Product Precautions
[Caution on Product Characteristics]  ①Significant variations in temperature or humidity can cause dimensional changes in plastic gears (MC Nylon gears), for bore size (H8 when produced), teeth diameter, and backlash. Please see the section “Design of Plastic Gears” in the technical reference.
 ②Mating 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.
 ③The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please see precaution for more details.
 ④The 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.
 ⑤For 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.

[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.
 ③Plastic gears are susceptible to the effects of temperature and moisture. Dimensional changes may occur while performing secondary operations and during post-machining operations.
