About the Airtac SAID100 Double Rod Cylinder SAID100BX70
The AirTAC SAID100X70 is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetric actuation. Because the piston rod extends from both end covers, the annulus area is identical on both sides, yielding an equal extend and retract force of 3681 N at 0.5 MPa. This through-rod geometry provides superior anti-rotation guidance and allows a rear-mounted position flag to trigger external limits.
This specific configuration features SUS304 stainless steel rods (option B) for superior corrosion resistance, PT tapered port threads, and adjustable air cushioning at both ends. The extruded aluminum barrel includes dual sensor grooves, allowing you to mount CMSE reed or DMSE electronic switches on either side without extra brackets.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX70 Is Used
Symmetric Force Transfer
Drives heavy workpieces back and forth with identical 3681 N thrust in both directions, ensuring consistent clamping and pushing without speed discrepancies.
Anti-Rotation Slides
The dual SUS304 rods guide the load against twisting forces far better than a single rod, maintaining precise alignment for heavy tooling platforms.
Rear-End Sensing
Uses the protruding rear rod end to physically trip an external limit switch or carry a magnet for DMSE electronic sensors, freeing the front rod for primary work.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX70 the Right Cylinder?
Select this 100 mm bore when an application demands substantial equal-force transfer in both directions, generating 3681 N each way at 0.5 MPa. If your mechanism requires less force, stepping down to the 80 mm bore drops the bidirectional output to 2268 N, whereas upgrading to the 125 mm bore increases it to 5734 N. The twin-rod design is chosen over a single-rod SAI when you need to drive a load on one end while mounting a cam or sensor flag on the opposite end.
This cylinder uses PT tapered ports and supports a reduced ISO 15552 mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets found on single-rod variants. Note 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 pilot-operated check valve or a BSAID clamp-lock cylinder for true position holding.
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 SAID100BX70 FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It provides an equal force of 3681 N in both extend and retract directions at 0.5 MPa, and 5153 N at 0.7 MPa.
Yes, the SAID100X70 is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 double-rod profile cylinders, matching the standard 100 mm bore and mounting dimensions.
