About the Airtac SAI100 Standard Air Cylinder SAI100AX850
The AirTAC SAI100X850 is a double-acting ISO 15552 profile cylinder featuring an 850mm stroke and a 100mm bore. It delivers a robust 5497N push force at 0.7 MPa, making it well-suited for heavy-duty automation tasks requiring substantial travel distance.
This variant incorporates a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid settings. It uses PT tapered port threads, and because no magnet is specified, it operates without electronic position sensing.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX850 Is Used
Material Handling
Drives large pallet stops and heavy package diverters across extended 850mm travel distances.
Automotive Assembly
Actuates heavy welding fixtures and robotic clamping arms requiring 3927N of push force at 0.5 MPa.
Wood Processing
Handles large panel routing and cutting strokes where the SUS420J2 rod resists humid environments.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX850 the Right Cylinder?
Providing 3927N of thrust at 0.5 MPa, this model sits between the 63mm bore (1559N) and the 125mm bore (6136N). Choose the 100mm bore when your application demands high force over long distances, but step up to 125mm if the load approaches 6000N.
With an 850mm stroke, the unsupported rod is highly susceptible to bending under side loads. Employ an external guide rail or a guided cylinder to prevent rod-bearing damage. Note that this cylinder relies on adjustable air cushions for end-of-stroke deceleration; it will not hold a load if air pressure drops. For position holding, consider the SAIL or BSAI variants. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any matching 100mm bore, 850mm stroke, PT port interface with standard mounting 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 SAI100 Standard Air Cylinder SAI100AX850 FAQ
At 0.5 MPa, it provides 3927N of push force and 3681N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 5497N.
Yes. The SAI100X850 is a genuine ISO 15552 profile cylinder, meaning its mounting interface and envelope dimensions are interchangeable with other ISO 15552 cylinders of the same 100mm bore and 850mm stroke.
