SSNI 518-615 GGG LDZ
Holding a bearing marked SKF SE 518-615 or Timken SNT 518-615? Ours is SSNI 518-615 GGG LDZ — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
SSNI 518-615 GGG LDZ is a bearing, execution: open. For 6 designations (SKF SE 518-615, SKF SN 518-615) interchangeability is conditional — the difference usually lies in radial clearance or cage design, so compare the data sheets before fitting.
Designation equivalents
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.
