About the Airtac SAID200 Double Rod Cylinder SAID200X350S
The AirTAC SAID200X350-S 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 identical annulus area on each side. Consequently, extend and retract forces are perfectly balanced at 15079 N at 0.5 MPa (up to 27141 N at 0.9 MPa). The integrated -S magnet enables position tracking via CMSE reed and DMSE electronic sensors housed in the dual side grooves.
Because the rod protrudes from the rear cover, you can mount a secondary cam, position flag, or external guide on the opposite end to drive a secondary mechanism. This through-rod architecture inherently resists torsional rotation better than a single-rod actuator. Fluid supply enters via PT tapered G3/4 ports, and adjustable air cushions at both ends absorb kinetic energy over the 350 mm stroke.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
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 SAID200X350S Is Used
Symmetric Press Drive
Drives a heavy press mechanism where equal force during extension and retraction prevents misalignment and ensures consistent forming pressure.
Twin-Station Transfer
Uses the through-rod design to actuate two separate workstations simultaneously from a single cylinder, maintaining perfect synchronization.
Anti-Rotation Guide
Leverages the dual-rod geometry to prevent torsional deflection when moving heavy industrial molds along a horizontal axis.
Is the Airtac SAID200 Double Rod Cylinder SAID200X350S the Right Cylinder?
Select this 200 mm bore actuator when an application demands immense push and pull symmetry that a single-rod SAI cannot provide. If your force requirement is lower, stepping down to a 160 mm bore yields 9425 N both ways at 0.5 MPa. Conversely, if you need less stroke but similar stability, evaluate smaller bores. The SAID mounting set is restricted to Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting the FB, CA, CB, and CR brackets used on single-rod variants.
With a 350 mm stroke, the extended rod length demands careful attention to side-load and rod-bearing bending; always support the load with an external guide rail to prevent premature wear. Remember that the adjustable air cushions only decelerate the piston near stroke end and do not lock the load. If your machinery must hold a vertical or suspended load without constant air pressure, integrate an external rod lock or specify a SAIL or BSAID clamp-lock cylinder instead.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAID200X350S FAQ
Because the rod exits both ends, the effective piston area is identical in both directions. It generates 15079 N of force both extending and retracting at 0.5 MPa, and 27141 N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552 and serves as a direct replacement for other ISO 15552 double-rod profile cylinders, utilizing PT G3/4 ports and a standard mounting interface.
