6006-RSR-C3
Holding a bearing marked SKF 6006-RSJEM or NSK 6006DUC3 or NTN 6006LUC3? Ours is 6006-RSR-C3 — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
6006-RSR-C3 is a deep groove ball bearing with a 30 × 55 × 13 mm seat, execution: single seal · clearance C3. For 1 designation (SKF 6006-RSJEM) interchangeability is conditional — the difference usually lies in radial clearance or cage design, so compare the data sheets before fitting. Written in the other manufacturers' systems, the same execution also gives NSK 6006DUC3, NTN 6006LUC3 — 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.
