About the MP-Series Heavy Duty Electric Cylinders
MP-Series™ electric cylinders feature multi-turn high resolution encoders and are available with
24V DC brakes. The MP-Series motor drives a ball screw or roller screw that converts rotary
motion into linear movement. The linear motion extends or retracts the thrust rod within the
electric cylinder housing.
The MP-Series electric cylinders have been designed for exact positioning at high speeds.
IMPORTANT The MP-A/Bxxxxxx2x electric cylinders are non-braking. When there is no input torque, the
thrust rod can be moved freely. To achieve self-locking of your motion system, use an electric
cylinder with an integrated brake (catalog number MPAI-A/Bxxxxxx4x).
