About the Airtac SAI100 Standard Air Cylinder SAI100X920SN
The AirTAC SAI100X920-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 920mm stroke. Because 920mm exceeds the standard maximum of 1500mm for this bore, it is produced as a non-standard, made-to-order stroke. It generates a substantial push force of 3927 N at 0.5 MPa and 5497 N at 0.7 MPa, making it well-suited for heavy-duty positioning over long linear distances.
This specific configuration includes a magnet for use with CMSE and DMSE sensor switches, which ride neatly in the dual grooves machined into the extruded aluminum barrel. It is built with a standard carbon steel piston rod and utilizes NBR seals for reliable everyday pneumatic operation. As a genuine ISO 15552 profile cylinder, it provides a dimensionally interchangeable drop-in replacement for other standard cylinders without relying on a tie-rod construction.

Where the Airtac SAI100 Standard Air Cylinder SAI100X920SN Is Used
Material Handling Ejection
Ideal for pushing heavy pallets or containers off a long conveyor line, utilizing the 920mm stroke to clear the work area completely before retraction.
Large Press Transfer
Suitable for transferring automotive panels or heavy metal sheets between press stations where a long, robust linear reach is required.
Heavy Door Actuation
Provides the extended reach and high push force necessary to open and close large industrial blast doors or heavy safety gates on factory floors.
Is the Airtac SAI100 Standard Air Cylinder SAI100X920SN the Right Cylinder?
When selecting this actuator, verify that your 920mm stroke requirement cannot be achieved by a shorter movement, as standard strokes for this bore stop at 1500mm. If your application demands less force, stepping down to an 80mm bore yields 2513 N at 0.5 MPa, which might improve cycle times and reduce air consumption. Conversely, moving up to a 125mm bore provides 6136 N at 0.5 MPa for heavier loads.
Because the stroke is 920mm, the unsupported rod length is significant; you must manage side load to prevent rod-bearing bending. Utilizing an external guide rail or a dedicated guided cylinder is strongly recommended to prevent premature wear. Furthermore, if the machinery loses air pressure, this standard cylinder will not hold its load—the piston will drift. For fail-safe position holding, consider the SAIL variant with an air-released lock or an external pilot-operated check valve. Mounting options include FA/FB flanges or TC trunnion components, and the fluid porting utilizes PT tapered G1/2 threads.

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 SAI100X920SN FAQ
