About the Airtac SAID100 Double Rod Cylinder SAID100X350S
The AirTAC SAID100X350-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 350mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding exactly 3681 N of force on both extend and retract at 0.5 MPa. The integrated magnet (-S) pairs directly with AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves.
A rod protrudes from both end covers, allowing you to mount the primary workpiece on the front and a position flag or secondary cam on the rear. This through-rod architecture provides superior anti-rotation guidance compared to a single-rod SAI. The standard carbon steel rods feature M20x1.5 threads, and the unit uses PT tapered ports sized at G1/2.

Where the Airtac SAID100 Double Rod Cylinder SAID100X350S Is Used
Symmetric Force Transfer
Drives a dual-sided lifting mechanism where the equal 3681 N extend and retract forces at 0.5 MPa prevent jerky movements and ensure smooth, balanced load shifting.
Through-Rod Sensing
Mounts the primary tool on the front rod while the rear rod carries a DMSE electronic sensor flag, allowing external position verification without interfering with the main work area.
Anti-Rotation Slides
Utilizes the twin-rod architecture to guide a heavy machining fixture, resisting torsional twist and maintaining precise alignment during clamping operations.
Is the Airtac SAID100 Double Rod Cylinder SAID100X350S the Right Cylinder?
Select this 100mm bore when an application demands symmetric thrust that a single-rod cylinder cannot provide. If you need less force, stepping down to the 80mm bore drops the both-way output to 2268 N at 0.5 MPa; stepping up to 125mm increases it to 5734 N. The double-rod design is chosen specifically for twin-station actuation or when rear-rod sensing is required. Remember that the adjustable air cushions only decelerate the piston near stroke end; they do not hold the load. If air pressure is lost, the piston will drift, requiring an external rod lock or a BSAID clamp-lock cylinder for secure positioning.
At 350mm of stroke, the unsupported rod length increases susceptibility to bending under side loads. Using an external guide rail is highly recommended to prevent premature rod-bearing wear. For ISO 15552 drop-in replacements, match the 100mm bore, 350mm stroke, G1/2 PT ports, and mounting accessories from the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2), noting that FB, CA, CB, and CR mounts are excluded from this double-rod variant.

- ✓ 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 SAID100 Double Rod Cylinder SAID100X350S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It generates 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa on both extend and retract strokes.
Yes, the SAID100X350-S is dimensionally interchangeable per ISO 15552. You can drop it in place of other standard profile double-rod cylinders by matching the 100mm bore, 350mm stroke, and G1/2 ports, using the available Basic, FA, LB, or TC mounting interfaces.
