Note 2) Spring return up to 18" available as special request. Note1) Force on extension (OUT) is shown as the theoretical force of a double acting non-rotating rod cylinder on extension less the compressed force of the return spring. Note 2) Force on retraction (IN) is the resting force of spring when fully retracted.
