Tolomatic ERD electric actuators

Tolomatic’s ERD electric cylinders are now available in six body sizes, expanding the force range from 2.22 to 20.03 kN. The actuators are suitable for a variety of motion control applications, including washdown environments, product changeovers, diverting/sorting, pressing and heat-staking/sonic welding. The ERD25 and ERD30 hygienic designs are USDA certified for meat (livestock), poultry and dairy processing applications.

The ERD electric cylinder family is available in stroke lengths up to 1.016 m, speeds up to 1.46 m/s, and forces up to 20.03 kN, depending on the size and screw choice. They are available with ball screws, roller screws and acme screws for a variety of cost, force, speed and life options to fit most applications. The ERD is also compatible with most third-party servo and stepper motors (NEMA and metric). All six sizes of the ERD are available in 300 series stainless steel and with IP67 or IP69k options.

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 clevis, rear trunnion mount, foot mounts or a front flange mount.

The ERD actuators can accommodate six different sensing or switching choices: reed, solid state PNP (sourcing) or solid state NPN (sinking), normally open, flying leads or quick disconnect.
