How to read SKF NUP 215 ECM/C3
- NUP 2Series
- Cylindrical roller bearings, NUP 2 series. For the same bore, each series has a different outside diameter and width.
- 15Bore
- 75 mm bore: 15 × 5.
- ECM/C3Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
NUP 215 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF NUP 215 ECM/C3 bearing has a 75 mm bore, a 130 mm outside diameter and a 25 mm width (75 x 130 x 25 mm).

SKF NUP series cylindrical roller bearings are high radial capacity components, designed to withstand high radial loads and considerable speeds. Their design includes an inner ring with two ribs and an outer ring with one rib, allowing axial location in both directions. They are ideal for applications requiring high rigidity and precision, such as machine tools, gearboxes and industrial equipment. At MR Accesorios Industriales we carry them as part of our SKF bearing offering.
The NUP series designation is complemented by suffixes that indicate specific features. For example, NUP 215 ECM/C3 combines size 215 with a machined brass cage design (ECM) and a C3 internal radial clearance, which is greater than standard. NUP 218 ECM/C4 has a C4 clearance, even wider, for applications with high temperatures or fits that reduce clearance. NUP 224 ECM/C3 and NUP 308 ECM/C3 follow the same logic: the number indicates the size, while ECM and the C3 or C4 suffix define the execution. Knowing these codes makes selection easier.
These bearings are used in a wide variety of industries in Argentina, such as metallurgy, cement, mining, food and machine tools. They are common in gearboxes, milling machine spindles, industrial pumps, fans and power transmission equipment. Their ability to withstand heavy radial loads and their rigidity make them suitable for applications requiring precision and durability, even under demanding operating conditions.
To correctly select an NUP bearing, it is essential to consider the radial and axial load, the rotation speed and the environmental conditions. Mounting must be carried out with suitable tools, avoiding blows that could damage the rollers or raceways. Lubrication, whether grease or oil, must be appropriate for the temperature and speed. Alignment between shaft and housing is critical to avoid additional loads. The C3 and C4 suffixes indicate greater internal clearances, useful when thermal expansion or interference fits are expected.
As for equivalents and interchangeability, SKF NUP series bearings can be replaced by products from other brands that follow the same dimensional and execution designation, such as FAG, NSK or NTN, as long as tolerances and clearance are verified. It is important to consult the technical specifications of each manufacturer to ensure compatibility. At MR Accesorios Industriales we carry SKF as a brand, and we can advise you on the best option for your application.

Frequently Asked Questions
- What are the dimensions of the SKF NUP 215 ECM/C3 bearing?
- The SKF NUP 215 ECM/C3 bearing has a 75 mm bore, a 130 mm outside diameter and a 25 mm width (75 x 130 x 25 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NUP 215.
- What does the C3 suffix mean on an NUP bearing?
- The C3 suffix indicates an internal radial clearance greater than standard. This is useful in applications where high operating temperatures or interference fits reduce clearance during operation, thus avoiding excessive preload.
- What is the difference between the ECM and EC suffixes?
- ECM refers to a one-piece machined brass cage, while EC indicates a stamped steel cage. The brass cage offers greater strength and is used in more demanding applications, although both designs are valid depending on the application.
- Can I replace an SKF NUP bearing with another brand?
- Yes, as long as the dimensional designation and internal clearance match. Brands such as FAG, NSK or NTN offer equivalents. It is advisable to verify tolerances and specific features to ensure correct operation in your equipment.
