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.
 ②The backlash values shown in the table are the theoretical values for the backlash in the normal direction of a pair of identical gears in mesh.
 ③These gears produce axial thrust forces. Please see precaution
 ④Right-handed and left-handed helical gears in the same module are designed to mesh as a pair, but they are not interchangeable with KHG type helical gears, as these products are of the normal module.

[Caution on Secondary Operations]  ①Please read “Cautions on Performing Secondary Operations”when performing modification and/or secondary operations of Helical Gears. Haguruma Kobo, the KHK's system for quick modification of KHK stock gears is also available.
 ②Avoid performing secondary operations that narrow the tooth width. as it affects precision and strength.
