2307-M
Holding a bearing marked SKF 2307EM or RHP 2307M or STEYR 2307E/M? Ours is 2307-M — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
2307-M is a Self-aligning ball bearing with a 35 × 80 × 31 mm seat, execution: open · clearance CN. The manufacturer's cross-reference catalogue confirms full interchangeability for 4 designations, including SKF 2307EM, SKF 2307M, RHP 2307M.

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.
