H7/h6 fits.
ISO 286.
Mating tolerance.
Tolerances and fits reference. ISO 286 hole-and-shaft system. Press fits, slip fits, running fits. Standard fits for engineering applications.
Key principles.
H7 baseline
Hole H7 (positive deviation, 0 to +X). Shaft varies.
h6 baseline
Shaft h6 (negative deviation, 0 to -X). Hole varies.
H7/p6
Standard press fit. Permanent assembly.
H7/g6
Sliding fit. Easy assembly, no clearance.
H7/f7
Running clearance fit. Rotating shafts.
H7/d10
Free running clearance fit.
FAQ
Hole-basis vs shaft-basis?
Hole-basis common for machined holes. Shaft-basis for ground shafts. Same outcome.
H7/p6 specifics?
H7 hole 0 to +0.025 mm (10 mm shaft). p6 shaft +0.014 to +0.026 mm. Press fit interference.
Class names?
Press fits, slip fits, running fits, free fits. Each has specific clearance/interference range.
Standard fit selection?
Bearing bores H7/h6 typical. Slip fits H7/g6. Press fits H7/p6 or n6.
GD&T vs ISO 286?
GD&T defines feature relationships. ISO 286 defines hole-shaft fits. Use either.
Specifying on drawing?
Note "10 H7" for hole, "10 p6" for shaft. Mating dimensions implied.
