K-Type Cylinders | NFPA 4MAJ Series Rod Lock Option - 1-1/2" to 5" Bore Sizes | Tie Rod Cylinders | Pneumatic Actuators

To determine dimensions for a double rod end cylinder, first refer to the desired 4MA small bore single rod mounting style. After selecting the necessary dimensions, return to this page and supplement the single rod end dimensions with those shown in the table below. Please note that double rod end cylinders have a head dimension G at both ends, and that LG replaces LF, PK replaces P, etc. The double rod end dimensions differ from, or are in addition to, those for single rod cylinders. When a double rod end cylinder has two different rod ends, please clearly state which rod end is to be available at which head end.
