e-F@ctory Alliance Products
Harmonic Drive is proud to be an e-F@ctory Alliance partner. We look forward to working with you and are happy to offer our precision rotary actuators and servo gearboxes.
Harmonic Drive® rotary actuators are the easiest solution for your high precision motion control applications, and we integrate seamlessly with Mitsubishi MELSERVO-J4 SSCNETⅢ/H Servo drives. Performance matched precision gearing, motors, and encoders are designed to provide a power dense, cost effective solution. SHA-xx-M hollow shaft rotary actuators are available in many sizes with gear ratios ranging from 11:1 to 161:1.
Also available are our planetary and harmonic Quick Connect® servo mount gearboxes. These gearboxes are equipped with our Quick Connect® coupling, enabling our gearboxes to connect easily to any Mitsubishi MELSERVO-J4 motor. We offer these easy-to-connect gearheads in many sizes and configurations, with a range of gear ratios and torque capacities.
See our product lines below especially designed to work with Mitsubishi MELSERVO-J4 servos. Or simply use our gearhead matching tool to find the right gearhead for your MELSERVO-J4 drive.
