Product Precautions
[Caution on Product Characteristics]  ①Worm Wheels are profile shifted to create the proper center distance.
 ②The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please see precaution for more details.
 ③Since the bore is finished with a minus tolerance, you can use a shaft with a force fit

[Caution on Secondary Operations]  ①Please read “Cautions on Performing Secondary Operations”when performing modification and/or secondary operations of Worm Gears. Haguruma Kobo, the KHK's system for quick modification of KHK stock gears is also available.
