Linear Actuators

High-performance contractile artificial muscle actuators

Stronger, Lighter, Smaller

Pound for pound, Adaract’s artificial muscle actuators contract with more force than any other linear actuator–without sacrifices to range of motion, durability, or efficiency.

By combining high pressure hydraulics, advanced synthetic materials, and proprietary manufacturing, Adaract has achieved unprecedented performance in linear actuation. 

Adaract’s actuator performance and how it interfaces with existing systems can be fully customized. An actuator’s length or fiber count can be adjusted, as can its hydraulic fittings and mechanical connections.

high performance artificial muscle actuator

Unparalleled Performance

  1. High Pressure Operation

    Suitable for continuous operation at 3,000 psi, with burst pressures of 9,000 - 10,000 psi

  2. Lightweight Strength

    Contraction force to actuator weight ratios of up to 20,000 : 1 are possible at 3,000 psi. as a standard 8” fiber weighs less than a penny

  3. Compliance

    Well suited for impedance control and as flexible as a shoestring, even in bundles

  4. Zero-drip Operation

    Provides zero-drip operation and compatibility with common aerospace hydraulic fluids such as Skydrol™ and Chemolube®

  5. Durability in Extreme Environments

    Adaract’s actuators can be configured to provide extreme corrosion resistance to salt solutions and humid environments.

  6. Fully Customizable

    Can be designed and manufactured in bundles of any number of fibers at any length to perfectly fit your specific application
