When choosing actuators, linear systems such as electromechanical cylinders are increasingly gaining in importance compared to fluid power drives.
Electrical cylinders or electromechanical cylinders offer the highest degree of energy efficiency with a maximum degree of efficiency. With a tensile and compressive force of up to 290 kN per axis, the drive energy is transmitted safely and precisely.
The drive mechanism of the electric cylinder is based on a powerful linear screw assembly which is available in many different diameter and lead combinations. The ball screw assembly or planetary screw assembly converts a rotary torque into a linear motion with a high level of efficiency. The piston rod attached to the threaded nut is extended and retracted.
Electromechanical cylinders of the EMC and EMC-HD series from Bosch Rexroth are a high-performance alternative to pneumatic or hydraulic cylinders. In addition to the aspect of energy efficiency they score top marks with clear design advantages, as any intermediate positions can be traveled to and higher forces and travel speeds can be achieved.
