Caution on Product Characteristics] ① Significant variations in temperature or humidity can cause dimensional changes in plastic gears (MC Nylon gears), including bore size (H8 when produced),

tooth diameter, and backlash. Please see the section “Design of Plastic Gears” in separate technical reference book.  

② The allowable torques shown in the table are calculated values according to the assumed usage conditions. Please  ask for more details.

③ When the core O.D is the same as the hub diameter, you may see some serration on the hub. There is no effect on the strength of the gear.

④ Without lubrication, using plastic gears in pairs may generate heat and dilation. It is recommended to mate them with steel gears.

⑤ The 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
