Rotary Actuator Designed for Injection Equipment


Hydraulic Unibody (HUB) series rotary actuator have output torques of 1,800 in-lb to 10,000 in-lb at its maximum operating pressure of 3,000 psi (207 Bar), and address the needs of onshore and offshore fracking operations. They are lightweight, easy to interface, and economically viable. Built to endure weather extremes, the HUB has hard-coat anodized housing, and high-strength alloy steel pinion and racks.The rack-and-pinion gear design provides greater durability than similar splined gears and pushes efficiency  characteristics to 95% while reducing unit size.
