Assembly

Assembly Tolerance

See the dimension and the geometric tolerances of the input, output and the housing when applying DYD on the system.

Assembly Tolerance

Assembly example of PG option

The PG option that provides high ratio reduction, requires a bracket to attach the motor to the apparatus. The bracket for a motor is not provided.
