About the Airtac SAI100 Standard Air Cylinder SAI100AX155S
The AirTAC SAI100X155-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 5497 N of push force at 0.7 MPa, this 100mm bore unit is tailored for demanding workloads. The 155mm stroke provides the exact travel needed for specialized clamping and lifting tasks. It features a built-in magnet for proximity sensing.
This specific configuration incorporates a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or washdown environments. The barrel is an extruded aluminum profile with sensor grooves on both sides, allowing flexible mounting of CMSE or DMSE reed switches. It uses PT tapered port threads and includes adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX155S Is Used
Heavy-Duty Stamping
Provides the necessary 5497 N push force at 0.7 MPa to actuate medium-tonnage stamping and forming presses reliably.
Pallet Diverting
Utilizes the 155mm stroke to push heavy pallets across diverter lanes on high-throughput packaging conveyors.
Automated Welding Clamps
The SUS420J2 stainless steel rod resists weld spatter and shop debris while holding parts firmly in automated robotic cells.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX155S the Right Cylinder?
Selecting this 100mm bore cylinder makes sense when your application requires substantial thrust that smaller bores cannot provide, stepping up from the 63mm bore which yields 2182 N at 0.7 MPa. If you need even higher force, the 125mm bore offers 8590 N at the same pressure. The 155mm stroke is a non-standard length, ideal for machines requiring specific intermediate travel without the bulk of a 160mm or 200mm standard stroke.
Because this is a double-acting pneumatic actuator, it relies on continuous air pressure to hold its position; the piston will drift if pressure is lost or the valve is centered. For applications requiring fail-safe load holding, consider the SAIL variant with an air-released lock, or the BSAI bidirectional clamp-lock cylinder. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders, matching standard mounting dimensions for FA, FB flanges, and TC trunnions.
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 SAI100 Standard Air Cylinder SAI100AX155S FAQ
At an operating pressure of 0.7 MPa, this 100mm bore cylinder generates 5497 N of push force and 3681 N of pull force. The maximum theoretical force at 1.0 MPa is 801 kgf.
Yes, the -S suffix indicates a built-in magnet, making it fully compatible with CMSE and DMSE sensor switches. It is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are interchangeable with other ISO 15552 standard cylinders.
