Dimensions

• Not all parts are created the exact same size or assembled in precisely the same manner. Therefore, the actual dimensions
of rotary servo motors may be a maximum of approximately 3 mm larger than those in the drawings. In addition, the
described dimensions and dimensional tolerances are the values at 20 °C. Since the values of the dimensions may vary
depending on the ambient temperature, allow some margin when designing the machine side.
• The dimensions are the same, regardless of whether the servo motor has an oil seal or not.
• Use a friction coupling for coupling the servo motor with a load.
• The standard shaft type of the geared servo motors for general industrial machine and for general industrial machine (foot-
mounting) is keyed shaft (with key).
