About the Airtac SAID50 Double Rod Cylinder SAID50X70
The AirTAC SAID50X70 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 70mm stroke. Because the piston rod extends from both end covers, the effective annulus area is identical on both sides, yielding an equal extend and retract force of 825N at 0.5 MPa. A single piston carries the load out of both ends, allowing you to mount the primary workpiece on the front rod and a position flag or secondary cam on the rear rod.
This extruded aluminum barrel includes sensor switch grooves on both sides for flexible mounting of CMSE or DMSE switches. It features standard carbon steel rods and PT tapered port threads. The variable air cushion at both ends decelerates the piston near stroke end, though it does not lock the load when air pressure is lost.

Where the Airtac SAID50 Double Rod Cylinder SAID50X70 Is Used
Symmetric Transfer
Drives a shuttle mechanism where identical push and pull forces of 825N ensure consistent acceleration and deceleration of the payload in both directions.
Anti-Rotation Slide
The twin-rod geometry prevents the piston from twisting under offset loads, keeping the guided tooling perfectly aligned during the 70mm travel.
Dual-Station Actuation
Front rod drives the primary clamp while the rear rod mechanically triggers a secondary process or physical limit flag simultaneously.
Is the Airtac SAID50 Double Rod Cylinder SAID50X70 the Right Cylinder?
Select this 50mm bore when an application requires symmetric force and speed in both directions, offering 825N each way at 0.5 MPa. If you need less force, the 40mm bore provides 528N both ways; if you need more, the 63mm bore offers 1402N. The twin-rod design is chosen over a single-rod SAI when dual-side guidance, anti-rotation stability, or rear-rod actuation is required. For drop-in replacements, match the 50mm bore, 70mm stroke, PT port thread, and mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Since this model lacks the -S magnet, it cannot host reed or electronic sensors without modification.
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 SAID50X70 FAQ
The SAID50X70 provides equal force in both extend and retract directions due to its double-rod design. It outputs 825N at 0.5 MPa, 1154N at 0.7 MPa, and 1484N at 0.9 MPa.
Yes, the SAID50X70 is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 double-rod profile cylinders by matching the 50mm bore, 70mm stroke, and mounting dimensions.
