GRA103-NPP-B-AS2/V
Holding a bearing marked AMI KH206-19 or FAFNIR GRA103NPPB or TR GRA206-19? Ours is GRA103-NPP-B-AS2/V — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
GRA103-NPP-B-AS2/V is a Radial insert ball bearing with a 30.1625 × 62 × 23.8 mm seat, execution: open. The manufacturer's cross-reference catalogue confirms full interchangeability for 4 designations, including AMI KH206-19, FAFNIR GRA103NPPB, FAFNIR GRA103RRB. For 2 designations (RHP 1230-1.3/16ECG, TR GRA206-19G) interchangeability is conditional — the difference usually lies in radial clearance or cage design, so compare the data sheets before fitting.

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.
