HAMEL, Minn. – The new ERD22 electric rod cylinder from Tolomatic is a low-cost, versatile replacement for pneumatic cylinders and an alternative to manual processes. With force capabilities up to 1,700 lbf (7 kN), the all-300 series stainless-steel ERD22 is a standard catalog item featuring hygienic design and IP69k rating. Ideal for medium-force washdown applications, the ERD22 cylinder is USDA-approved for meat, poultry and dairy applications such as pumping, fluid dispensing, volumetric filling, slicing, cutting and chopping.
“The ERD22 electric rod cylinder rounds out Tolomatic’s product offering for hygienic, USDA-certified and IP69K requirements,” said Nick Holmgard, product marketing engineer, Tolomatic. “It is the smallest of the hygienic group and a perfect performance and cost option for smaller-force requirements than the larger ERD 25 and ERD 30 actuators. As an economical electric actuator platform, the ERD cylinder provides excellent efficiency and operating flexibility over its pneumatic counterparts.”
The ERD in combination with Tolomatic’s ACS actuator control solution creates a complete, low-cost, single-axis linear motion system. The ACS servo controller and servo driver simplifies linear motion with easy setup and infinite positioning with EtherNet/IP™ CIP I/O command. The ACS is ODVA™ conformant.
The Tolomatic family of ERD electric cylinders is now available in seven body sizes, with stroke lengths up to 40 inches (1,016 mm), speeds up to 57.5 inches/sec. (1,460.5 mm/sec.), and forces up to 4,500 lbf (20 kN), depending on the size and screw choice. The product family is available with ball screws, roller screws and acme screws for a variety of cost, force, speed and life options to fit most applications. In addition to food and beverage processing, ERD electric actuators are ideal for a variety of motion control applications including product changeovers, gating/sorting/diverting, pick and place and heat staking/sonic welding.
Built to order and with fast delivery, Tolomatic ERD actuators are designed for maximum durability to extend product service life.
