About the Airtac SAID100 Double Rod Cylinder SAID100BX55
The AirTAC SAID100X55 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100 mm bore and 55 mm stroke. Because a SUS304 stainless steel rod exits both end covers, the effective annulus area is identical on extend and retract. This yields perfectly symmetric dynamics, providing 3681 N of force each way at 0.5 MPa.
Having a rod protrude from the rear cover allows engineers to mount a position flag or cam on the opposite end to trigger a secondary mechanism. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE solid-state switches, though this specific unit is not equipped with a magnet.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX55 Is Used
Symmetric Transfer
Drives a workpiece back and forth with exactly 3681 N of force in both directions at 0.5 MPa, ensuring perfectly balanced transfer cycles.
Twin-Station Actuation
Uses the front rod to push a primary tool while the rear SUS304 rod simultaneously drives a secondary mechanism or position flag.
Anti-Rotation Slides
Keeps heavy sliding loads guided against rotation better than a single rod, preventing binding in precision vertical slides.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX55 the Right Cylinder?
Choose this 100 mm bore when an application demands equal push and pull forces alongside high anti-rotation stability, which is superior to a single-rod SAI cylinder. If your project requires less force, the 80 mm bore variant offers 2268 N both ways at 0.5 MPa, whereas stepping up is unnecessary for symmetric loads under 3681 N. This model uses a PT G1/2 port and supports mounting accessories Basic, FA, LB, TC, FTC, TCM1, and TCM2.
It is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other standard profile cylinders. Remember that a plain SAID does not hold its load when air is exhausted or a valve is centered; the piston will drift. For dead-end holding, consider a SAIL lock or BSAID clamp-lock cylinder. Since the stroke is under 300 mm, side-load stress on the rod bearing is minimal, but always verify rod alignment.
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 SAID100BX55 FAQ
Because the double-rod design subtracts the rod area from both sides, extend and retract forces are equal. It delivers 3681 N both ways at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa.
Yes, the SAID100X55 is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 double-rod cylinders.
