About the Airtac SAI100 Standard Air Cylinder SAI100AX85
The AirTAC SAI100X85 is a double-acting ISO 15552 profile cylinder featuring an 85 mm stroke and a 100 mm bore. It generates 3927 N of push force at 0.5 MPa, making it well-suited for heavy-duty pressing and clamping operations. The extruded aluminum barrel design omits tie rods, providing a clean exterior that matches standardized ISO 15552 mounting dimensions.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in harsh environments. It uses PT tapered port threads and is built without a magnet for position sensing. For applications requiring end-of-stroke feedback, the barrel includes dual sensor grooves ready to accept CMSE or DMSE switches when a magnet-equipped variant is specified.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX85 Is Used
Heavy-Duty Stamping
Provides 3927 N of thrust at 0.5 MPa for deforming or marking metal components in automated assembly lines.
Pallet Clamping
Secures heavy pallets or workpieces in place during machining or transport processes using robust 100 mm bore power.
Plastic Molding Press
Utilizes the 85 mm stroke to close molds and apply consistent holding force throughout the curing cycle.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX85 the Right Cylinder?
Selecting this 100 mm bore model provides 3927 N of thrust at 0.5 MPa, offering substantially more power than the 80 mm version which yields 2513 N. If your application requires less force, stepping down to the 80 mm bore can optimize air consumption. The 85 mm stroke is highly versatile for compact machinery.
Because this is a double-acting pneumatic actuator, it relies on continuous air pressure to move and maintain its position. If your system loses air pressure or the control valve is centered, the piston will drift and cannot hold a load. For fail-safe load holding without live pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. As a true ISO 15552 profile cylinder, this unit serves as a drop-in replacement for any standard 100 mm bore ISO 15552 actuator, utilizing a G1/2 port and compatible FA/FB flange or TC trunnion mounts.
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 SAI100AX85 FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder exerts a push force of 3927 N and a pull force of 3681 N. If pressure is increased to 0.7 MPa, the push force reaches 5497 N.
Yes, the SAI100X85 is a genuine ISO 15552 profile cylinder. Its standardized mounting interface and center-to-center dimensions allow it to serve as a drop-in replacement for other ISO 15552 cylinders of the same bore size.
