About the Airtac SAI160 Standard Cylinder SAI160AX900S
The AirTAC SAI160X900-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a substantial push force of 10053 N at 0.5 MPa and 14074 N at 0.7 MPa. Its 900 mm stroke is ideal for moving massive loads over extended linear distances in demanding industrial environments.
This specific configuration features a SUS420J2 stainless steel rod (option A) for superior corrosion and scratch resistance, a PT tapered port thread, and an integrated magnet (-S) for seamless operation with CMSE or DMSE reed sensors. The extruded aluminum barrel includes sensor grooves on both sides, ensuring flexible switch mounting without adding bulky tie-rods.

Where the Airtac SAI160 Standard Cylinder SAI160AX900S Is Used
Heavy Stamping
Provides the 14074 N force at 0.7 MPa required to actuate large mechanical presses and form thick metal components over a 900 mm travel distance.
Automotive Assembly
Drives large body panels or chassis components into welding fixtures, utilizing the 900 mm stroke to span wide robotic work cells.
Pallet Handling
Shifts heavy loaded pallets through 900 mm transfer stations, relying on the 160 mm bore's high thrust and robust construction.
Is the Airtac SAI160 Standard Cylinder SAI160AX900S the Right Cylinder?
Selecting this 160 mm bore model makes sense when the 125 mm bore (which provides 8590 N push at 0.7 MPa) lacks the necessary thrust for your heavy payloads. The 900 mm stroke operates within the 1500 mm standard limit for this bore, but the extended length requires careful mounting to prevent rod-bearing bending under side loads. Always pair this cylinder with an external guide rail or a guided carriage to absorb lateral forces.
For applications requiring position holding or drop-prevention when air pressure is lost, note that the standard adjustable air cushions only decelerate the piston near the stroke ends and do not act as a mechanical lock. To secure loads without live pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. This unit is dimensionally interchangeable per ISO 15552, offering a direct replacement for other ISO 15552 cylinders using the TC trunnion or FA flange accessories.
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 SAI160 Standard Cylinder SAI160AX900S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. It can reach a theoretical maximum force of 2050 kgf at 1.0 MPa.
For strokes of 900 mm, the unsupported rod is susceptible to bending under lateral loads. You must use external guide rails or a guided carriage to absorb side forces, preventing premature wear of the rod bearing and seals.
