Bearing and shaft fit tolerance standard

Bearing and shaft fit tolerance standard ①When the bearing inner diameter tolerance zone and the shaft tolerance zone form a fit, the tolerance code originally belonging to the transition fit in the general basic hole system will become an over-win fit, such as k5, k6, m5, m6, n6, etc., but the over-win amount is not Large; when the bearing inner diameter tolerance is matched with h5, h6, g5, g6, etc., it is not a clearance but an over-win fit.
