What is tolerance h6?
For a shaft of the same size, h6 would mean 10+0−0.009, which means the shaft may be as small as 0.009 mm smaller than the base dimension and 0 mm larger. This method of standard tolerances is also known as Limits and Fits and can be found in ISO 286-1:2010 (Link to ISO catalog).
How much should my press fit tolerance be?
Press-fit holes are plated through holes with tighter tolerances than the standard +/-0.10mm. Press-fit holes fit the leads of connectors that will not be soldered but pressed into the holes. To accommodate lead and hole to tightly fit together, the tolerances are well defined and more tight than standard.
What is the tolerance for the shaft diameter?
Shaft tolerances should be within ±0.05 mm (±0.002 in) and where PTFE wedge packings are used must be round within 0.01 mm (0.0005 in).
What is H7 g6 tolerance?
F8/h7. Close running fit for running on accurate machines and for accurate location at moderate speeds and journal pressures. H7/g6. G7/h6. Sliding fit not intended to run freely, but to move and turn freely and locate accurately.

What is a normal press fit?
In engineering terms, a press fit— also known as an interference fit— is the fastening of two parts that is achieved by normal force, friction and cold welding. This happens when a shaft is inserted tightly into a slightly smaller hole in another part, with the interference holding both parts in place.
How much smaller should a press fit hole be?
How much larger the inserted part needs to be relative to the hole will vary, although typically it’s 0.0005 to 0.002 inch. Mike Brieschke, vice president of sales at Aries Engineering, says a 0.25-inch-diameter metal dowel that is press-fit into a mild steel hole usually has an interference of ±0.0015 inch.
