About the Airtac SAID50 Double Rod Cylinder SAID50X80S
The AirTAC SAID50X80-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 80mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding equal bidirectional force of 825N at 0.5 MPa. The integrated -S magnet pairs seamlessly with CMSE reed and DMSE electronic switches via sensor grooves machined into both sides of the extruded aluminum barrel.
This through-rod architecture allows mounting the primary workpiece on one end and a secondary cam, position flag, or guidance mechanism on the rear rod. It provides superior anti-rotation stability compared to a single-rod SAI. Adjustable air cushions at both ends decelerate the piston near stroke end, but note this cylinder drifts if air pressure is lost and does not inherently hold a load.

Where the Airtac SAID50 Double Rod Cylinder SAID50X80S Is Used
Symmetric Force Transfer
Ideal for shuttle systems requiring identical 825N push and pull forces to move payloads equally in both directions without speed variations.
Anti-Rotation Slides
The twin carbon steel rods prevent piston twisting under offset loads, ensuring precise linear guidance for vertical lifting slides.
Through-Rod Sensing
Mount the primary tool on the front rod and a CMSE/DMSE position flag on the rear protruding rod to track stroke limits externally.
Is the Airtac SAID50 Double Rod Cylinder SAID50X80S the Right Cylinder?
Select this 50mm bore model when an application demands symmetric push and pull forces, stepping up from the 40mm bore (528N at 0.5 MPa) for heavier twin-station actuation. Stepping up further to the 63mm bore provides 1402N if higher thrust is required. The double-rod design is chosen over a single-rod SAI when dual-side guidance or rear-rod sensing is strictly needed. As a true ISO 15552 cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a reduced mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR. For load-holding without live pressure, consider an external rod lock or the BSAID clamp-lock variant.

- ✓ 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 SAID50X80S FAQ
The double-rod design provides equal force in both directions. It delivers 825N at 0.5 MPa, 1154N at 0.7 MPa, and 1484N at 0.9 MPa for both extend and retract strokes.
Yes, it is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 double-rod cylinders, utilizing a PT G1/4 port and standard mounting interfaces.
