About the Airtac SAI160 Standard Cylinder SAI160BX650S
The AirTAC SAI160X650-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning. Delivering a robust 14074 N push force at 0.7 MPa, this 160 mm bore unit is tailored for substantial actuation tasks. The 650 mm stroke provides the extended reach needed for large-scale material handling and forming operations.
Configured with a SUS304 stainless steel rod (option B), this model offers superior corrosion resistance for humid or chemically exposed environments. The integrated -S magnet enables seamless position tracking using CMSE or DMSE sensor switches fitted into the dual-side barrel grooves. It features PT tapered port threads and adjustable air cushions at both ends to manage heavy piston momentum.

Where the Airtac SAI160 Standard Cylinder SAI160BX650S Is Used
Heavy Stamping
Provides the 14074 N force required to drive large metal stamping presses and forming dies over a 650 mm working distance.
Automotive Assembly
Actuates large chassis positioning fixtures and heavy component lifting arms where the SUS304 rod prevents workshop fluid corrosion.
Bulk Material Handling
Shifts heavy pallet loads and redirects substantial bulk material conveyor lines, utilizing the extended stroke for wide transitions.
Is the Airtac SAI160 Standard Cylinder SAI160BX650S the Right Cylinder?
Selecting this 160 mm bore over the neighboring 200 mm unit avoids unnecessary oversizing, as the 200 mm bore yields 21991 N at 0.7 MPa, which may be excessive for mid-heavy loads. Conversely, stepping down to the 125 mm bore drops the output to 8590 N, which might underperform in high-inertia applications.
Because the 650 mm stroke creates a long unsupported rod extension, side loads can cause severe bending stress on the rod bearing. To prevent premature wear, implement an external guide rail or utilize a fully guided cylinder design. If the machinery requires fail-safe load holding upon air pressure loss, pair this cylinder with an external rod lock or specify the SAIL variant instead of relying on the air cushion for braking.
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.
