How to read SKF NUP 221 ECP
- NUP 2Series
- Cylindrical roller bearings, NUP 2 series. For the same bore, each series has a different outside diameter and width.
- 21Bore
- 105 mm bore: 21 × 5.
- ECPSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
NUP 221 is the standard (ISO) basic designation: it defines the type, the series and the bore.

SKF NUP series cylindrical roller bearings are components designed to withstand high radial loads and also axial loads in both directions. Their design with a single row of cylindrical rollers and flanges on the inner and outer rings allows robust operation in demanding industrial applications. They are ideal for equipment requiring high load capacity and rigidity, such as machine tools, pumps and gearboxes.
The NUP designation identifies single-row cylindrical roller bearings with flanges on both rings: the inner ring has two fixed flanges and the outer ring has one fixed and one loose flange, which allows them to withstand axial loads in both directions. The ECP suffix indicates an optimized design with a high-strength polyamide cage, which improves roller guidance and reduces friction. The bore diameter varies according to the code; for example, NUP 203 ECP has 17 mm and NUP 210 ECP has 50 mm.
These bearings are used in a wide variety of industries in Argentina, such as metallurgy, cement, mining and food processing. They are common in gearboxes, centrifugal pumps, industrial fans, machine tools and power transmission equipment. Their ability to withstand combined loads and their rigidity make them suitable for applications requiring precision and durability, even under continuous operating conditions.
To correctly select an NUP bearing, take into account the radial and axial load it must withstand, as well as the rotational speed. It is essential to verify the fit and alignment during assembly to avoid additional stresses. Proper lubrication, whether grease or oil, extends service life. Sealing will depend on the environment: in contaminated environments, additional seals are recommended. The polyamide cage of the ECP design offers good resistance to temperature and chemical agents.
Regarding equivalences, SKF NUP bearings can be interchanged with those of other brands that follow the same international designation, such as FAG, NSK or NTN, as long as dimensions and tolerances match. It is important to verify the suffix, as the internal design may vary. At MR Accesorios Industriales we sell SKF, and we can advise you to find the right replacement for your application.

Frequently Asked Questions
- What are the dimensions of the SKF NUP 221 ECP bearing?
- The SKF NUP 221 ECP bearing has a 105 mm bore, a 190 mm outside diameter and a 36 mm width (105 x 190 x 36 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NUP 221.
- What does the ECP suffix mean on an SKF bearing?
- ECP indicates an optimized design with a high-strength polyamide cage, which improves roller guidance and reduces friction. It is common in SKF cylindrical roller bearings.
- Does this bearing support axial loads?
- Yes, the NUP design allows it to withstand axial loads in both directions thanks to the flanges on the inner and outer rings, in addition to high radial loads.
