About the Airtac SAID80 Double Rod Cylinder SAID80AX550
The AirTAC SAID80X550 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80 mm bore and 550 mm stroke. Because the piston rod extends from both end covers, the annulus area is identical on both sides, yielding exactly 2268 N of force in both extend and retract directions at 0.5 MPa. This symmetric output is ideal for mechanisms requiring perfectly balanced push and pull dynamics.
This configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of position switches. Note that the rear rod protrudes during operation, requiring additional clearance behind the cylinder.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX550 Is Used
Symmetric Transfer
Drives a transfer carriage with equal push and pull velocity, ensuring precise timing without requiring flow controls to balance directional speed differences.
Anti-Rotation Slide
The twin-rod geometry prevents mechanical twisting during heavy horizontal indexing, keeping the workpiece perfectly aligned without external linear bearings.
Rear-Cam Actuation
The protruding rear rod end drives a secondary mechanical cam or limit flag, allowing one pneumatic cycle to trigger downstream machine logic simultaneously.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX550 the Right Cylinder?
Select this 80 mm bore when an application demands matched bidirectional force and superior anti-rotation guidance that a single-rod SAI cannot provide. Stepping down to a 63 mm bore drops the both-way force to 1402 N, while this SAID80X550 provides a robust 2268 N at 0.5 MPa. It uses a PT G3/8 port and supports the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
At 550 mm of stroke, the 25 mm rod is highly susceptible to side-load bending; an external guide rail is strongly recommended to prevent premature rod-bearing wear. As a standard double-acting cylinder, it does not hold position if air pressure is lost—use a BSAID clamp-lock or external pilot-operated check valve for load-holding. It is dimensionally interchangeable per ISO 15552 for direct drop-in replacement.
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 SAID80AX550 FAQ
Because it is a double-rod cylinder, the effective piston area is identical in both directions. It provides 2268 N of force both extending and retracting at 0.5 MPa, and 3175 N at 0.7 MPa.
Yes, the SAID80X550 is dimensionally interchangeable per ISO 15552 mounting dimensions. It shares the exact footprint of other ISO 15552 double-rod profile cylinders, allowing a direct drop-in replacement.
