2 Series 2H Cylinders keep on performing like youexpect from Parker producing more power perpound, more power per dollar over millions oftrouble-free cycles. Everything you need for reliable3,000 psi performance. Patented Jewel rod glandfor longer life and lower operating costs. Chrome-plated, case hardened piston rods. Rod end studs ofhigh yield-strength steel, with rolled threads for addedstrength. Tie rods with rolled threads and steel cushions with float-check action and positivemetal-to-metal seal.

Parker cylinder cushions are astepped design and combine the best features of known straight or tapered cushions have been used in industrialcylinders over a very broad range of applications. Parker researchhas found that both designs have their a result, Parker has taken a new approach in cushioning ofindustrial Hydraulic Cylinders and for specific load and velocityconditions have been able to obtain deceleration curves that comevery close to the ideal.

7 The success lies in a stepped sleeve orspear concept where the steps are calculated to approximatetheoretical orifice areas the cushion performance chart, pressure traces show theresults of typical orifice flow conditions. Tests of a three-stepsleeve or spear show three pressure pulses coinciding with thesteps. The deceleration cushion plunger curves shape comes veryclose to being theoretical, with the exception of the last 1/2 inch ofPiston Rod Stud Furnished on 2" diameter rodsand smaller when standardstyle #4 rod end threads arerequired or on 13/8" diameterrods and smaller when style#8 threads are required.
