About the Airtac SAI100 Standard Air Cylinder SAI100AX950S
The AirTAC SAI100X950-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 950mm stroke. Because this stroke exceeds the standard maximum of 1500mm for this bore, it is produced as a made-to-order configuration. It provides a robust push force of 3927 N at 0.5 MPa, making it well-suited for moving heavy loads over long linear distances.
This specific unit is built with an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance. It includes a magnetic piston (-S) for use with CMSE and DMSE sensor switches, which mount directly into the dual sensor grooves on the extruded aluminum barrel. The fluid connections use PT tapered threads.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX950S Is Used
Long-Stroke Material Handling
Drives large packaging or material handling gates over extended 950mm distances where full extension and retraction are required.
Heavy Assembly Press
Provides 3927 N of push force at 0.5 MPa to seat bearings or assemble heavy industrial components along a guided linear axis.
Automated Welding Fixture
Moves heavy welding heads into position, utilizing the SUS420J2 stainless steel rod to resist spatter and shop floor moisture.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX950S the Right Cylinder?
When sizing this ISO 15552 cylinder, stepping down to an 80mm bore yields 2513 N of push force at 0.5 MPa, while moving up to a 125mm bore increases that output to 6136 N. Choose the 100mm bore when your application requires moving substantial mass with moderate air consumption.
Because the 950mm stroke creates a long unsupported rod, side loads will cause bending stress on the rod bearing. For this made-to-order length, always use an external guide rail or a guided cylinder carriage to prevent premature wear. If the machinery loses air pressure, this standard cylinder will drift and drop its load; use the SAIL variant with an air-released lock or a BSAI clamp-lock for secure position holding. This model is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 profile cylinders. Match your mounting accessory (LB, FA, or TC) and ensure you specify the -S magnet for sensor compatibility.
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 SAI100AX950S FAQ
The SAI100X950-S generates 3927 N of push force and 3681 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 5497 N.
No, a standard double-acting SAI cylinder will drift and drop its load without live pressure. The adjustable air cushion only decelerates the piston near the stroke end. For fail-safe holding, use the SAIL lock or BSAI clamp-lock variant.
