IMA Linear Servo Actuators
The IMA linear servo actuator includes an integrated servo motor to simplify mechanical designs
The IMA linear servo actuator features a unique integrated servo motor design in a compact, industrial package, that removes the need to source and attach a separate servo motor to the system. Ideal for hydraulic replacement, tight spaces, or when the actuator is exposed to a high level of shock and vibration.
- 4 body sizes with built-to-order stroke lengths and mounting options
- Stroke lengths up to 18 inches (1,524 mm)
- Forces up to 8,000 lbf (35.8 klN)
- Ball and Roller Screw options
- IP67 option to protect against dust and water ingress
