About the Airtac SAI100 Standard Air Cylinder SAI100AX85S
The AirTAC SAI100X85-S is a double-acting ISO 15552 profile cylinder delivering 3927 N of push force at 0.5 MPa. Its 85 mm stroke provides precise short-travel motion for heavy-duty handling tasks. As a genuine AirTAC component, it ensures robust performance in industrial automation.
This specific configuration includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance. The integrated magnet (-S) allows seamless operation with CMSE and DMSE sensor switches fitted into the dual-sided extruded aluminum barrel grooves.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX85S Is Used
Heavy-Duty Pressing
Provides 3927 N of thrust at 0.5 MPa for securely seating bearings and bushings into rigid housings during automated press fits.
Large Part Lift
The 85 mm stroke elevates heavy metal castings or plastic molds between conveyor tiers with stable, high-force vertical actuation.
Pallet Diversion
Actuates heavy-duty routing gates on packaging lines, utilizing the SUS420J2 rod to withstand mildly corrosive industrial washdowns.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX85S the Right Cylinder?
Selecting this 100 mm bore is ideal when 50 mm (982 N at 0.5 MPa) lacks the necessary thrust, but an 80 mm bore (2513 N at 0.5 MPa) is still insufficient for your load. The 85 mm stroke offers a compact footprint for close-proximity tooling.
To match this unit for a drop-in replacement, ensure your ISO 15552 mounting interface matches the 100 mm bore, 85 mm stroke, PT G1/2 port, and desired mounting accessory (like FA flange or TC trunnion). Because it includes a magnet, specify the -S suffix. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold loads. For position holding without live air pressure, consider the SAIL locking variant or an external rod lock.
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 SAI100AX85S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder produces 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X85-S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders, matching the 100 mm bore, 85 mm stroke, and G1/2 porting.
