Designation explained
What NU2212 means
Standard bearing numbers encode the type, the dimension series and the bore. Anything after the base number — seals, clearance, cage — is a suffix.
| Part | Meaning |
|---|---|
NU | Cylindrical roller bearing, two flanges on the outer ring, none on the inner ring (NJ, NUP and N are other flange arrangements) |
22 | Dimension series 22 |
12 | 12 → 60 mm bore (12 × 5) |
Variants
Common NU2212 variants
Suffixes change the bearing without changing its boundary dimensions. The exact letters differ between manufacturers — always order by the full designation from the maker you choose.
| Suffix | Example | Meaning |
|---|---|---|
NJ / NUP / N | NJ2212 | Other flange arrangements with the same d × D × B — they locate the shaft differently and are not interchangeable without checking |
E / EC | NU2212E | Reinforced internal design with more or larger rollers (higher load rating) |
M / P / J | NU2212-E-M1 | Cage: brass (M), polyamide (P / TVP) or pressed steel (J) |
CN (no suffix) | NU2212 | Normal internal clearance |
C3 | NU2212-C3 | Internal clearance greater than normal — common for electric motors and heated shafts |
C4 | NU2212-C4 | Internal clearance greater than C3 |
Same envelope
Same 60 × 110 × 28 mm, different type
These bearings have exactly the same bore, outside diameter and width but are a different type. They fit the same housing and shaft, but carry loads differently — same size is not the same function.
Same bore
Other 60 mm bore bearings
Every standard bearing in this reference with a 60 mm bore, from light to heavy sections.

About these dimensions. Boundary dimensions follow ISO 15 (radial bearings — boundary dimensions, general plan), dimension series 22, and are the same for every manufacturer of a standard NU2212. Chamfers, load ratings, speed limits and weight depend on the manufacturer and design and are not shown — use the maker's datasheet for engineering decisions. Last checked 9 October 2026.

What size is a NU2212 bearing?
A NU2212 is a cylindrical roller bearing with a 60 mm bore, 110 mm outside diameter and 28 mm width (60 × 110 × 28 mm). These boundary dimensions follow the ISO dimension plan, so they are the same across manufacturers.
Is NJ2212 the same as NU2212?
NJ2212, NUP2212 have the same bore, outside diameter and width as NU2212, but different ring flanges. They guide the shaft axially in different ways, so swapping them changes how the arrangement works.
Can I replace NU2212 with another bearing of the same size?
Other bearing types can share the same 60 × 110 × 28 mm envelope, but a different type has different load directions, speed limits and mounting needs. Same dimensions alone do not make two bearings interchangeable.
Where are the load ratings and speed limits?
They depend on the manufacturer and internal design, so we do not list a single value. Check the datasheet for the exact full designation you intend to use.
