The rod end rod is Hex and the cap end rod is round. The ported baffles are included and the “Dimension A” adjustments shown for Option –NR must be made. Extended piston areas must also be reduced by the rod area.

Consult engineering for compatibility information. Double Rod Option -DR Standard piston rod and rod bushing on both ends of the cylinder. For 8" bore only, when -KF is specified, 1"–14 threads will be applied at both ends. Use when attachment to both ends of the cylinder is required, or to indicate piston position. Also see Option –E on page 5.12. H + stroke See page 5.5 for dimension “H”. Typical for ALL bores and ALL mounting styles. Note: 10" & 12" Bores for Position Indication Only– Rod Thread 3/8-16 x 5/8 Deep 5.8 See page 5.5 for Dimension “A” A stainless steel hex rod and a hex broached bushing of SAE 660 bearing bronze replaces the standard round rod and bushing. A ported baffle is used so the piston assembly can be retracted by the next piston back from the rod end. The normal rod head port becomes an atmospheric vent. The tolerance on rotation is ±1°. The hex rod design does allow for some torque loading on the shaft. However, torque loads that induce side loading should be minimized for best overall life and performance.
