About the Airtac SAI160 Standard Cylinder SAI160AX500S
The AirTAC SAI160X500-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 10053 N push force at 0.5 MPa, this 160 mm bore unit is built to execute demanding linear motion tasks. The 500 mm stroke provides extensive travel for large-scale material handling. A standout feature of this specific configuration is the SUS420J2 stainless steel piston rod (material code A), which offers superior corrosion resistance compared to standard carbon steel, making it ideal for humid or chemically active factory settings.
Furthermore, this model includes a built-in magnet (-S) for position sensing. The extruded aluminum barrel features sensor grooves on both sides, allowing for the seamless installation of CMSE or DMSE reed switches. Fluid ports utilize PT tapered threading, and the cylinder incorporates adjustable air cushions at both ends to manage the significant kinetic energy generated by its 318 kgf maximum theoretical force class.

Where the Airtac SAI160 Standard Cylinder SAI160AX500S Is Used
Heavy Stamp Pressing
Generates 14074 N of thrust at 0.7 MPa to drive large metal forming and heavy stamping operations securely.
Large Component Ejection
The 500 mm stroke provides the long reach needed to push bulky automotive molds or cast parts safely out of machining centers.
Pallet Handling
Lifts and positions heavy loaded pallets on automated conveyor lines, utilizing the SUS420J2 rod for moisture resistance.
Is the Airtac SAI160 Standard Cylinder SAI160AX500S the Right Cylinder?
Selecting the SAI160X500-S means stepping into a high-force tier, bridging the gap between the 125 mm bore (6136 N at 0.5 MPa) and the massive 200 mm bore (15708 N at 0.5 MPa). For applications requiring slightly less thrust, the 125 mm option saves space, but this 160 mm unit is necessary when pushing or lifting loads exceeding one ton. Because this is a 500 mm stroke, the extended unsupported rod is highly susceptible to bending under side loads. To prevent premature seal failure and rod bearing deformation, always pair this cylinder with an external guide rail or use a dedicated guided cylinder assembly.
As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable direct replacement for other ISO 15552 cylinders, matching standard mounting interfaces like the TC trunnion or LB foot brackets. Note that the standard SAI does not hold its position when air pressure is lost; the piston will drift. For gravity-loaded vertical applications requiring fail-safe holding without live pressure, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead of relying on the air cushion.
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.
