I have an inside diameter (9.928mm UL) that I have to measure that gets a bearing shaft installed into it. I actually refer the hole as a cylinder because it’s about 25mm deep. I have been arguing with the production manager that we can use a 9.928 (a 1" pin won't go into a 1" hole) pin to check the upper limit (UL) because of the interference fit. Even though the pin is a minus (9.926mm) I'm afraid that the holes are still too big.
What is the formula to figure the interference fit and what should be used to determine the actual UL pin to be used.
