About the Airtac SAI100 Standard Air Cylinder SAI100BX85
The AirTAC SAI100X85 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 3927 N at 0.5 MPa and a pull force of 3681 N, making it well-suited for high-thrust pressing and clamping tasks over its 85 mm stroke. The extruded aluminum barrel design omits tie rods, ensuring a rigid yet streamlined structure.
Built to handle demanding environments, this specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance. It utilizes tapered PT ports and lacks a piston magnet. If your application requires position sensing, you would need the -S variant to accommodate CMSE or DMSE switches in the dual sensor grooves.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX85 Is Used
Heavy-Duty Pressing
Delivers 3927 N of push force at 0.5 MPa for securely stamping, riveting, or seating heavy industrial components.
Rigid Clamping
Holds large metal or composite workpieces firmly in place during machining, welding, or assembly processes.
Pallet Stopping
Acts as a high-force stopper on heavy-duty conveyor lines to halt pallets loaded with substantial materials.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX85 the Right Cylinder?
Selecting this 100 mm bore provides significantly more thrust than the 80 mm version (2513 N at 0.5 MPa), stepping up to 3927 N without jumping to the massive 125 mm class. Because the stroke is only 85 mm, rod-bearing bending is minimal, but always ensure the load is axially aligned to prevent premature seal wear.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard ISO 15552 unit with a 100 mm bore, 85 mm stroke, G1/2 port, and your chosen mounting accessory (such as FA flange or TC trunnion). Note that a standard SAI cannot hold a load if air pressure drops; for fail-safe holding, consider the SAIL or BSAI variants.
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 SAI100BX85 FAQ
At a standard 0.5 MPa operating pressure, this 100 mm bore cylinder generates 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 is a genuine ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke, utilizing a G1/2 port and standard mounting interfaces.
