About the Airtac SAID200 Double Rod Cylinder SAID200X800
The AirTAC SAID200X800 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical motion. A single piston drives a carbon steel rod out of both end covers, yielding an equal effective annulus area on extend and retract. This design generates 15079 N of force in both directions at 0.5 MPa, completely eliminating the speed and force differential found in single-rod actuators.
Because the rear rod protrudes through the back cover, it provides an excellent mounting point for a secondary cam, position flag, or external guide rail to prevent rotation. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches, though this specific configuration omits the -S magnet. With a PT G3/4 port and adjustable air cushions at both ends, it decelerates massive loads smoothly over its 800 mm stroke.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID200 Double Rod Cylinder SAID200X800 Is Used
Symmetric Press Drive
Drives a heavy press with exactly 15079 N of force on both the extend and retract strokes, ensuring perfectly balanced forming pressure without differential valving.
Twin-Station Actuation
Uses the protruding rear rod to drive a secondary mechanism 800 mm away from the primary tooling, keeping both stations perfectly synchronized from one piston.
Anti-Rotation Transfer Slide
Employs both rod ends to guide a massive transfer carriage over 800 mm, using the twin-rod geometry to prevent rotational twist under high off-center loads.
Is the Airtac SAID200 Double Rod Cylinder SAID200X800 the Right Cylinder?
Selecting this 200 mm bore actuator over a smaller neighbour, like the 160 mm bore delivering 9425 N at 0.5 MPa, is necessary when your application demands up to 15079 N of thrust in both directions. A twin-rod design is chosen over a single-rod SAI when the mechanism requires dual-side guidance, anti-rotation stability, or a rear-rod output for a secondary mechanism. It is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 double-rod cylinders.
At 800 mm of stroke, the unsupported mass of the 40 mm carbon steel rods and piston assembly introduces significant rod-bearing bending and side-load risks. An external guide rail is strictly recommended to absorb lateral forces. Note that a plain SAID does not hold its load when air is exhausted or the valve is centered; the piston will drift. For fail-safe position holding without live pressure, consider the SAIL (air-released lock) or BSAID (double-rod clamp-lock) variants, or integrate an external pilot-operated check valve. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID200 Double Rod Cylinder SAID200X800 FAQ
Because the 40 mm rod occupies both sides of the piston, the effective annulus area is identical in both directions. It delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa for both extend and retract strokes.
Yes. The SAID200X800 is an extruded aluminum profile cylinder with an ISO 15552 mounting interface, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a PT G3/4 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
