About the Airtac SAID80 Double Rod Cylinder SAID80X35
The AirTAC SAID80X35 is a double-acting, double-rod ISO 15552 profile cylinder engineered to deliver matched extend and retract forces. Because a carbon steel piston rod exits both end covers, the effective annulus area is identical on each side, yielding a consistent 2268 N of thrust in either direction at 0.5 MPa. This symmetric output is ideal for mechanisms requiring balanced kinetic profiles.
Beyond equal force, the through-rod design allows you to mount a primary workpiece on the front thread and a secondary cam, position flag, or external guide on the rear. The extruded aluminum barrel features dual sensor grooves, accommodating CMSE reed or DMSE electronic switches if a magnet is specified later. Adjustable air cushions at both ends absorb end-of-stroke impact.

Where the Airtac SAID80 Double Rod Cylinder SAID80X35 Is Used
Symmetric Force Transfer
Drives horizontal transfer arms where identical push and pull momentum is critical for maintaining precise product spacing.
Anti-Rotation Slides
Guides heavy vertical lifting slides with high torsional resistance, preventing load deflection during rapid 30-800 mm/s cycles.
Dual-Station Actuation
Actuates a primary clamping tool on the front rod while using the rear protrusion to trigger a remote position flag.
Is the Airtac SAID80 Double Rod Cylinder SAID80X35 the Right Cylinder?
Selecting this 80 mm bore over the neighboring 63 mm variant increases your bidirectional force from 1402 N to 2268 N at 0.5 MPa, while stepping up to a 100 mm bore provides 3681 N. The twin-rod architecture is specifically chosen when an application demands high resistance to torsion or requires actuating a secondary mechanism from the rear rod end. Unlike a single-rod SAI, the SAID80X35 ensures speed and push/pull forces remain perfectly symmetrical.
This cylinder uses PT tapered ports (G3/8) and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It is dimensionally interchangeable per ISO 15552 standards. Note that the adjustable air cushions decelerate the piston but do not lock the load; if position holding without live air pressure is required, consider a BSAID clamp-lock cylinder or an external pilot-operated check valve.
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 SAID80X35 FAQ
The SAID80X35 provides equal force in both extend and retract directions due to its double-rod design. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, the SAID80X35 is a profile cylinder dimensionally interchangeable with other ISO 15552 double-rod cylinders. It shares standard mounting dimensions but uses a reduced accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and requires rear-rod clearance.
