LeSS means more. Less weight (up to 40% less than other remote operat- ing gear systems) and less complex installation (single-shaft design) mean more speed, greater payloads and more cost savings (maintenance, repair and opera- tion) for your company. And, our system is remarkably efficient. With as little as 50 ft. lbs. of input you can generate as much as 333 ft. lbs. output torque.

Tested, tried and true. All components are heat resistant, noncorro- sive. Shock- and Vibe-tested. Plus, the Uniflex system is flame tested to API-607 and submergence tested to MIL-STD-810E. Our growing list of satisfied customers speaks for itself—call for references.
