E When combined with other alterations, a phase difference of ±2° may occur. Maintain a clearance of at least 2mm between this alteration and others.
E Although multiple keyways and set screw flats are machined on the same straight axis, a phase difference of ±2° may occur when the total length exceeds 500mm.
*1. When multiple keyways are placed with a clearance of 2mm or less between them, keyways will interfere.
*2. When the keyway position is less than 1mm from the end face, the R angle is not applied.
