Product Precautions
[Caution on Product Characteristics]  ①Although the sintering process allows for the inclusion of oil to maintain lubricity, these gears have not been oil impregnated.
 ②The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please see Selection Hints for more details.
 ③The 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.
 ④Since 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 for safety concerns. 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.
 ③The rust prevention process involves treating the gears with steam (in effect, creating surface oxidation). A black oxide treatment cannot be done on these gears.
