About the Airtac SAID160 Double Rod Cylinder SAID160AX85
The AirTAC SAID160X85 is a double-acting, double-rod ISO 15552 profile cylinder. A single piston drives a rod out of both end covers, yielding equal extend and retract forces. It generates 9425 N of thrust each way at 0.5 MPa, scaling to 13194 N at 0.7 MPa. Because the annulus area is identical on both sides, push and pull power are perfectly matched.
This unit features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and surface hardness. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Fluid supply is controlled via PT G3/4 tapered ports, and the piston travels an 85 mm stroke with adjustable air cushioning at both ends to dampen impact.

Where the Airtac SAID160 Double Rod Cylinder SAID160AX85 Is Used
Anti-Rotation Slides
Uses the twin-rod structure to guide heavy machinery slides, preventing piston rotation and ensuring precise linear movement under heavy loads.
Symmetric Force Transfer
Ideal for pressing and forming stations that require identical push and pull forces, leveraging the equal annulus area to deliver 9425 N both ways.
Rear-Tool Actuation
Mounts a secondary tool or position flag on the rear rod end to drive a secondary mechanism or trigger sensors without needing extra clearance.
Is the Airtac SAID160 Double Rod Cylinder SAID160AX85 the Right Cylinder?
Choose this 160 mm bore when an application demands symmetric force and high thrust, offering 9425 N in both directions at 0.5 MPa. If your mechanism requires less power, stepping down to the 125 mm bore provides 5734 N both ways. The twin-rod design is selected over a single-rod SAI when the mechanism needs dual-side guidance to prevent rotation, or when a rear-position flag must trigger a limit switch. Note that this cylinder does not hold its load when air pressure is lost; if position holding is required without live pressure, consider the BSAID clamp-lock variant.
This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders. It uses a reduced mounting accessory set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets found on single-rod versions. The 40 mm rod diameter and M36x2 thread provide high structural rigidity. Since the stroke is 85 mm, side-load stress on the rod bearing is minimal, but external guides are always 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 SAID160 Double Rod Cylinder SAID160AX85 FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. It delivers 9425 N of force in both extend and retract directions at 0.5 MPa, and 13194 N at 0.7 MPa.
Yes, the SAID160X85 is a profile cylinder with standard ISO 15552 mounting dimensions, making it interchangeable with other ISO 15552 double-rod cylinders. It uses PT G3/4 ports and a M36x2 rod thread.
