(side fit), where the tooth flanks transmit torque and center the components. Deviation Series: a through g (shafts) and (hubs) provide slip fits. Position is a "line-on-line" fit, while j through v (shafts) and J through M (hubs) provide interference fits. Tolerance Grades: Ranges from 5 (tightest) to 12 (loosest). 4.
