How to read SKF NU 1034 M/C3
- NU 10Series
- Cylindrical roller bearings, NU 10 series. For the same bore, each series has a different outside diameter and width.
- 34Bore
- 170 mm bore: 34 × 5.
- M/C3Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
NU 1034 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF NU series cylindrical roller bearings are components designed to withstand high radial loads and considerable speeds. Their design with cylindrical rollers and machined brass cage enables precise operation in demanding industrial applications. They are used in rotating machinery where high load capacity and rigidity are required, such as gearboxes, electric motors and power transmission equipment. MR Accesorios Industriales sells this line as part of its SKF bearing offering.
The designation NU … M/C… is interpreted as follows: the prefix NU indicates that the bearing has two ribs on the outer ring and none on the inner ring, which allows relative axial displacement. The number that follows is the size code that defines the main dimensions. The letter M indicates that the cage is machined brass, suitable for high speeds and temperatures. The suffix /C3 specifies an internal radial clearance greater than normal, useful when there are interference fits or thermal differences between rings. For example, NU 1020 M/C3 combines these characteristics in a specific size.
These bearings are used in industries such as metallurgy, cement, mining and food processing. In Argentina, they are common in speed reducers, large centrifugal pumps, industrial fans and machine tools. Their ability to withstand heavy radial loads and their rigidity make them suitable for shafts where high precision and durability are required. They are also found in conveying equipment and in the automotive industry, although in the latter, variants with other rib configurations are usually used.
To correctly select an NU bearing, it is essential to consider the radial load, rotational speed and environmental conditions. The C3 clearance is recommended when the fit on the shaft or in the housing reduces internal clearance, or when the operating temperature is high. Lubrication must be chosen according to speed and temperature: grease for slow applications or oil for high speeds. During mounting, it is crucial to align the rings and avoid impacts that could damage the rollers. The machined brass cage better tolerates sudden accelerations and decelerations.
Regarding equivalences, SKF NU bearings can be interchanged with those of other brands that follow the same dimensional designation, such as FAG, NSK or NTN, provided that tolerances and radial clearance are verified. The NU series is standard and size codes usually match between manufacturers, but it is the user's responsibility to confirm the technical specifications. MR Accesorios Industriales, which sells SKF, can advise you on the specific interchangeability.

Frequently Asked Questions
- What are the dimensions of the SKF NU 1034 M/C3 bearing?
- The SKF NU 1034 M/C3 bearing has a 170 mm bore, a 260 mm outside diameter and a 42 mm width (170 x 260 x 42 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 1034.
- What does the /C3 suffix mean on an NU bearing?
- The /C3 suffix indicates an internal radial clearance greater than normal. It is used when the interference fit or thermal differences between inner and outer rings reduce clearance during operation, thus preventing overloads and premature failures.
- Does this bearing allow axial displacement?
- Yes, the NU design has two ribs on the outer ring and none on the inner ring, which allows the shaft to move axially relative to the housing. This is useful in applications where there is thermal expansion or a need for axial freedom.
- Can I replace an NU bearing from another brand with an SKF one?
- In general, yes, as long as the dimensions and radial clearance match. The NU series is standard, but check the tolerances and the /C3 suffix. Consult us with the original part number and we will advise you on the exact equivalence.
