Manufacturers of plant and machin-ery expect high power density, highestdynamics and precision of ControlCylinders – whether in test benches,motion simulators, material or com-ponent testing machines or in seriesmachines that involve sophisticatedclosed-loop controls.
Whether Industrial Cylinders as abasis, High-Performance Cylinderswith extended performance or Servo-Cylinders for demanding applica-tions – Control Cylinders by Rexrothmeet the most stringent requirementsat all performance levels:
· High or extremely low pistonvelocities
· High frequencies· Highest repeatability with integrated
contactlessly position measuringsytems
· Low-friction and virtually stick-slip-free operation
· Absorption of transverse forces onthe piston rod
· High dynamics and system stiff-ness due to the direct attachmentof control valves

The Drive & Control Company.Bosch Rexroth AG offers a uniqueand comprehensive range of productsand services across technologiesfrom a single source in its six fieldsof technology and service areas.
Intelligent hydraulics in new dimensionsAt Rexroth you can select from theworlds’ largest standard productrange in the field of hydraulics, appli-cation-specific and customized spe-cial system solutions of high quality.With advanced micro-electronicsRexroth has made hydraulics evenmore powerful. Benefit from our ap-plication specialists’ expertise –from engineering to the hand-over ofturnkey systems. Thanks to the useof hydraulic drive and control tech-nology from Rexroth you will be morecompetitive than ever.
Rely on service acrosstechnologies.Rexroth integrates all services for theentire product spectrum in the fieldof factory and industrial automationinto a single organization: from imme-diate support, spare parts service, fieldand repair service, retrofit/modern-ization through to training.
