CAUTION: Significant variations in temperature or humidity can cause changes in plastic gears (MC Nylon gears). Please see the section on plastic gears in the technical section for additional information.

NOTE: The allowable torques shown in the table are calculated using the Lewis formula. The backlash values shown are the theoretical values of a pair of identical gears in mesh. All dimensions shown in the above table(s) are listed in millimeters unless otherwise specified.
