HJ318-E-F1
Holding a bearing marked AKN HJ318EU/SQ1 or STEYR HJ318EC/SV1.52? Ours is HJ318-E-F1 — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
HJ318-E-F1 is a L-section ring, execution: open. The manufacturer's cross-reference catalogue confirms full interchangeability for 4 designations, including AKN HJ318EU/SQ1, AKN HJ318EU/SQ1.52, AKN HJ318EU/SQ52.
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.
