Tolomatic IMA Electric Rod-Style Actuators
The IMA integrated motor rod-style electric actuator combines a servo motor with a proven electromechanical actuator design in a compact durable package. Available in both ball and roller screw configurations, the IMA integrated actuator provides high force (up to 3300 lbs with roller screw selection) and reliable, affordable power. Its patent-pending design allows for easy re-lubrication without disassembly for extremely long service life.
