About the Airtac SAI100 Standard Air Cylinder SAI100AX900
The AirTAC SAI100X900 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation, delivering 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa. Its 900 mm stroke provides substantial linear travel for material handling and large-format press setups. The extruded aluminum barrel design omits tie rods for a clean exterior.
This specific configuration features an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance over standard carbon steel. It utilizes PT tapered port threads and lacks a standard magnet, though the barrel retains dual-sided sensor grooves should you later integrate CMSE or DMSE switches.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX900 Is Used
Heavy-Duty Material Lift
Lifts substantial payloads on automated assembly lines, utilizing the 900 mm stroke to elevate components between machine levels.
Long-Stroke Diverting
Actuators large pallets across wide conveyor belts, relying on the 100 mm bore to generate the force needed to overcome sliding friction.
Large-Format Pressing
Provides steady clamping pressure for woodworking or composite pressing applications where a long, controlled stroke is required.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX900 the Right Cylinder?
When sizing this actuator, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, while this 100 mm bore is necessary when your application demands the full 3927 N baseline. Because the 900 mm stroke creates a long unsupported rod extension, side loads will cause severe rod-bearing bending and premature seal wear. Manage this by pairing the cylinder with an external guide rail or selecting a fully guided cylinder to absorb lateral forces.
As a standard double-acting actuator, this model relies on adjustable air cushions at both ends to decelerate the piston and cannot hold a load if air pressure drops. If your fixture must maintain position during a pressure loss, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. For direct mounting, use ISO 15552 compatible FA/FB flanges or TC trunnions, and ensure your PT G1/2 air connections match the 100 mm bore specifications.
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 SAI100AX900 FAQ
At 0.5 MPa, 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 SAI100X900 is dimensionally interchangeable per ISO 15552, meaning it matches the mounting interface and envelope dimensions of other standard profile cylinders. You can use existing ISO 15552 mounting accessories.
