Product Precautions
[Caution on Product Characteristics]  ①Mating screw gears are made of the same material and may cause abrasion and scoring. It is recommended to mate Screw Gears composed of different materials.
 ②The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please see precaution 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.
 ④For offset shaft applications, match a RH with a RH, or LH with a LH , meshed to make a set of screw gears. For parallel shaft applications, mesh opposite hands (RH and LH) of helical gear sets. See precaution for more details.
 ⑤If the bore size is less thanφ4, the tolerance class is H8. If the bore size is φ5 orφ6, and the hole length exceeds 3 times of the bore size, the class is also H8.

[Caution on Secondary Operations]  ①Please read “Cautions on Performing Secondary Operations”when performing modification and/or secondary operations of Screw 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.
