About the Airtac SAI100 Standard Air Cylinder SAI100AX400
The AirTAC SAI100X400 is a double-acting ISO 15552 profile cylinder delivering 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa. This 100mm bore and 400mm stroke combination is built for heavy-duty industrial handling. It features a genuine ISO 15552 mounting interface, making it a drop-in replacement for other standard profile cylinders.
To handle demanding environments, this specific configuration uses an SUS420J2 stainless steel rod (material code A) for superior corrosion resistance. The barrel is extruded aluminum with dual sensor grooves for CMSE or DMSE switches. It uses PT tapered port threads and includes adjustable air cushions at both ends to manage kinetic energy.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX400 Is Used
Heavy Material Handling
Lifts and transfers heavy pallets or metal sheets using 5497 N of thrust at 0.7 MPa.
Automated Press Feed
Pushes large blanks into hydraulic presses with a 400mm stroke and adjustable cushions.
Large Clamp Actuation
Actuates robust welding clamps where the SUS420J2 rod resists weld spatter corrosion.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX400 the Right Cylinder?
Step down to an 80mm bore if your application only requires 2513 N at 0.5 MPa, or step up to 125mm for 6136 N. At 400mm stroke, the unsupported rod length is significant; side loads will cause rod-bearing bending. Use an external guide rail or a guided cylinder to prevent premature seal wear.
This model uses PT tapered G1/2 ports and a 25mm rod with M20x1.5 threads. It is a double-acting cylinder and does not hold position if air pressure is lost. For dead-end holding, use the SAIL air-released lock variant or an external pilot check valve. Standard mounting accessories include FA/FB flanges and TC trunnions.
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.
