Introduction to Electromechanical Cylinders

Electromechanical Cylinders (EMCs) are a high-performance alternative to traditional hydraulic and pneumatic cylinders. The EMC’s main component is the Ball Screw Assembly (BSA), which converts torque from the Servo Motor to linear motion. The drive nut on the BSA then actuates forward and backward along the shaft, without rotation. Thanks to Bosch Rexroth’s plethora of configuration options, the EMC can be configured to fit many applications, with a high level of energy and mechanical efficiency.
