About the Airtac SAI100 Standard Air Cylinder SAI100BX900S
The AirTAC SAI100X900-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 900mm stroke. It provides a robust 3927N push force at 0.5 MPa, making it well-suited for heavy-duty material handling and large-format pressing tasks. The extruded aluminum barrel design omits tie rods, offering a clean exterior that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh or washdown environments. It is built with a magnet for use with CMSE and DMSE sensor switches, which ride neatly in the dual side grooves of the barrel. Fluid connections use PT tapered G1/2 ports, and the unit features adjustable air cushions at both ends to tame end-of-stroke impacts.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX900S Is Used
Large-Scale Pressing
Delivers 3927N of pushing force at 0.5 MPa for assembling heavy components, forming sheet metal, or securely seating large bearings over a 900mm travel distance.
Automated Material Transfer
The 900mm stroke is optimal for pushing heavy pallets or product queues between parallel conveyor lines, while the SUS304 rod resists moisture in damp factory environments.
Heavy Door Actuation
Provides the long reach and high force necessary to automate the opening and closing of large industrial machine safety doors or heavy material gates.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX900S the Right Cylinder?
Choose this 100mm bore when an application demands more thrust than the 80mm variant (which yields 2513N at 0.5 MPa) but does not yet require the massive 6136N push force of the 125mm option. The 900mm stroke provides exceptional reach for automated machinery, though at this length the unsupported rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, pair this cylinder with an external linear guide or select a guided cylinder carriage.
Because it is a true ISO 15552 profile cylinder, you can seamlessly interchange it with other ISO 15552 compliant actuators using standard mounting accessories like FA flanges or TC trunnions. Remember that the standard adjustable air cushions only decelerate the piston near stroke ends; they do not lock the rod. If your machinery must hold a load safely without continuous air pressure, integrate an external pilot-operated check valve or specify the SAIL locking variant instead.

- ✓ 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 SAI100BX900S FAQ
At a 0.5 MPa operating pressure, this 100mm bore cylinder generates 3927N of push force and 3681N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497N.
No, the standard SAI cylinder is double-acting and its adjustable air cushions only decelerate the piston at the stroke ends. To hold a vertical load without air pressure, you should use an external rod lock, a pilot-operated check valve, or the AirTAC SAIL variant.
