Product Precautions

[Caution on Product Characteristics]	①The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please see precaution for more details.
	②Dimensions 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.
	③These gears produce axial thrust forces. See precaution for more details.
	④②Due 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.

[Caution on Secondary Operations]	①Please read “Cautions on Performing Secondary Operations” when performing modification and/or secondary operations for safety concerns. Haguruma Kobo, the KHK's system for quick modification of KHK stock gears is also available.
	②Due to gear teeth induction hardened, no secondary operations can be performed on tooth areas including the bottom land (approx. 1 to 2 mm).
