• A 5-phase stepping motor is mounted directly onto the end of a KSS ball screw with a diameter of 4 mm, 6 mm, 8mm, or 10 mm, lead of 1 mm, 2 mm, or 4 mm, and a C3 accuracy grade. The KSS-ball screw shaft is ideally constructed to form the motor rotor shaft.
  
• Precision positioning mechanisms can be achieved without the need to center the motor and screw shaft, reducing labor.
  
• The direct coupling system eliminates the need for a shaft joint, allowing for reduced axial dimensions and minimizing lost motion.
  
• This simple yet high-performance positioning unit uses KSS ultra-precision miniature ball screws, and makes full use of ball screw performance by precision manufacturing technology based on precision positioning expertise.
  
• A wide range of series and stroke specifications is available, fitted with a range of KSS screw threads starting at an ultra-compact size that fits in the palm of the hand, with 4-mm diameter ball screws, 24-mm external motor dimensions, and a total length of 104 mm.
  
• Uses high-performance five-phase stepping motors. Provided with drivers and control equipment.

Core products in electrical actuator range are environmentally friendly, easy-to-use, and labor-saving. New block unit devices that perform positioning work “straight out of the box” in a variety of
fields, such as:


• Lightweight drive work within limited spaces for all types of positioning and drive units
  
• Small-stroke, high-speed positioning, and drive units
  
• Ultra-high precision fluid “dose” control mechanisms
  
• The Z-axis function on XYZ robots or circuit board soldering robots
