About the Airtac SAI100 Standard Air Cylinder SAI100AX850S
The AirTAC SAI100X850-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N push force at 0.5 MPa, it handles substantial loads with precision. This 850 mm stroke variant is built to exacting ISO dimensional standards, ensuring seamless integration into existing setups.
This specific configuration includes a magnet for use with CMSE and DMSE sensor switches, fitting neatly into the dual-side grooves of the extruded aluminum barrel. The piston rod utilizes SUS420J2 stainless steel for superior corrosion resistance, and the pneumatic ports feature a PT tapered thread design. Adjustable air cushions at both ends manage the kinetic energy of this long-stroke, high-force actuator.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX850S Is Used
Heavy Stamping Press
Provides the high 3927 N push force required to actuate large stamping dies and forming presses over a long 850 mm travel distance.
Pallet Diversion
Extends fully to push heavy pallets across wide conveyor lines, utilizing the magnetic piston for end-of-stroke confirmation.
Large Door Actuation
Opens and closes substantial industrial machine doors or safety gates, relying on the SUS420J2 rod for environmental resilience.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX850S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant significantly upgrades thrust, jumping from 2513 N to 3927 N at 0.5 MPa. If your application requires even more power, stepping up to the 125 mm bore yields 6136 N. Because this model features an 850 mm stroke, the extended rod is highly susceptible to bending under side loads. Implementing an external guide rail or utilizing a guided cylinder carriage is strongly recommended to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 100 mm bore ISO 15552 unit. Be sure to pair it with appropriate mounting accessories like FA flanges or TC trunnions to match your machine geometry. Note that while the adjustable cushions decelerate the piston at stroke ends, this standard cylinder does not hold position if air pressure drops; use the SAIL or BSAI variants for fail-safe load locking.
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 SAI100AX850S FAQ
