Your Benefits

Dynamic and flexible
High end speeds and complex motion profiles for short cycle times—even under heavy loads.

Digital
Easy startup and reduced installation effort between hardware components with MOVILINK® DDI.

Combinable
With synchronous servomotors in two sizes and multiple belt transmissions. Maximum flexibility and adaptability in terms of dynamics, braking torques, or holding forces.

Modular electric cylinders for every application and various travel profiles

Applications involving linear motion often place high demands on the motion profile. Our new LM3S.. series electric cylinders are particularly well-suited for linear motion with high accelerations and speeds—ideal for applications with demanding motion profiles and high precision. The LM3S.. series is gradually replacing our successful CMS.. series and, as the third generation of electric cylinders, builds on our experience in this field.

Using adapters, the linear unit can be combined with the entire CM3.. motor modular system as well as our CMP.. series synchronous servomotors. Thanks to the flexible adapter concept and the open motor interface, servomotors from a wide variety of manufacturers can also be easily integrated. The system can be scaled to a force range of up to 26 kN.
