Decoding SKF NUP 2210 ECP/C3
- NUP 22Series
- Cylindrical roller bearings, NUP 22 series. Series differ in outside diameter and width even when the bore is the same.
- 10Bore
- Bore 50 mm (10 × 5).
- ECP/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NUP 2210 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NUP 2210 ECP/C3 measures 50 mm across the bore and 90 mm across the outside diameter; its width is 23 mm (50 x 90 x 23 mm).

SKF NUP ECP cylindrical roller bearings are single-row units built to handle heavy radial loads on shafts. The range includes designations such as NUP 205 ECP/C3, NUP 2210 ECP/C3 and NUP 316 ECP/C3: they follow the same basic arrangement but belong to different series and sizes, so each one has its own dimensions.
A NUP bearing has an outer ring with two ribs and an inner ring that carries one fixed rib plus a loose rib shaped like a washer. The cylindrical rollers run along the raceways in line contact, which gives the bearing good radial capacity with low friction. Those ribs also let it take a limited axial load in either direction, so the shaft is located axially at that point.
In the part number, NUP identifies the design and ECP forms part of the manufacturer's code. The /C3 marking means internal radial clearance above normal, a common choice when the inner ring is a tight fit or when the assembly warms up during operation; the sample also lists /C4, which is larger still. The middle digits define series and size, so the prefix by itself cannot be used to replace a bearing.
Typical applications include large electric motors, gearboxes, fans and pumps, along with other machines that impose high radial loads. Since it positions the shaft axially, it normally sits at the fixed end of the arrangement, while the opposite end uses a cylindrical roller bearing that permits axial movement from thermal expansion.
During installation, protect the raceways and rollers from impact: the outer ring, rollers and cage come away from the inner ring, and the parts must go back together without force. Verify shaft and housing fits, the resulting operating clearance, and lubrication matched to speed and temperature, as set out in the manufacturer's instructions.
To obtain a quote, contact us on WhatsApp or by email and include the complete part number with the /C3 or /C4 suffix, since internal clearance changes the bearing. If anything is unclear, send a photo of the bearing you are removing. We respond promptly.

Frequently asked questions
- SKF NUP 2210 ECP/C3 bearing: what are its dimensions?
- SKF NUP 2210 ECP/C3 measures 50 mm across the bore and 90 mm across the outside diameter; its width is 23 mm (50 x 90 x 23 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NUP 2210.
- What does C3 mean in these bearings?
- C3 denotes internal radial clearance larger than normal, and C4 denotes one larger than C3. It is written into the part number: a bearing with different clearance is not interchangeable without checking the fit.
- What type of loads does a NUP support?
- It carries high radial loads and, because of its ribs, limited axial loads in both directions. That is why it axially locates the shaft where it is mounted.
- Can I replace it with another one from the same series?
- Only if the full part number matches or if it is confirmed that dimensions, internal clearance and ring type are the same. Send us the part number and we will help you verify it.
