KH40-PP
Holding a bearing marked SKF LBBR40-2LS or KORB KH40x52x60-PP or NADELLA KH4060-UU? Ours is KH40-PP — the same seat size, the same type and the same sealing and clearance design.
What this bearing is
KH40-PP is a Linear Ball Bearing, execution: open. The manufacturer's cross-reference catalogue confirms full interchangeability for 3 designations, including SKF LBBR40-2LS, KORB KH40x52x60-PP, NADELLA KH4060-UU.
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.
