BB = Cap Fixed Clevis Shaded boxes identify required model number fields.
D = Head Trunnion
Limited to 7.00" - 14.00" bore 1 Available mounting styles for K Type cylinders are located at the
DB = Cap Trunnion end of Section B. When ordering a double rod end cylinder, the
Limited to 7.00" - 14.00" bore piston rod number and piston rod end threads are to be specified
for both rod ends.
DD = Int. Fixed Trunnion The model number should be created as viewing the primary rod

Limited to 7.00" & 8.00" bore Example: K Type Cylinder:
7.00CKTD3HLT14A28AC10.000
2 Mounting Styles C and F should have a minimum stroke length
equal to or greater than their bore size.
3 Specify XI dimension.
4 Limited to 7.00" and 8.00" bore.
5 In general, the model numbers as read left to right corresponding
to the cylinder as viewed from left to right with the primary end at
the left. The second or subsequent mountings are mountings called
out as they appear in the assembly moving away from the rod end.
Except when tie rod extension mountings are part of a combination,
all combinations should have a “S” (Special) in the model code and
a note in the body of the order clarifying the mounting arrangement.
The “P”, as used to define a thrust key is not considered to be a
mounting. However it is located at the primary end.
6 Low Friction Piston Seal limited to 7.00" and 8.00" bore.
