About the Airtac SAI100 Standard Air Cylinder SAI100X900S
The AirTAC SAI100X900-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty linear motion. Delivering a robust 3927 N of push force and 3681 N of pull force at 0.5 MPa, this 100 mm bore actuator handles substantial payloads with ease. The generous 900 mm stroke is ideal for demanding transfer and positioning tasks across extended distances.
This specific configuration includes a built-in magnet (-S) for proximity sensing, allowing seamless integration with CMSE or DMSE reed switches via the dual sensor grooves on the extruded aluminum barrel. It features a standard carbon steel piston rod and PT tapered port threads, ensuring reliable, leak-free pneumatic connections in rigorous industrial environments.

Where the Airtac SAI100 Standard Air Cylinder SAI100X900S Is Used
Automotive Body Welding
Transfers heavy chassis components between robotic welding stations over a 900mm travel distance, utilizing the 3927N thrust to push heavy fixtures reliably.
Pallet Handling System
Indexes large loaded pallets along an assembly line, where the extended stroke and dual adjustable cushions absorb the high kinetic energy of heavy masses.
Automated Storage Retrieval
Deploys deep into storage racks to extract goods, relying on the -S magnet and CMSE sensors to confirm exact end-of-stroke positioning for the control system.
Is the Airtac SAI100 Standard Air Cylinder SAI100X900S the Right Cylinder?
When sizing this actuator, stepping down to an 80 mm bore reduces the 0.5 MPa push force to 2513 N, while the 100 mm bore provides the optimal balance of thrust and air consumption for mid-heavy loads. Because the 900 mm stroke generates significant extension lengths, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, utilize an external guide rail or select a guided cylinder to absorb lateral forces.
This unit is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders. To replicate this exact setup, match the 100 mm bore, 900 mm stroke, PT G1/2 port, and specify the -S magnet option for sensor tracking. Note that the adjustable air cushions at both ends decelerate the piston near stroke ends but do not lock the load; if position holding is required without air pressure, 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 SAI100X900S FAQ
At 0.5 MPa, the SAI100X900-S generates 3927 N of push force and 3681 N of pull force. If higher pressure is utilized, it can reach up to 5497 N at 0.7 MPa.
Yes, the SAI100X900-S is dimensionally interchangeable with other ISO 15552 profile cylinders. You can use it as a drop-in replacement by matching the 100mm bore, 900mm stroke, G1/2 port, and mounting accessories.
