6212-Z-C3
Holding a bearing marked SKF 6212-Z/C3 or NSK 6212ZC3E or NTN 6212ZC3? Ours is 6212-Z-C3 — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
6212-Z-C3 is a deep groove ball bearing with a 60 × 110 × 22 mm seat, execution: single shield · clearance C3. The manufacturer's cross-reference catalogue confirms full interchangeability for 5 designations, including SKF 6212-Z/C3, SKF 6212-ZJEM, NSK 6212ZC3E. Written in the other manufacturers' systems, the same execution also gives NTN 6212ZC3 — 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.
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.
