Electric rod-style actuator

Nov. 7, 2013
The ERD line of electric rod-style actuators now comes in six body sizes, expanding the force range from 500 to 4,500 lbf (2.22 to 20.03 kN). The actuator is designed as an alternative to pneumatic cylinders and an option for automating manual processes. The ERD25 and ERD30 hygienic designs are USDA certified.
The ERD line of electric rod-style actuators now comes in six body sizes, expanding the force range from 500 to 4,500 lbf (2.22 to 20.03 kN). The actuator is designed as an alternative to pneumatic cylinders and an option for automating manual processes. The ERD25 and ERD30 hygienic designs are USDA certified.

The cylinders come in stroke lengths up to 40 in. (1,016 mm), and speeds to 57.5 ips (1,460.5 mm/sec), depending on the size and screw choice. The product family is available with ball screws, roller screws, and Acme screws. The motors can be mounted in-line with the actuator or in a reverse-parallel motor mount.

The rear head of the round-bodied actuators features an oversized main bearing to accommodate high thrust loads and provide long life. The stainless-steel main tube and thrust tube provide corrosion resistance, and the metric-threaded nose mount accepts a jam nut for mounting. Mounting options include a rear clevis, rear trunnion mount, foot mounts, or a front flange mount.

The actuators accommodate six different sensing or switching choices: reed, solid-state pnp (sourcing), or solid-state npn (sinking), normally open, flying leads, or quick-disconnect. The switches are activated by a standard, internal magnet located inside the thrust tube.
