Designation explained
What 32012X 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 |
|---|---|
3 | Tapered roller bearing |
20 | Dimension series 20 (ISO 355) |
12 | 12 → 60 mm bore (12 × 5) |
X | Design conforming to the ISO dimension plan for this series |
Variants
Common 32012X 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 |
|---|---|---|
J2 / Q (SKF) | 32012X-J2/Q | Pressed steel cage / optimised contact geometry |
A / U / D | 32012X-A | Internal design variants from different makers (e.g. FAG A, NTN U, NTN D steep angle) |
Cone / cup | 32012X cone | Tapered bearings are separable; cone (inner) and cup (outer) can be sold separately |
DF / DB / pair | 32012X-DF | Matched pairs for preloaded arrangements |

About these dimensions. Boundary dimensions follow ISO 355 (metric tapered roller bearings — boundary dimensions), dimension series 20, and are the same for every manufacturer of a standard 32012X. 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 32012X bearing?
A 32012X is a tapered roller bearing with a 60 mm bore, 95 mm outside diameter and 23 mm total width (T) (60 × 95 × 23 mm). These boundary dimensions follow the ISO dimension plan, so they are the same across manufacturers.
What are the cone and cup widths of a 32012X?
The cone (inner ring) is 23 mm wide and the cup (outer ring) 17.5 mm; assembled, the bearing measures 23 mm (T). Cones and cups of the same designation are interchangeable between manufacturers that follow ISO 355.
Can I replace 32012X with another bearing of the same size?
Other bearing types can share the same 60 × 95 × 23 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.
