About the Airtac SAID80 Double Rod Cylinder SAID80X185S
The AirTAC SAID80X185-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 185mm stroke. Because a rod extends from both end covers, the annulus area is identical on both sides, yielding exactly 2268 N of force in both extend and retract directions at 0.5 MPa. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic solid-state switches fitted into the dual-side sensor grooves.
This through-rod design is ideal for applications needing rear-side actuation, allowing you to mount a primary workpiece on one end and a cam, limit flag, or secondary mechanism on the opposite end. The extruded aluminum barrel provides a rigid, lightweight structure, while the standard carbon steel rod handles high side loads. It features adjustable air cushions at both ends to decelerate the piston near stroke limits.

Where the Airtac SAID80 Double Rod Cylinder SAID80X185S Is Used
Symmetric Force Transfer
Drives a workpiece back and forth with equal 2268 N force on both strokes, ensuring consistent performance in pushing and pulling operations.
Anti-Rotation Slides
The twin-rod design prevents piston rotation, providing precise linear guidance for lifting and pressing slides without external guide rods.
Dual-Side Actuation
Mount a primary tool on the front rod and a secondary cam or position flag on the rear rod to trigger external reed or electronic sensors.
Is the Airtac SAID80 Double Rod Cylinder SAID80X185S the Right Cylinder?
Select this 80mm bore when your application requires balanced, high-force transfer in both directions, stepping up from a 63mm bore (which provides 1402 N at 0.5 MPa) to handle heavier symmetric loads. A double-rod configuration is chosen over a single-rod SAI when twin-station actuation, dual-side guidance, or anti-rotation stability is required. For this specific 185mm stroke, the 25mm rod diameter and M20x1.5 thread offer robust load support, but always verify the rod bearing capacity if the load is cantilevered.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 double-rod cylinders. Ensure your setup matches the PT G3/8 port thread and uses compatible mounting accessories from the SAID set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Note that a plain SAID does not hold its load if air pressure is lost; for fail-safe holding, consider an external rod lock or the BSAID clamp-lock variant.
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 SAID80X185S FAQ
Because the double-rod design subtracts the rod area from both sides, the force is equal in both directions. It provides 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, the SAID80X185-S is built to ISO 15552 mounting interface dimensions, making it a drop-in replacement for other ISO 15552 profile double-rod cylinders, provided your porting matches the PT G3/8 thread.
