30206 (Tapered Roller bearing)
The 30206 is a Tapered Roller bearing with boundary dimensions of 30 x 62 x 17.25 mm (bore x outside diameter x width). It has a basic dynamic load rating of 44 kN and a basic static load rating of 48 kN.
Cross-Reference
| Manufacturer | Reference |
|---|---|
| SKF | 30206 |
| Timken | 30206 |
| FAG (Schaeffler) | 30206 |
Cross-references are matched on the ISO 15 boundary dimensions
(30 x 62 x 17.25 mm) and bearing type, which is what makes parts interchangeable. The
suffixes (e.g. -2RS, -2Z, -E1) encode seals, shields, and internal design
variants, not the envelope size.

Type & Application Notes
Tapered Roller bearings are handles combined radial and axial loads through a tapered raceway, common in wheel and gearbox hubs. The 30206 is commonly found in wheel hubs, automotive differentials, and axle gearboxes. Dynamic rating 44 kN sets the load a bearing can carry for a one-million-revolution rating life (L10), while the static rating 48 kN governs the maximum load a stationary bearing can withstand without permanent deformation.
Interchange Notes
When substituting the 30206:
- Match the boundary dimensions (30 x 62 x 17.25 mm) exactly — this is what guarantees fit.
- Match the bearing type (Tapered Roller); mixing roller and ball types changes stiffness, speed limits, and load capacity.
- Match or exceed the dynamic load rating (44 kN) for the intended life.
- Respect the seal/shield suffix the application requires (open, Z, 2Z, RS, or 2RS).
