Electric Rod-Style Actuators Offer Increased Force, Load Guidance
Thu, 04/14/2011 - 8:19am
Tolomatic has expanded its line of ERD electric rod-style actuators. New features such as ball screws, motor mounts for NEMA and metric stepper and servo motors, plus a guide option, make it possible to employ ERD actuators in many more types of motion control applications. Originally designed as an affordable replacement for pneumatic cylinders, the ERD is suitable for applications such as product changeovers, pick-and-place, sorting and diverting, and heat-staking. The addition of ball screw choices improves the force range of the ERD up to 200 lb. The combination of NEMA and metric motor mounts allows users to select their preferred brand of servo or stepper motor. All three sizes of the ERD are available with an optional external guide system that prevents rod deflection and rotation during operation. The guide also features a tooling plate for mounting hardware.
