About the Airtac SAI100 Standard Air Cylinder SAI100BX85S
The AirTAC SAI100X85-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning tasks. Operating at 0.5 MPa, it provides a push thrust of 3927 N and a pull thrust of 3681 N. The 85 mm stroke is tailored for short, high-force clamping or ejection movements.
This specific configuration incorporates a SUS304 stainless steel piston rod (material code B), ensuring superior corrosion resistance in washdown or chemically exposed environments. It is equipped with a magnetic piston (-S) that interfaces seamlessly with CMSE and DMSE sensor switches, utilizing the dual extruded sensor grooves on the aluminum barrel for precise position feedback.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX85S Is Used
Heavy-Duty Stamping
Drives robust metalforming and stamping presses where the 3927 N push force at 0.5 MPa is required to deform or seat solid components securely.
Pallet Diversion
Actuates heavy-duty pallet sorting gates and diverters, utilizing the 85 mm stroke and integrated CMSE sensors for reliable mid-transfer positioning.
Plastic Molding Ejector
Ejects dense molded parts from injection machinery, leveraging the SUS304 rod for resilience against high-temperature off-gassing and occasional resin splatter.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX85S the Right Cylinder?
Select this 100 mm bore actuator when an application requires upward of 3927 N of push force at 0.5 MPa but does not warrant the larger 125 mm bore (which yields 6136 N). For setups needing less than 3500 N, stepping down to the 80 mm bore is advised to conserve compressed air. Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal, though external guides should still be used to prevent lateral binding.
As a genuine ISO 15552 profile cylinder, it serves as a direct dimensional drop-in replacement for other ISO 15552 actuators. Ensure your setup matches the 100 mm bore, 85 mm stroke, G1/2 port (available in PT tapered thread), and utilizes standard mounting accessories like FA/FB flanges or TC trunnions. To maintain a locked position without live air pressure, integrate the SAIL variant or an external rod lock, as the standard adjustable air cushions only decelerate the piston at stroke ends.
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 SAI100BX85S FAQ
