Designation explained
What 32220 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 |
22 | Dimension series 22 (ISO 355) |
20 | 20 → 100 mm bore (20 × 5) |
Variants
Common 32220 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) | 32220-J2/Q | Pressed steel cage / optimised contact geometry |
A / U / D | 32220-A | Internal design variants from different makers (e.g. FAG A, NTN U, NTN D steep angle) |
Cone / cup | 32220 cone | Tapered bearings are separable; cone (inner) and cup (outer) can be sold separately |
DF / DB / pair | 32220-DF | Matched pairs for preloaded arrangements |

About these dimensions. Boundary dimensions follow ISO 355 (metric tapered roller bearings — boundary dimensions), dimension series 22, and are the same for every manufacturer of a standard 32220. 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 32220 bearing?
A 32220 is a tapered roller bearing with a 100 mm bore, 180 mm outside diameter and 49 mm total width (T) (100 × 180 × 49 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 32220?
The cone (inner ring) is 46 mm wide and the cup (outer ring) 39 mm; assembled, the bearing measures 49 mm (T). Cones and cups of the same designation are interchangeable between manufacturers that follow ISO 355.
Can I replace 32220 with another bearing of the same size?
Other bearing types can share the same 100 × 180 × 49 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.
