BACK-TO-BACK CYLINDERMax Operating Pressure: 250 PSI (17 bar)
Bore Size: 1.5 to 8 (38 to 203 mm)
Any TRD Manufacturing cylinders can be ordered back-to-back − mixed or matched, to provide unlimited design possibilities.
Back-to-back cylinders consist of two (2) individual cylinders having common bore sizes, built as one unit utilizing common tie-rods. Mounts include a full range of base, tie-rod and head or cap trunnions for pivot mounting.
(Tip: A rod clevis can be used on each piston rod to create additional pivot mounting styles).
MULTIPLE POSITION CYLINDER
The back-to-back design creates a true four-position cylinder. By varying stroke lengths, a multitude of positions can be created. (Example: CYL 1 has a 1” stroke; CYL 2 has a 2” stroke. The stroke positions would be: 0”, 1”, 2” and 3” depending on how the cylinder is cycled).
HARD POSITION STOPS
Unlike a three-position cylinder, a back-to-back cylinder provides hard stop positioning (Note: Three-position cylinders rely on the back piston rod to push against the front piston rod to create the intermediate position. Care must be used to prevent the front piston rod from extending in the intermediate position).
ECONOMICAL DESIGN − The back-to-back design uses standard parts, reducing overall costs.
