About the Airtac SAID80 Double Rod Cylinder SAID80BX155S
The AirTAC SAID80X155-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 155mm stroke and an integrated magnet. Because the piston rod extends from both end covers, the effective annulus area is identical on both sides, yielding an equal extend and retract force of 2268N at 0.5MPa. This symmetric output is ideal for mechanisms requiring consistent power in both travel directions.
This specific configuration utilizes a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. You can mount the primary workpiece on the front rod end while using the rear protrusion to carry a cam, a limit flag, or drive a secondary mechanism. The extruded aluminum barrel features sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic switches.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX155S Is Used
Symmetric Force Transfer
Drives heavy sliding carriages requiring identical push and pull power, utilizing the 2268N both-way output to maintain consistent acceleration and deceleration.
Dual-Station Actuation
Simultaneously operates two separate tooling stations from a single cylinder, using the front and rear rod extensions to perform parallel work.
Anti-Rotation Guidance
Keeps long heavy loads guided and prevented from twisting during vertical or horizontal transfer, leveraging the twin-rod structure for superior stability.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX155S the Right Cylinder?
Select this 80mm bore cylinder when an application demands equal bi-directional force and anti-rotation guidance that a single-rod SAI cannot provide. If your mechanism requires less force, stepping down to the 63mm bore offers 1402N both ways at 0.5MPa; if you need more power, the 100mm bore provides 3681N. This SAID80X155-S is dimensionally interchangeable per ISO 15552 and uses PT tapered ports sized at G3/8.
The adjustable air cushions at both ends decelerate the piston near stroke ends but do not hold the load if air pressure is lost; for position holding without live pressure, consider a SAIL lock cylinder or an external pilot-operated check valve. Mounting options include the SAID subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). As the 155mm stroke is under the 300mm threshold, side-load stress on the rod bearing is moderate, but external guidance is still recommended for heavy radial loads.
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 SAID80BX155S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. It generates 2268N both ways at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa.
Yes, it is dimensionally interchangeable per ISO 15552. It shares the standard mounting interface and profile barrel dimensions, allowing it to serve as a drop-in replacement for other ISO 15552 double-rod cylinders.
