About the Airtac SAI100 Standard Air Cylinder SAI100BX900
The AirTAC SAI100X900 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 900mm stroke. It generates a push force of 3927 N at 0.5 MPa, making it well-suited for heavy-duty automation tasks requiring substantial linear displacement. The extruded aluminum barrel omits tie-rods, providing a smooth exterior that simplifies cleaning and integration into modern machinery.
This configuration includes a SUS304 stainless steel piston rod (material code B), offering superior corrosion resistance for humid or washdown environments. The fluid ports use a PT tapered thread type, and because no magnet is specified, it ships without sensor grooves utilized for reed switches. Operating at a speed range of 30-800 mm/s, it features adjustable air cushions at both ends to absorb kinetic energy at the stroke extremes.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX900 Is Used
Large Press Ejection
Provides the 3927 N of force needed to eject heavy stamped parts from large press beds over a 900mm travel distance.
Pallet Transfer System
Pushes heavy loaded pallets between conveyor lines, utilizing the full 900mm stroke to bridge wide machine gaps.
Automated Welding Indexing
Moves heavy welding fixtures into position, relying on the SUS304 rod for resistance against weld spatter and shop floor debris.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX900 the Right Cylinder?
Stepping down to an 80mm bore reduces the push force to 2513 N at 0.5 MPa, which may be insufficient for high-inertia loads. Stepping up to a 125mm bore yields 6136 N but requires a slower 30-500 mm/s speed limit. Because this 900mm stroke creates a long unsupported rod, side loads can cause severe bending stress on the rod bearing. To manage this, implement an external guide rail or select a guided cylinder to prevent premature wear.
If the application requires the load to be held in place without continuous air pressure, a standard SAI cylinder will drift or drop when pressure is lost or the valve is centered. For secure mid-stroke holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This model serves as a direct dimensional direct replacement for any ISO 15552 cylinder with a 100mm bore, 900mm stroke, PT G1/2 ports, and standard mounting accessories like FA flanges or 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.
Airtac SAI100 Standard Air Cylinder SAI100BX900 FAQ
At an operating pressure of 0.5 MPa, the SAI100X900 generates a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
The SAI100X900 is dimensionally interchangeable with any ISO 15552 standard cylinder of the same bore and stroke. It matches standard mounting interfaces and G1/2 ports, serving as a direct replacement.
