About the Airtac SAID50 Double Rod Cylinder SAID50AX160
The AirTAC SAID50X160 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 160mm stroke. Because a rod extends from both end covers, the annulus area is identical on both sides, yielding exactly 825N of force in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This variant is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and a PT tapered port thread. The rear rod end can drive a secondary mechanism or mount a position flag, while the twin rods provide superior anti-rotation guidance compared to a single-rod SAI cylinder.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX160 Is Used
Symmetric Force Transfer
Ideal for pressing or transferring parts where the extend and retract strokes must deliver identical 825N force and speed without requiring pressure adjustments.
Anti-Rotation Slides
The twin-rod design prevents piston rotation, providing precise linear guidance for vertical lifting slides or guided workpiece handling.
Rear-Rod Actuation
Mount the primary workpiece on the front rod and use the rear rod end to drive a secondary mechanism or mount a physical position limit flag.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX160 the Right Cylinder?
Choose this 50mm bore when an application requires perfectly symmetric force and speed, as the twin rods ensure equal 825N output both ways at 0.5 MPa. If your mechanism needs less force, step down to the 40mm bore (528N both ways); if you need more push or pull power, step up to the 63mm bore (1402N both ways). The double-rod design is specifically selected over a single-rod SAI when dual-side guidance, anti-rotation control, or rear-rod actuation is required.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. To match this exact configuration, specify the 50mm bore, 160mm stroke, PT port thread, SUS420J2 rod material, and no magnet. Note that a plain SAID does not hold its position if air pressure is lost; for load-holding requirements, consider the SAIL or BSAID series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAID50 Double Rod Cylinder SAID50AX160 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It delivers an equal force of 825N in both extend and retract directions at 0.5 MPa (1154N at 0.7 MPa).
Yes, the SAID50X160 is a profile cylinder dimensionally interchangeable per ISO 15552. It supports a specific mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR.
