Fast, High Force IMA Actuator Fills High Duty Cycle Need

Company Name: 

The compact, heavy-duty Tolomatic IMA integrated linear servo actuator is now available with additional ball screw offerings that more than double the speed range, from 24 inches per second (610 mm/sec) to 58 inches per second (1,473 mm/sec). The IMA is CE/UL approved.

Designed for long life in high duty cycles, the IMA delivers high force in press fitting systems; accurate positioning and quick response in valve and process control; compact, lightweight spot welding; and smooth velocity fluid dispensing. When designed with food-grade white epoxy coating and stainless steel components (available as catalog orders), the IMA provides corrosion resistance, ingress protection and bacterial growth protection for food and beverage industry applications.

The IMA integrates a servo motor into a ball or roller screw-driven actuator to provide efficient high force in a compact, lightweight design. The IMA55 high-force servo linear actuator with roller screw option boosts its thrust capability to 6,875 pounds force (30,470 N). The patented long-life design eliminates the need for couplers, adapters, belts and gears and allows for easy re-lubrication without disassembly.

Available in four sizes, the IMA line of integrated-motor rod actuators features stroke lengths from three to 18 inches (76.2 to 457.2 mm).

“The IMA’s hollow-core rotor design allows the nut of the screw to pass inside the rotor, creating a very compact package,” said Aaron Dietrich, marketing manager, Tolomatic. “This decreases overall actuator length compared to standard actuators due to the elimination of a separate motor, motor mount and gearbox. Tolomatic’s sizing and selection software makes selecting an IMA actuator easy.”
