1301-TVH
Holding a bearing marked SKF 1301ETN9 or KOYO 1301 or STEYR 1301E/TG? Ours is 1301-TVH — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
1301-TVH is a Self-aligning ball bearing with a 12 × 37 × 12 mm seat, execution: open · clearance CN. The manufacturer's cross-reference catalogue confirms full interchangeability for 2 designations, including SKF 1301ETN9, STEYR 1301E/TG. For 5 designations (SKF 1301, KOYO 1301) interchangeability is conditional — the difference usually lies in radial clearance or cage design, so compare the data sheets before fitting.

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.
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.
