The characteristics of the rolling bearing to cooperate

by：Waxing 2020-11-16

1) Rolling bearing inside diameter d, diameter d is bearing and shaft, bearing and the shell bearing hole ( Bearing chamber) Cooperate with the nominal size. Inside diameter d base hole system, but its tolerance zone located below the zero line, the upper deviation is zero, the deviation of negative. With other base hole system tolerance zone is located in the above the zero line, compared to more available in conjunction with the same name cooperate more closely. Diameter D shaft basis, but the tolerance zone is the same as other shaft basis, located above the zero line, the upper deviation is zero, the deviation of negative. Bearings with holes are loose, compared with other shaft basis with the same name, the tolerance zone is not exactly the same. Below for a variety of precision grade bearing tolerance zone distribution diagram. 2) Match the parts ( Shaft and hole) Machining precision of general to and the precision of the bearing. Considering the shaft and housing holes on the precision of the bearing has different effect, and the ease of processing, general axis machining precision bearing at the same level or higher accuracy; And the shell hole machining precision bearing even at the low level of accuracy. In general, and the accuracy of 0 and 6 match the bearing of the shaft and hole tolerance grade IT6 and IT7 respectively.
