About the Airtac SAID100 Double Rod Cylinder SAID100X155S
The AirTAC SAID100X155-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and a 155mm stroke. Because a rod extends from both end covers, the annulus area is identical on both sides, yielding equal push and pull forces of 3681N at 0.5MPa. This through-rod geometry provides superior anti-rotation guidance and allows a rear cam or position flag to be mounted opposite the primary workpiece.
This specific configuration includes a magnetic piston (-S) for use with AirTAC CMSE reed and DMSE electronic solid-state sensors. It features a robust carbon steel rod, PT tapered port threads, and adjustable air cushioning at both ends. The 155mm stroke is a non-standard made-to-order length, and the extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.

Where the Airtac SAID100 Double Rod Cylinder SAID100X155S Is Used
Symmetric-Force Transfer
Drives a workpiece forward and retracts it with identical 3681N force, ensuring consistent clamping or pushing dynamics in both travel directions.
Rear-End Position Sensing
Uses the protruding rear rod to trigger an external mechanical limit flag while the primary front rod executes the main work cycle.
Anti-Rotation Slides
Leverages the twin-rod structure to guide vertical lifting slides or heavy tooling platforms, preventing torsional twist without external guides.
Is the Airtac SAID100 Double Rod Cylinder SAID100X155S the Right Cylinder?
Select this 100mm bore double-rod cylinder when an application demands symmetric force (3681N each way at 0.5MPa) and dual-side actuation. If you need less force, stepping down to the 80mm bore yields 2268N both ways, whereas moving up to the 125mm bore provides 5734N. The twin-rod design is chosen over a single-rod SAI when the mechanism requires rear-rod sensing, a secondary tool mount, or enhanced load stability against rotation.
As a double-acting pneumatic cylinder, this model does not hold its position if air pressure is lost; use a SAIL lock, BSAID clamp-lock, or external pilot-operated check valve for load-holding. It is dimensionally interchangeable per ISO 15552, utilizing a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and a G1/2 port. Because the stroke is 155mm, ensure adequate rear-rod clearance and consider an external guide for any heavy offset loads.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAID100X155S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. It generates 3681N in both directions at 0.5MPa, 5153N at 0.7MPa, and 6626N at 0.9MPa.
Yes, it is dimensionally interchangeable per ISO 15552. It shares the same mounting footprint and utilizes the standard SAID accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting single-rod only mounts like FB or CA.
