About the Airtac SAID80 Double Rod Cylinder SAID80BX375
The AirTAC SAID80X375 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 375mm stroke. Because a piston rod exits both end covers, the annulus area is identical in both directions. This means the cylinder generates exactly 2268N of thrust and pull at 0.5MPa, ensuring equal force and speed for extend and retract movements.
This specific configuration uses SUS304 stainless steel rods (material code B) for superior corrosion resistance in harsh environments. The extruded aluminum barrel includes sensor grooves on both sides. Note that the rear rod protrudes during operation, so you must allow extra clearance behind the rear cover for the rod and any mounted cam or position flag.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX375 Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where equal 2268N push and pull forces at 0.5MPa are required to move a workpiece smoothly in both directions without speed variation.
Anti-Rotation Slides
The twin SUS304 rods exiting both ends keep the load guided and prevent rotational drift on long 375mm stroke slides, eliminating the need for a separate guide rail.
Dual-Station Actuation
Mount the primary workpiece on the front rod and a mechanical position flag on the rear rod to trigger external mechanical limit switches at separate stations.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX375 the Right Cylinder?
Choose this 80mm bore when you need 2268N of force both ways at 0.5MPa; step down to a 63mm bore for 1402N, or up to a 100mm bore for 3681N. The double-rod design is selected over a single-rod SAI when an application requires dual-side guidance, anti-rotation control, or a rear rod to drive a secondary mechanism. Because this is a 375mm stroke, long unsupported loads can induce side-load bending on the rod bearings; always use an external guide to prevent premature wear.
This model uses PT tapered port threads and lacks a magnet, so it cannot host CMSE or DMSE sensors without modification. It is dimensionally interchangeable per ISO 15552 and uses the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). 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, use an SAIL lock, BSAID clamp-lock, or external rod lock.
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 SAID80BX375 FAQ
Because the double-rod design subtracts the rod area on both sides, the output force is equal in both directions. It provides 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa for both extend and retract strokes.
Yes. It is a profile cylinder dimensionally interchangeable per ISO 15552, but it uses a reduced mounting set. You can use Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories, but FB, CA, CB, and CR mounts are not compatible with this double-rod body.
