Please see page 283 for more details.② Dimensions of the outside diameter, the overall length and crown to back length are all theoretical values, and some differences will occur due to the corner chamfering of the gear tips.③ These gears produce axial thrust forces. See Page 284 for more details.④ Due to heat treating, some deformation of the bore may occur. It may be necessary to ream the bore to bring it to the stated dimensions.*For products not categorized in our KHK Stock Gear series, custom gear production services with short lead times is available.
