6008 (Deep Groove Ball bearing)
The 6008 is a Deep Groove Ball bearing with boundary dimensions of 40 x 68 x 15 mm (bore x outside diameter x width). It has a basic dynamic load rating of 17.8 kN and a basic static load rating of 11.6 kN.
Cross-Reference
| Manufacturer | Reference |
|---|---|
| SKF | 6008 |
| Timken | 6008 |
| FAG (Schaeffler) | 6008 |
Cross-references are matched on the ISO 15 boundary dimensions
(40 x 68 x 15 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
Deep Groove Ball bearings are the most widely used bearing type, carrying radial and moderate axial loads at high speed. The 6008 is commonly found in electric motors, pumps, gearboxes, and general rotating machinery. Dynamic rating 17.8 kN sets the load a bearing can carry for a one-million-revolution rating life (L10), while the static rating 11.6 kN governs the maximum load a stationary bearing can withstand without permanent deformation.
Interchange Notes
When substituting the 6008:
- Match the boundary dimensions (40 x 68 x 15 mm) exactly — this is what guarantees fit.
- Match the bearing type (Deep Groove Ball); mixing roller and ball types changes stiffness, speed limits, and load capacity.
- Match or exceed the dynamic load rating (17.8 kN) for the intended life.
- Respect the seal/shield suffix the application requires (open, Z, 2Z, RS, or 2RS).
