IMA Integrated Motor rod-style Actuator Patented LINEAR SOLUTIONS MADE EASY LINEAR SOLUTIONS MADE EASY

The longest lasting, high-force integrated actuator on the market! The IMA is a compact, durable, high force rod-style actuator. The IMA integrates a servo motor into a ball or roller screw-driven actuator to provide efficient high force in a compact lightweight design envelope. Our patented* design allows for easy re-lubrication without disassembly for extremely long service life. Tolomatic has over 50 years of experience manufacturing rodless and rod-style electric and pneumatic actuators. The IMA combines this experience and the power of servo motor technology into one actuator. The...
