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 SSG 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.
 ②Due to gear teeth induction hardened, no secondary operations can be performed on tooth areas including the bottom land (approx. 2 to 3 mm). Use carbide tools for the modification of the shaft area near the bottom land.
