Applicable shaft type: W Both the long shaft and short shaft are shortened. . Applicable shaft type: W Reverse the assembly of the shaft. (Thus shortening the long end and the short end of the shaft.) (If shortening the shaft is not required, indicate “.” for dimension X and Y.) . Applicable shaft types: S, W The long shaft can be further shortened by machining it into a stepped round shaft with a double-sided chamfer. (If shortening the shaft is not required, indicate “.” for dimension X.)(If not specifying dimension C1, indicate “.” instead.) . Applicable shaft types: S, W . Equal dimensions are indicated by the same marker. The short shaft can be further shortened by machining it into a stepped round shaft with a double-sided chamfer. (If shortening the shaft is not required, indicate “.” for dimension Y.) (If not specifying dimension C2, indicate “.” instead.) The long shaft can be further shortened by machining right-angle double-sided chamfer onto it. . Since L1 is a standard chamfer, dimension E1 is 0.5 or more. (If altering the standard chamfer and shortening th shaft are not required, indicate “.” for both the L1 and X dimensions.) . Applicable shaft types: S, W Double key Keys and keyways are machined at 180° from the standard position. . Applicable shaft types: S, W . Equal dimensions are indicated by the same marker.
