Specifications subject to change without notice or incurring obligation 5 Multi-Power ® Cylinders When required return forces (Extend or Retract) are greater than the standard single piston can provide, multiple stages (pistons) can be pressurized. This is accomplished by replacing one or more of the standard baffles with a ported baffle as shown in the illustration. When these thicker baffles are used, the overall length (“Dimension A”) increases. See the chart below for port size and dimension details. Multiple Stages Extend & Multiple Stages Retract (Not available on 10" and 12" bores) 5-22-13 No. of Total Available Ported No. of Combinations Baffles Stages 2 X 2 1 2 3 X 2 1 3 3 X 3 2 3 2 X 3 1 3 4 X 2 1 4 4 X 3 2 4 4 X 4 3 4 3 X 4 2 4 2 X 4 1 4 Notes: When any of these combinations are ordered, the proper number of ported baffles are included. As standard, the largest number of stages are internally connected. On models with the same number of extend and retract stages, the extend stages are internally connected.

The ports have higher air flow capacity than the vents in the standard baffle. With control circuitry, the number of stages that are pressurized (thus the amount of force being applied) at any given time can be selected and varied. Consult engineering with application details. Male Rod Thread Option Single Rod -MR Double Rod, Rod End Only -MR Double Rod, Cap End Only -MR1 Double Rod, Rod & Cap Ends -MR2 For bores 1-1/8" thru 8", a high strength stud is threaded into the standard female rod end and retained with Loctite ® . This method eliminates the small diameter thread relief area normally required when machining male threads. This provides a much stronger Thread rod end which can be repaired, rather than replacing the complete rod, should the thread be damaged. For 10" and 12", the thread is machined integral with the rod.
