Electromechanical Cylinders Combine Power With Efficiency

Rexroth says that its electromechanical cylinders bring custom control, high speed, high torque capability to applications traditionally requiring hydraulic or pneumatic cylinders. The company says EMC cylinders are energy efficient and environmentally friendly, with versatile configuration options.

The new series of Electromechanical (EMC) cylinders are designed to provide high thrust, high speed capabilities with greater flexibility and control to applications traditionally using hydraulic or pneumatic cylinders. The company states that the EMC cylinders' combination of power, speed and corrosion-resistant construction, makes them ideally-suited to applications in packaging and material handling, assembly and robotics, metal forming, and more.

The EMC cylinders contain a precision-rolled ballscrew actuator, providing high positioning accuracy and repeatability while eliminating the "stick-slip" effect. The low maintenance drives are said to be highly efficient, reducing energy costs and offering an environmentally friendly alternative to hydraulics.

EMC cylinders are available in six sizes ranging, with stroke legnths of up to 2,000 mm, and speed capabilities of up to 1.6 m/sec. Each unit is rated to an IP65 degree of protection. The EMC cylinders feature identical connection dimensions with ISO 15552 pneumatic cylinder standards and can be seamlessly integrated into traditional pneumatic applications. The EMC cylinders' versatility allows for both direct and parallel motor mounting options, numerous rod end, flange, trunnion and clevis mounting options, and a selection of step- and servomotors with various performance profiles.
