring. This cage is suitable for high speeds and temperatures, and provides precise roller guidance.
- Does this bearing support axial loads?
- NU bearings are designed primarily for radial loads. Since they have no ribs on the inner ring, they allow relative axial displacement, but they do not support significant axial loads. For combined loads, a different design is required.
- How do I choose between an NU and an NJ bearing?
- The NU has two ribs on the outer ring and none on the inner ring, so it only supports radial loads. The 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.
