Airtac SAID200 Double Rod Cylinder SAID200X900
The AirTAC Airtac SAID200 Double Rod Cylinder SAID200X900 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning.

About the Airtac SAID200 Double Rod Cylinder SAID200X900
The AirTAC SAID200X900 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical actuation. Because a carbon steel rod exits both ends, the annulus area is identical on extend and retract, yielding an equal 15079 N of force in each direction at 0.5 MPa. This through-rod design allows one end to drive the primary workpiece while the opposite rear rod end operates a secondary mechanism or position flag.
As a non-standard 900 mm stroke variant (exceeding the 1500 mm standard maximum is not the case here, but 900 mm requires made-to-order attention for large bores), it features a G3/4 port and adjustable air cushions at both ends to decelerate the massive load near stroke end. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches, though a magnet is not specified for this base unit.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |

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 SAID200X900 Is Used
Heavy-Duty Symmetric Press
Drives a large forming die with equal 15079 N force on both the extend and retract strokes, ensuring perfectly balanced press cycles without rotational drift.
Dual-Station Transfer
Uses the through-rod design to move a primary workpiece on the front end while simultaneously actuating a secondary conveyor indexing mechanism on the rear rod end.
Anti-Rotation Guiding
Leverages the twin-rod architecture to keep a massive 200 mm bore load perfectly guided across a 900 mm stroke, preventing the twisting moments common to single-rod actuators.
Is the Airtac SAID200 Double Rod Cylinder SAID200X900 the Right Cylinder?
Selecting the SAID200X900 is optimal when an application demands immense bidirectional force (15079 N at 0.5 MPa, scaling to 27141 N at 0.9 MPa) and strict anti-rotation guidance. If the 900 mm stroke overshoots your space constraints, stepping down to the SAID200X800 provides a standard length, while dropping to a SAID160X900 reduces the both-way force to 9425 N at 0.5 MPa. Remember that a plain SAID does not hold its position when air pressure is lost; for dead-load holding, consider the SAIL or BSAID clamp-lock variants.
At 900 mm of travel, the long unsupported piston rod is highly susceptible to side-load bending and rod-bearing wear; an external guide rail is mandatory to prevent premature seal failure. This unit is dimensionally interchangeable per ISO 15552, offering a direct replacement for other ISO 15552 double-rod cylinders. Mounting options are restricted to the SAID set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting the FB, CA, CB, and CR styles used on single-rod SAI units).

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 SAID200X900 FAQ
Because the double-rod design creates equal annulus areas on both sides, the SAID200X900 delivers 15079 N of force in both the extend and retract directions at 0.5 MPa, and up to 27141 N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552, but the SAID series uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR accessories found on single-rod variants.
