61807
Holding a bearing marked SKF 61807 or NSK 61807 or NTN 61807? Ours is 61807 — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
61807 is a deep groove ball bearing with a 35 × 47 × 7 mm seat, execution: open · clearance CN. The manufacturer's cross-reference catalogue confirms full interchangeability for 2 designations, including SKF 61807, ZWZ 61807. Written in the other manufacturers' systems, the same execution also gives NSK 61807, NTN 61807 — our reading of the designation suffixes, not a catalogue entry.

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.
