Schaeffler has developed a fully integrated tandem linear actuator has been developed, measuring a world record-breaking 12 metres in length. The system was developed for a French manufacturer of automation systems.
Schaeffler’s tandem linear actuator with direct drive (designated as F.320086 MDKUSE35-LM, F.320155.MDKUSE35-LM) weighs 1190kg and has a total stroke length of 11,660mm. The system comprises an inherently rigid aluminium support rail with two KUSE35 six-row linear recirculating ball bearing and guideway assemblies arranged in parallel. The system has a positional accuracy of +/- 0.1mm. The width of the carriage is 509mm, with a height of 200mm. The carriage plate is 1570mm in length with a width of 500mm.
The tandem linear actuator provides a maximum acceleration of 1m/s2 and a maximum speed of 0.5m/s. The actuator is driven by a linear motor. The direct drive is equipped with two slotted standard L1C synchronous linear motors that generate a peak force of 4200N.
In 2009, Schaeffler developed a similar system for the same customer application. At the time, the MDKUSE35-3ZR tandem linear actuator was a world record-breaking 8.11m in length, with a total stroke length of 7m and a weight of 800kg.
