22310 E (Spherical Roller bearing)
The 22310 E is a Spherical Roller bearing with boundary dimensions of 50 x 110 x 40 mm (bore x outside diameter x width). It has a basic dynamic load rating of 220 kN and a basic static load rating of 240 kN.
Cross-Reference
| Manufacturer | Reference |
|---|---|
| SKF | 22310 E |
| Timken | 22310 |
| FAG (Schaeffler) | 22310-E1 |
Cross-references are matched on the ISO 15 boundary dimensions
(50 x 110 x 40 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
Spherical Roller bearings are very high radial capacity with self-alignment for heavy, misaligned industrial duty. The 22310 E is commonly found in crushers, vibrating screens, paper machines, and heavy gearboxes. Dynamic rating 220 kN sets the load a bearing can carry for a one-million-revolution rating life (L10), while the static rating 240 kN governs the maximum load a stationary bearing can withstand without permanent deformation.
Interchange Notes
When substituting the 22310 E:
- Match the boundary dimensions (50 x 110 x 40 mm) exactly — this is what guarantees fit.
- Match the bearing type (Spherical Roller); mixing roller and ball types changes stiffness, speed limits, and load capacity.
- Match or exceed the dynamic load rating (220 kN) for the intended life.
- Respect the seal/shield suffix the application requires (open, Z, 2Z, RS, or 2RS).
