Minimum machining diametor for d1 is 0.1. . Applicable shaft type: W Shorten both long and short shafts. . Applicable shaft type: W Symbol: A16 Applicable to single vane type only Size Thread A special end is machined onto both the long and short shafts, and a through hole is drilled into both shafts. Female threads are machined into the through-holes, whose diameter is equivalent to the diameter of the pilot holes. . The maximum dimension L1 is, as a rule, twice the thread size. (Example) For M5: L1 = 10 . Applicable shaft type: W . Equal dimensions are indicated by the same marker. The rotation axis is reversed. (If shortening the shaft is not required, indicate “.” for dimension X, Y.) .
