Product Precautions
[Caution on Product Characteristics] ①The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please see Selection Hints for more details.
②10- and 11-tooth gears with module over 1.5 are profile shifted gears (x = +0.5). Please refer to “Profile Shifted Gears” in the technical reference for calculating the center distance when assembled.
③The backlash values shown in the table are the theoretical values for the normal direction for a pair of identical SS Spur Gears with 30 teeth in mesh.

[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.
