ERD Electric Rod-style Actuator Challenges Pneumatic Cylinders Tolomatic, TOL-O-MATIC
The ERD electric rod-style actuator is available in body sizes that are equivalent to 5/8”, 1” and 1.5” bore non-repairable pneumatic cylinders. The ERD can be orderd in stroke lengths up to 8, 10 and 12 inches, respectively, and accommodate forces up to 20, 40 and 75 pounds. The three sizes, from small to large, accept NEMA 11, 17 or 23 frame stepper and servo motors. The acme lead screw is available in three lead sizes per size to optimize speed or force.
ERD products are round bodied, following the footprint of most pneumatic actuators in this performance class. The rear head of the actuator features an oversized main bearing to accommodate high thrust loads and provide long life. The main tube and thrust tube are made of stainless steel for high rigidity and corrosion resistance, while the metric-threaded nose mount accepts a jam nut that provides convenient mounting for many applications. Mounting options include a rear trunnion mount, foot mounts or a front flange mount.
