What are the uses of a clearance fit?

A clearance fit is used when you want two parts to slide, move, or rotate against each other without sticking or binding. You’ll see it in things like shafts and bearings, bolts and holes, or any assembly where one part needs to fit into another with a little extra space.

The purpose is to make assembly easier, reduce friction, and allow for movement where it’s needed. Clearance fits are common in mechanical designs where smooth operation, easy installation, and simple disassembly are important.
