Designation explained
What 22238 means
Standard bearing numbers encode the type, the dimension series and the bore. Anything after the base number — seals, clearance, cage — is a suffix.

Variants
Common 22238 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 |
|---|---|---|
E / CC / CA | 22238E | Internal design generation and cage type; letters differ between manufacturers |
K | 22238K | Tapered bore (1:12) for adapter or withdrawal sleeve mounting |
W33 | 22238-W33 | Annular groove and lubrication holes in the outer ring |
CN (no suffix) | 22238 | Normal internal clearance |
C3 | 22238-C3 | Internal clearance greater than normal — common for electric motors and heated shafts |
C4 | 22238-C4 | Internal clearance greater than C3 |
Same envelope
Same 190 × 340 × 92 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 |
|---|---|---|
| NU2238 | Cylindrical roller bearing | 190 × 340 × 92 mm |
Same bore

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 22238. 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 22238 bearing?
A 22238 is a spherical roller bearing with a 190 mm bore, 340 mm outside diameter and 92 mm width (190 × 340 × 92 mm). These boundary dimensions follow the ISO dimension plan, so they are the same across manufacturers.
Can I replace 22238 with another bearing of the same size?
Other bearing types can share the same 190 × 340 × 92 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.
