Designation explained
What 2201 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 |
|---|---|
22 | Wide self-aligning ball bearing, dimension series 22 (the type digit 1 is omitted by convention) |
01 | 01 → 12 mm bore (fixed code for small bores) |
Variants
Common 2201 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 |
|---|---|---|
K | 2201K | Tapered bore (taper 1:12) for mounting on an adapter or withdrawal sleeve |
2RS | 2201-2RS | Contact seals on both sides (available for selected sizes; may be wider) |
TV / TN9 / M | 2201-TVH | Cage material: polyamide (TV, TN9) or machined brass (M) — letters vary by maker |
CN (no suffix) | 2201 | Normal internal clearance |
C3 | 2201-C3 | Internal clearance greater than normal — common for electric motors and heated shafts |
C4 | 2201-C4 | Internal clearance greater than C3 |

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 2201. 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 2201 bearing?
A 2201 is a self-aligning ball bearing with a 12 mm bore, 32 mm outside diameter and 14 mm width (12 × 32 × 14 mm). These boundary dimensions follow the ISO dimension plan, so they are the same across manufacturers.
Can I replace 2201 with another bearing of the same size?
Other bearing types can share the same 12 × 32 × 14 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.
