About the Airtac SAI100 Standard Air Cylinder SAI100AX400S
The AirTAC SAI100X400-S is a double-acting ISO 15552 profile cylinder offering a 100mm bore and 400mm stroke. It delivers a robust 3927N push force at 0.5MPa, making it well-suited for heavy-duty positioning tasks requiring substantial travel distance.
This variant features a SUS420J2 stainless steel piston rod for enhanced corrosion resistance. The extruded aluminum barrel includes dual sensor grooves, and the integrated magnet allows direct mounting of CMSE or DMSE reed switches for precise end-of-stroke detection.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX400S Is Used
Heavy Stamping Press
Provides the high clamping force and 400mm reach needed to secure heavy metal housings during deep-draw stamping operations.
Pallet Diverter
Acts as a robust actuator to push heavy loaded pallets from a main high-speed conveyor line onto a secondary processing lane.
Automated Welding Arm
Drives a heavy welding head assembly across a 400mm span to reach various joint locations on large automotive chassis fixtures.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX400S the Right Cylinder?
Choose this 100mm bore when a 80mm cylinder falls short—its 2513N push force at 0.5MPa is significantly lower than this model's 3927N. If you need even more power, stepping up to the 125mm bore yields 6136N at 0.5MPa. The PT G1/2 port matches the standard airflow requirements for this bore size.
Because the 400mm stroke creates a long unsupported rod extension, avoid heavy side loads that could bend the rod or accelerate bearing wear. Implement an external guide rail or use a fully guided cylinder to absorb lateral forces. For applications that must hold a load vertically when air pressure drops, select the SAIL locking variant instead of relying on the standard air cushions.
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 SAI100AX400S FAQ
At an operating pressure of 0.5 MPa, this 100mm bore cylinder generates a push force of 3927N and a pull force of 3681N. At 0.7 MPa, the push force increases to 5497N.
Yes, the SAI100X400-S is dimensionally interchangeable per ISO 15552 standards. You can drop it in to replace other ISO 15552 profile cylinders with a 100mm bore and 400mm stroke, matching the G1/2 port and mounting interface.
