How to read SKF NUP 212 ECP/C3
- NUP 2Series
- Cylindrical roller bearings, NUP 2 series. For the same bore, each series has a different outside diameter and width.
- 12Bore
- 60 mm bore: 12 × 5.
- ECP/C3Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
NUP 212 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF NUP 212 ECP/C3 bearing has a 60 mm bore, a 110 mm outside diameter and a 22 mm width (60 x 110 x 22 mm).

SKF NUP cylindrical roller bearings with the ECP suffix are single-row roller bearings for shafts that carry high radial loads. This type covers part numbers such as NUP 205 ECP/C3, NUP 2210 ECP/C3 or NUP 316 ECP/C3, which share the same design type but differ in series and size, and therefore each one has its own dimensions.
In a NUP bearing, the outer ring has two ribs and the inner ring has one fixed rib and one loose rib in the form of a washer. The cylindrical rollers contact the raceways with line contact, which provides good radial load capacity and low friction. The ribs also allow limited axial loads to be taken in both directions, so the bearing guides the shaft axially.
In the designation, NUP indicates the design type and ECP is part of the manufacturer's code. The /C3 suffix indicates an internal radial clearance greater than normal, which is common when the inner ring is a tight fit or the assembly heats up in service; the sample also shows /C4, with an even greater clearance. The central numbers identify series and size, so the prefix alone is not enough to replace a bearing.
This type of bearing is used in large electric motors, gearboxes, fans and pumps, among other machines with high radial loads. Because it locates the shaft in the axial direction, it usually occupies the fixed position in the assembly, while a cylindrical roller bearing that allows axial displacement due to thermal expansion is used at the other end.
When installing it, make sure the raceways and rollers are not knocked: the outer ring with the rollers and cage separates from the inner ring, and both parts must be reassembled together without forcing. Check the shaft and housing fits, the resulting operating clearance and lubrication suited to the speed and temperature, following the manufacturer's instructions.
To request a quote, write to us on WhatsApp or by email with the full part number, including the /C3 or /C4 suffix, because the internal clearance changes the bearing. If you have doubts, send us a photo of the one you are removing. We reply promptly, from Buenos Aires, Argentina.

Frequently Asked Questions
- What are the dimensions of the SKF NUP 212 ECP/C3 bearing?
- The SKF NUP 212 ECP/C3 bearing has a 60 mm bore, a 110 mm outside diameter and a 22 mm width (60 x 110 x 22 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NUP 212.
- What does C3 mean in these bearings?
- C3 indicates an internal radial clearance greater than normal, and C4 one even greater than C3. It is part of the part number: a bearing with a different clearance is not interchangeable without reviewing the fit.
- What type of loads does a NUP support?
- It supports high radial loads and, thanks to its ribs, limited axial loads in both directions. That is why it guides the shaft axially at the point where it is installed.
- Can I replace it with another one from the same series?
- Only if the full part number matches or if it is confirmed that the dimensions, internal clearance and ring type are the same. Send us the part number and we will help you verify it.
