Robust electric cylinders for indoor and outdoor use

Electric cylinders can be positioned very easily and precisely with high repeat accuracy. The linear drives are not only used in indoor applications, but also increasingly in outdoor applications. The solution provider RK Rose+Krieger has recognized this trend. With its LD series, it offers electric cylinders that are suitable for indoor and outdoor use.

RK Rose+Krieger offers a wide range of electric cylinders, from simple short-stroke cylinders with a very good price/performance ratio to heavy-duty linear cylinders. The robust components of the LD series are designed for both indoor industrial applications and outdoor use, for example in the agricultural sector or for mobile machines.

Due to the trapezoidal spindle drive, electric cylinders are self-locking linear drives. This means that no energy needs to be supplied when stationary to keep the electric cylinder in position. Another advantage of electric cylinders is their low-maintenance and leakage-free operation, as they do not require hydraulic fluids or compressed air. The LD series also offers numerous positive features. Their cylinders are designed with protection class IP69K (static) thanks to a special seal. This means that they can also be easily cleaned with a high-pressure steam jet cleaner. They also offer numerous electronic features. Among other things, their stroke and speed can be adjusted. The drives can be conveniently selected and configured using an online tool.

LD series: Compact, robust and powerful

The LD75 electric cylinder is specially designed for use in extreme conditions, such as those found in agricultural machinery, off-highway vehicles, municipal machinery or the offshore sector. Ambient temperatures from -40 to 85 °C are just as harmless to the electric cylinder as the strong vibrations of a construction machine. Thanks to the high protection class of IP69K (static), the housing can even withstand the jet of a high-pressure/steam cleaner without any problems. The LD75 is available for a maximum tensile and compressive force of up to 750 N and a maximum stepless stroke of up to 130 mm at travel speeds of up to 50 mm/s.

The LD1000 linear actuator is a maintenance-free, high-performance actuator of the latest generation, which is available in two variants with protection class IP69K (static). The LD1000C model variant (with controller) has an update-capable controller fully integrated into the housing and is suitable for synchronous operation of several drives, among other things. The identical LD1000E model is equipped with limit switches instead of a controller. The LD1000 is available for a maximum stroke of 1,000 mm and a maximum force of 10,000 N at speeds of up to 156 mm/s. It guarantees safe use in cold and hot conditions between -20 and +65 °C.
