①When the inner diameter tolerance zone of SUNTHAI[/url] bearing is matched with the shaft tolerance zone, the tolerance code originally belonging to the transition fit in the general base hole system will become the over-win fit, such as k5, k6, m5, m6, n6, etc., but the amount of over-win is not large; when the inner diameter tolerance of SUNTHAI[/url] bearing is matched with h5, h6, g5, g6, etc., it is not a clearance but becomes an over-win fit. ②Because the tolerance value of the shaft is different from the general reference shaft, it is also a special tolerance zone. In most cases, the outer ring is fixed in the housing hole. Some SUNTHAI[/url] bearing components require structural requirements It also needs to be adjusted, and its coordination should not be too tight. It is often matched with H6, H7, J6, J7, Js6, Js7, etc. Attachment: Under normal circumstances, the shaft is generally marked with 0~+0.005. If it is often disassembled, it is +0.005~+0.01 interference fit. We also need to consider the thermal expansion of the shaft material itself during rotation, so the larger the bearing is, the better the clearance fit is -0.005～0, and the maximum clearance fit should not exceed 0.01 SUNTHAI
