About the Airtac SAID100 Double Rod Cylinder SAID100BX220S
The AirTAC SAID100X220-S is a double-acting, double-rod ISO 15552 profile cylinder. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 3681 N of force each way at 0.5 MPa. This twin-rod architecture provides superior anti-rotation guidance and lets you mount a primary workpiece on the front while tracking position with a rear cam or flag.
Equipped with a SUS304 stainless steel rod and a PT tapered port thread, this 100mm bore unit operates at 30-800 mm/s. The integrated magnet works seamlessly with AirTAC CMSE reed and DMSE solid-state sensors in the dual-side barrel grooves. It functions as a drop-in replacement for any ISO 15552 double-rod cylinder.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX220S Is Used
Symmetric Transfer
Drives a dual-sided transfer carriage where equal push and pull force (3681 N at 0.5 MPa) ensures smooth, balanced motion without asymmetric acceleration.
Anti-Rotation Slides
Uses the twin-rod geometry to guide heavy machining slides, preventing piston rotation and maintaining strict tool alignment during clamping.
Rear-Side Sensing
Mounts the primary actuator on the front rod while using the rear rod end to trip a DMSE solid-state sensor for precise end-of-stroke confirmation.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX220S the Right Cylinder?
Choose this 100mm bore when an application requires balanced bidirectional force and high stability. If you need less push, step down to the 80mm bore (2268 N at 0.5 MPa); if you need more, move up to the 125mm bore (5734 N at 0.5 MPa). The double-rod design is selected over a single-rod SAI when a secondary mechanism or rear-side sensing is required. Remember that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If position holding without live air pressure is needed, use an external pilot-operated check valve or explore the BSAID clamp-lock series.
At a 220mm stroke, the 25mm rod and M20x1.5 thread handle substantial side loads, but you should still use an external guide for heavy off-center loads. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (FB, CA, CB, and CR are single-rod SAI only).
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 SAID100BX220S FAQ
Because the double-rod design subtracts the rod area from both sides, the extend and retract forces are equal. It outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa in both directions.
Yes, the SAID100X220-S is dimensionally interchangeable per ISO 15552. It shares the exact mounting interface and profile barrel dimensions of other standard ISO 15552 double-rod cylinders, allowing a direct drop-in replacement.
