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.

[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.
