NU2332 bearing
160 × 340 × 114 mm
The NU2332 is a cylindrical roller bearing with a 160 mm bore, 340 mm outside diameter and 114 mm width. NJ2332, NUP2332 share these boundary dimensions with a different flange arrangement. Wide medium series; NJ23 and NUP23 share these dimensions.

Designation explained
What NU2332 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) |
23 | Dimension series 23 |
32 | 32 → 160 mm bore (32 × 5) |
Variants
Common NU2332 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 | NJ2332 | Other flange arrangements with the same d × D × B — they locate the shaft differently and are not interchangeable without checking |
E / EC | NU2332E | Reinforced internal design with more or larger rollers (higher load rating) |
M / P / J | NU2332-E-M1 | Cage: brass (M), polyamide (P / TVP) or pressed steel (J) |
CN (no suffix) | NU2332 | Normal internal clearance |
C3 | NU2332-C3 | Internal clearance greater than normal — common for electric motors and heated shafts |
C4 | NU2332-C4 | Internal clearance greater than C3 |
Same envelope
Same 160 × 340 × 114 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.
| Designation | Type | Dimensions |
|---|---|---|
| 22332 | Spherical roller bearing | 160 × 340 × 114 mm |
Same bore
Other 160 mm bore bearings
Every standard bearing in this reference with a 160 mm bore, from light to heavy sections.

| 6232 | Deep groove ball bearing | 290 mm | 48 mm |

About these dimensions. Boundary dimensions follow ISO 15 (radial bearings — boundary dimensions, general plan), dimension series 23, and are the same for every manufacturer of a standard NU2332. 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 NU2332 bearing?
A NU2332 is a cylindrical roller bearing with a 160 mm bore, 340 mm outside diameter and 114 mm width (160 × 340 × 114 mm). These boundary dimensions follow the ISO dimension plan, so they are the same across manufacturers.
Is NJ2332 the same as NU2332?
NJ2332, NUP2332 have the same bore, outside diameter and width as NU2332, but different ring flanges. They guide the shaft axially in different ways, so swapping them changes how the arrangement works.
Can I replace NU2332 with another bearing of the same size?
Other bearing types can share the same 160 × 340 × 114 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.
