Accuracy of housing with housing

by:JNSN     2021-12-12
The accuracy of the bearing housing for rolling bearing with housing refers to the allowable deviation and allowable value of the diameter of the spherical bearing housing matched with the bearing and the allowable deviation and allowable value of the installation-related dimensions of the bearing housing. The allowable deviation of the ball bearing seat diameter of the bearing box is shown in Table 11.7. Bearing housing for rolling bearing with seat, the matching of bearing housing and bearing adopts tolerance zone grade J7 which can form transitional fit. A representative example of installation-related dimensions with allowable deviations and allowable values u200bu200bof the bearing box is shown in Figure 11.1. The allowable deviations and allowable values u200bu200bof the relevant dimensions of the bearing box installation are shown in the respective dimension tables. Installation related dimensions (representative example) with allowable deviations and allowable values u200bu200bfor bearing housings with seats (Remarks) The allowable deviations and allowable values u200bu200bof the bearing housings are listed in the dimension table. The general dimensional tolerances of cutting and as-cast parts that are not specified in this catalog are shown in Table 11.8. The free dimensional tolerance items of each unspecified part are standard number grade. Cutting process JIS B 0405 Intermediate cast iron castings JIS B 0403 standard cast iron castings JIS B 0403 standard cast steel castings.
