About the Airtac SAID80 Double Rod Cylinder SAID80X210S
The AirTAC SAID80X210-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 210 mm stroke and an 80 mm bore. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding equal bidirectional force of 2268 N at 0.5 MPa and 3175 N at 0.7 MPa. The integrated -S magnet enables position sensing using AirTAC CMSE reed or DMSE electronic switches seated in the dual-side barrel grooves.
This through-rod design is built for dual-side guidance and anti-rotation, allowing you to mount a workpiece on one end and a cam or position flag on the rear. It features adjustable air cushions at both ends (36 mm travel) to decelerate the piston smoothly, and PT tapered port threads (G3/8) for reliable pneumatic sealing.

Where the Airtac SAID80 Double Rod Cylinder SAID80X210S Is Used
Symmetric Force Transfer
Drives mechanisms where equal push and pull forces are critical, ensuring consistent performance in both directions without force drop on the return stroke.
Anti-Rotation Slides
Utilizes the twin through-rods to guide loads and prevent rotation, maintaining strict parallelism for precision sliding fixtures.
Dual-Side Tooling Actuation
Mounts a primary work tool on the front rod and a secondary cam or position flag on the rear rod to operate separate mechanisms simultaneously.
Is the Airtac SAID80 Double Rod Cylinder SAID80X210S the Right Cylinder?
Choose this 80 mm bore when an application requires symmetric push and pull forces alongside high anti-rotation stability that a single-rod SAI cannot provide. If your project demands less force, the 63 mm bore offers 1402 N each way at 0.5 MPa; for heavier loads, stepping up to the 100 mm bore provides 3681 N in both directions. The SAID80X210-S is dimensionally interchangeable per ISO 15552, requiring a drop-in replacement with the same 80 mm bore, 210 mm stroke, G3/8 PT port, and matching mounting accessory.
For strokes of 300 mm or longer, the unsupported rod load increases bending stress on the rod bearing; an external guide is recommended to prevent premature wear. Note that a plain SAID does not hold its load when air is exhausted or a valve is centered—the piston drifts. For position holding without live pressure, consider an external rod lock or the related SAIL or BSAID clamp-lock models. Available mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAID80X210S FAQ
The SAID80X210-S provides equal force in both extend and retract directions due to its double-rod design. It delivers 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
It features an ISO 15552 mounting interface, making it a drop-in replacement for other ISO 15552 profile cylinders. The included -S magnet works directly with AirTAC CMSE reed and DMSE electronic sensors in the dual barrel grooves.
