About the Airtac SAID80 Double Rod Cylinder SAID80X50S
The AirTAC SAID80X50-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 50mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force and speed in both directions at 2268 N each way at 0.5 MPa.
This through-rod design allows mounting the primary workpiece on one end while attaching a cam or position flag to the rear rod for dual-side sensing. Equipped with a magnet (-S), it integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors fitted into the dual side grooves of the extruded aluminum barrel.

Where the Airtac SAID80 Double Rod Cylinder SAID80X50S Is Used
Symmetric Force Transfer
Drives push-and-pull mechanisms where equal 2268 N force and speed in both directions are critical for balanced machine timing.
Dual-Side Actuation
Mounts a primary tool on the front rod and a secondary cam or drive on the rear rod to operate two separate mechanisms simultaneously.
Anti-Rotation Slides
The twin-rod configuration guides the load against rotation, preventing unwanted twisting during vertical or horizontal movements.
Is the Airtac SAID80 Double Rod Cylinder SAID80X50S the Right Cylinder?
Select this 80mm bore when an application requires symmetric force and anti-rotation guidance that a single-rod SAI cannot provide. If your project needs less force, the 63mm bore offers 1402 N both ways at 0.5 MPa; if you need more power, the 100mm bore provides 3681 N. The SAID80X50-S uses a G3/8 PT port and supports mountings Basic, FA, LB, TC, FTC, TCM1, and TCM2.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other standard double-rod profiles. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If position holding is required when air is exhausted, use an external rod lock or a BSAID clamp-lock cylinder.
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 SAID80X50S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the extend and retract forces are equal. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa in both directions.
Yes, the SAID80X50-S is an extruded aluminum profile cylinder with an ISO 15552 mounting interface, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
