Three in One:Rexroth Hydraulic CylindersStandard, Branch and Project Cylinders

We develop and produce cylinders forvirtually every branch of industry and forevery purpose: Steelworks and rollingmills, foundry machinery, machine tools,general machine construction, presses,plastics processing machinery, civilengineering, wood and paper industry,handling systems, on- and offshore, Three in One:Hydraulic Cylindersfrom RexrothWhether you are integrating Standard Cylinders, Branch Cylinders orProject Cylinders into your overallconcept: All standard series arehighly configurable to an universalconcept, thus enabling you to avoidspecial costly designs. Rexroth maintains actually a minimal numberof standard series, preferring to concentrate on improving special features of variants instead.With Branch Cylinders highly specialized project design engineerswork out customer-specific solutions: These cylinders are designed,tested and then, once ready they areseries-produced in the requiredquantity, all in collaboration withthe customer.Something special – that’s ourstrength: Rexroth develops andproduces Project Cylinders forproject-related individual solutions. We accept virtually everychallenge, realizing cylinders withpiston diameters of up to 1,500millimeters and stroke lengths ofup to 24 meters – and naturallywith the relevant, perfectly matchedwith power units, connection portsand other accessories.

Compact Variety:Standard Tie Rod CylindersThe specific advantages ofRexroth Tie Rod Cylinderscome particularly to the fore inmachine tools and transfersystems for automotive production: They are extremelyshort in their design and, withup to 18 different mountingsavailable, they offer a highdegree of freedom when itcomes to design.The extensive range of Tie RodCylinders from Rexroth in modulardesign comprise a large number ofvariants as well as mountings – andmore. Particularly with demandingapplications an optional, integratedabsolute position measuring systemensures high precision movements.It is space-saving and works innon-contact operation.Even with the development andproduction of Tie Rod CylindersRexroth uses proven methods andtools in the automotive industry.This offers you the security ofreproducible large-scale seriesquality. Self-adjustable end positionVBH “Tie Rod Series”Nominal pressure: 200 barPiston diameter: 25 up to 125 mmStandards:CNOMOcushioning with integrated throttleand check valve function preventsdamage both to the cylinder andthe whole system. Integrated proximity switches record the positionof the piston rod in both end positions. Subplates for control valvessimplify the design of hydraulicaxes for positioning as well as openand closed loop control of thecylinders with minimum cost andeffort.By consistent use of these completesolutions you can reduce complexconversions, and thus also the totalcost of ownership, of your automation solutions.CD70/210 “Tie Rod Series”Nominal pressure: 70/210 barPiston diameter: 25 up to 200 mmStandards:NFPA

Robust and More than the Norm:Standard Mill Type CylindersCylinders for virtually everybranch of industry and for everypurpose: Steelworks and rolling mills, foundry machinery,machine tools, general machine construction, presses,plastics processing machinery,civil engineering, wood andpaper industry, handlingsystems.All Mill Type Cylinder series arehighly configurable to an universalconcept, thus enabling you to avoidspecial costly designs. Rexrothmaintains actually a minimalnumber of series, preferring toconcentrate on improving specialfeatures of variants instead. Thisguarantees swift results to suit you.An optional integrated absolutepositional measuring system ensures maximum precision. Subplates for proportional controlvalves, as well as for SL and SVcheck valves, simplify the positioning, as well as open and closed loopcontrol of the cylinders, with minimum cost and effort.All cylinders are as clear and constructive in their assembly as theyare precise in their design: Rexrothcylinders have an precision-drivenpiston rod combined with thelatest bearing and sealing systems.Its robust design makes RexrothMill Type Cylinders especiallyreliable, even under extreme working conditions.CDL1 “Light Series”Nominal pressure: 160 barPiston diameter: 25 up to 200 mmStandards:Bosch Rexroth StandardCDM1 “Medium Series”Nominal pressure: 160 barPiston diameter: 25 up to 200 mmStandards:ISO 6020/1

Individual Series:Branch CylindersHighly specialized cylinderdesign engineers engagethemselves in working outcustomer-specific solutions:Special Branch Cylinders aredesigned, tested and produced in series, all in collaboration with the customer.Hydraulic drive systems controlthe angle of incidence of the rotorblades in wind turbines in robust,reliable and maintenance free way.The machine manufacturer setsthe task and Rexroth designs theideal electrohydraulic linear drive– hydraulic cylinder, compactcontrol block, control valve anddigital axis controller – all from asingle source.For this branch solution togetherwith the customer Rexroth developed a solution based on StandardCylinders exactly to the requirements and optimally combinedwith matched control components.And this is where your know-how,combined with that of Rexroth,really counts: This is becauseOnly with a predefined process and close co-operationbetween the customer, application specialists and cylinderdevelopers it is possible torealize innovative and branchspecific solutions.Ready forseries productionevery application demands tailormade concepts. Rexroth developsstate-of-the-art solutions, workingtogether with you as trustworthypartner as well as with leadingresearch institutes.We naturally place great emphasison protecting your interests. Thisalso includes the consistent application of the latest quality methodsin the development and productionof your Branch Cylinders. Withsimulation programs that we havedeveloped we can calculate at anthe early stage the parameters required, thus offering you the highest level of safety in drive design.We configure complete, ready-touse axes to your specifications.Precisely: Individuality in series.Producedeliveryplan to meetdeadlinesCustomerZero finitionDraw upconceptPrototypephaseProjectphase
