About the Airtac SAID80 Double Rod Cylinder SAID80BX240
The AirTAC SAID80X240 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80 mm bore and 240 mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force and speed in both directions. This through-rod design generates 2268 N each way at 0.5 MPa and 3175 N at 0.7 MPa.
This variant uses SUS304 stainless steel rods for superior corrosion resistance and includes PT (tapered) G3/8 ports. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting. Note that the rear protruding rod requires additional clearance compared to a single-rod SAI, allowing you to mount a secondary cam or position flag on the opposite end.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX240 Is Used
Symmetric Force Transfer
Drives a workpiece from one side while using the opposing rod end for equal push-pull force, ensuring stable motion without speed variation.
Anti-Rotation Slides
The twin-rod design naturally resists torsional loads, keeping guided slides perfectly aligned without external linear bearings.
Dual-Station Actuation
Mount a secondary tool or position flag on the rear rod to trigger external sensors or drive a secondary mechanism simultaneously.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX240 the Right Cylinder?
Choose this 80 mm bore when an application requires symmetric force and dual-side guidance, generating 2268 N both ways at 0.5 MPa. If you need less force, the 63 mm neighbor provides 1402 N; for heavier drives, the 100 mm bore offers 3681 N. A double-rod configuration is preferred over a single-rod SAI when you need to prevent rotation or actuate twin mechanisms simultaneously.
At 240 mm stroke, the SAID80X240 is within standard limits but requires attention to side-load and rod-bearing bending. For unsupported loads over 300 mm, adding an external guide rail is recommended to prevent premature wear. Remember that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If position holding without live pressure is required, consider the SAIL or BSAID clamp-lock series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAID80BX240 FAQ
Because the double-rod design subtracts the rod area on both sides, the extend and retract forces are equal. The SAID80X240 outputs 2268 N both ways at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, the SAID80X240 is dimensionally interchangeable per ISO 15552 mounting interfaces. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets found on single-rod variants.
