About the Airtac SAID80 Double Rod Cylinder SAID80X35S
The AirTAC SAID80X35-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 35mm stroke and an integrated magnet. Because a carbon steel rod exits both end covers, the effective piston area is identical on extend and retract. This yields equal force and speed in both directions, generating 2268N each way at 0.5MPa and 3175N at 0.7MPa.
The twin-rod architecture allows you to mount the primary workpiece on the front rod end and a position flag or cam on the rear. Machined for PT tapered ports (G3/8), the extruded aluminum barrel includes sensor grooves on both sides. The -S magnet enables precise tracking using AirTAC CMSE reed or DMSE electronic solid-state switches.

Where the Airtac SAID80 Double Rod Cylinder SAID80X35S Is Used
Symmetric Transfer
Drives a workpiece forward and retracts it with identical 2268N force, ensuring perfectly balanced speed and thrust for stable component shifting.
Anti-Rotation Slides
Uses the dual carbon steel rods to guide heavy vertical loads without twisting, eliminating the need for external linear guide rails in compact spaces.
Rear-End Sensing
Mounts the primary tool on the front rod and a position flag on the rear protruding rod, using DMSE sensors to confirm stroke completion from the back side.
Is the Airtac SAID80 Double Rod Cylinder SAID80X35S the Right Cylinder?
Select this 80mm bore when an application requires symmetric thrust that a single-rod SAI cannot provide, or step down to a 63mm bore (1402N at 0.5MPa) if the 2268N output exceeds your load requirements. The double-rod design inherently resists rotation and supports twin-station actuation. For dimensionally interchangeable drop-in replacements per ISO 15552, match the 80mm bore, 35mm stroke, PT G3/8 port, and mounting accessories from the SAID set: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (FB, CA, CB, and CR are excluded).
Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not lock the load. If air pressure is lost, the cylinder will drift, requiring an external rod lock or a BSAID clamp-lock cylinder for secure 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 SAID80 Double Rod Cylinder SAID80X35S FAQ
Because the double-rod design has the same annulus area on both sides, it provides equal force in both directions: 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa.
Yes, the SAID80X35-S is dimensionally interchangeable with other ISO 15552 profile cylinders. Match the 80mm bore, 35mm stroke, and PT G3/8 port size for a drop-in replacement.
