About the Airtac SAID80 Double Rod Cylinder SAID80BX220
The AirTAC SAID80X220 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 220mm stroke. A single piston drives a rod out of both end covers, meaning the annulus area is identical on extend and retract. Consequently, it generates exactly 2268N of force in both directions at 0.5 MPa, ensuring perfectly symmetric speed and thrust for demanding transfer tasks.
This specific configuration features SUS304 stainless steel rods (material code B) for superior corrosion resistance in washdown or chemically active settings. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Because the rear rod protrudes past the back cover, you must account for additional clearance when designing your machine envelope.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX220 Is Used
Symmetric Force Transfer
Pushes and pulls heavy jigs with equal 2268N thrust at 0.5 MPa, ensuring balanced momentum without asymmetric acceleration spikes.
Anti-Rotation Slides
Twin SUS304 rods guide the payload against torsional twist, maintaining precise linear tracking on long-stroke handling systems.
Dual-Station Actuation
Mounts the primary tool on the front rod end and a secondary cam or position flag on the rear protrusion to drive two mechanisms simultaneously.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX220 the Right Cylinder?
Select this 80mm bore when an application requires substantial bidirectional force (2268N at 0.5 MPa, up to 4082N at 0.9 MPa) that a smaller 63mm bore (1402N at 0.5 MPa) cannot provide, but without jumping to the bulkier 100mm size. The twin-rod architecture is chosen over a single-rod SAI when the mechanism demands dual-side guidance to prevent rotation, or when a rear cam and position flag must be driven simultaneously with the primary workpiece. It uses PT tapered ports sized at G3/8.
With a 220mm stroke, the extended rod length requires careful attention to side-load and rod-bearing bending. For optimal performance and longevity, utilize an external guide rail to support the load and prevent cantilever stresses. Remember that a plain SAID relies on air pressure to maintain position; it will drift if air is lost or the valve is centered. If the load must be held mechanically during an air failure, consider the BSAID clamp-lock variant or an external rod lock. This model is dimensionally interchangeable per ISO 15552 and supports mountings 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 SAID80BX220 FAQ
Because the rod occupies both sides of the piston, the effective area is equal in both directions. The SAID80X220 delivers 2268N of force at 0.5 MPa, 3175N at 0.7 MPa, and 4082N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID80X220 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.
