Electric cylinders
Electric linear cylinders as an alternative to pneumatic/hydraulic cylinders
Electric cylinders are self-locking. So they do not need energy when they stand still. This makes the electric cylinders to be an interesting alternative to pneumatic and hydraulic actuators. Powerful DC motors, signal lines, potentiometers and Hall-ICs for position indication, as well as integrated end switches uncomplicatedly serve for meeting the most frequent requirements.
Short-stroke cylinders through to heavy-duty linear cylinders available
RK Rose+Krieger has a wide range of electric cylinders, which are divided into different performance classes. From the simple short-stroke cylinder with excellent value for money to the heavy-duty linear cylinder – highly dynamic, extremely precise and individually configurable. With our many years of experience as a manufacturer of electric cylinders, we offer you expert advice and a global service. The standard linear cylinders can be modified following consultation. We are also happy to develop an electric cylinder specially for your particular application – just get in touch!
