Designation explained
What 7236 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 |
|---|---|
7 | Single-row angular contact ball bearing |
2 | Diameter series 2, dimension series 02 |
36 | 36 → 180 mm bore (36 × 5) |
Variants
Common 7236 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 |
|---|---|---|
B / BE | 7236B | 40° contact angle |
AC | 7236AC | 25° contact angle |
C | 7236C | 15° contact angle (mostly precision bearings) |
DB / DF / DT | 7236B-DB | Matched pair arranged back-to-back / face-to-face / tandem |
M / TVP / J | 7236B-M | Cage: brass (M), polyamide (TVP) or pressed steel (J) |
Same envelope
Same 180 × 320 × 52 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

About these dimensions. Boundary dimensions follow ISO 15 (radial bearings — boundary dimensions, general plan), dimension series 02, and are the same for every manufacturer of a standard 7236. 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 7236 bearing?
A 7236 is a angular contact ball bearing with a 180 mm bore, 320 mm outside diameter and 52 mm width (180 × 320 × 52 mm). These boundary dimensions follow the ISO dimension plan, so they are the same across manufacturers.
Can I replace 7236 with another bearing of the same size?
Other bearing types can share the same 180 × 320 × 52 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.
