Lovejoy, Inc. Customary Metric / Clearance-fit and Interference-fit _Bore and Keyway Standards

Lovejoy

Lovejoy, Inc. Customary Metric Clearance-fit and Interference-fit Bore and Keyway Standards (millimeters) Keyway Tolérances per ISO 286-2

Lovejoy, Inc. assumes H7 tolerances as standard clearance and P7 tolerances as standard interference fits if shaft and/or bore tolerances are not specified.
