61810
Holding a bearing marked SKF 61810 or NSK 61810 or NTN 61810? Ours is 61810 — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
61810 is a deep groove ball bearing with a 50 × 65 × 7 mm seat, execution: open · clearance CN. The designation suffixes indicate SKF 61810, NSK 61810, NTN 61810 as its counterparts.

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.
