22308-E1-XL
Holding a bearing marked SKF 22308C or NSK 22308CDE4 or NTN 22308? Ours is 22308-E1-XL — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
22308-E1-XL is a spherical roller bearing with a 40 × 90 × 33 mm seat, execution: open · clearance CN. The manufacturer's cross-reference catalogue confirms full interchangeability for 16 designations, including SKF 22308C, SKF 22308CC, SKF 22308CC/W33.

Before you replace it
This is a dimensional and design equivalent: the same seat size, the same bearing type and the same sealing and clearance design. It is not the same product — load ratings, tolerance class and grease may differ between manufacturers. For duty close to the limits or a critical application, check the datasheet of the specific design.
The same seat in another execution
These items share the mounting size and have cross-reference tables of their own. They differ in sealing, clearance or cage — exactly what decides how the bearing behaves in the seat.
Where these equivalents come from
The base number of a standard bearing is an ISO standard — 6205 is 6205 at every manufacturer. Only the suffixes describing the design differ, and those are what we translate: shields, contact seals, cage and radial clearance. Designations that mean different things at different makers are deliberately omitted.
