About the Airtac SAI100 Standard Air Cylinder SAI100X900SN
The AirTAC SAI100X900-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for high-impact operations requiring substantial linear thrust over an extended 900 mm stroke.
This specific configuration includes a standard carbon steel piston rod and durable NBR seals, ensuring reliable performance in standard operating temperatures. The integrated magnet (-S) allows seamless interaction with CMSE and DMSE reed switches housed within the dual sensor grooves machined into the extruded aluminum barrel.

Where the Airtac SAI100 Standard Air Cylinder SAI100X900SN Is Used
Automotive Body Welding
Provides the substantial 3927 N force required to hold and clamp heavy chassis panels securely in place during robotic welding operations over a long 900 mm reach.
Pallet Transfer Systems
Pushes fully loaded pallets between adjacent conveyor lines, utilizing the extended stroke and adjustable end cushions to manage heavy masses smoothly without harsh impacts.
Large Press Loading
Feeds heavy sheet metal blanks into large mechanical presses, where the carbon steel rod and NBR seals withstand the rigorous, high-cycle demands of industrial stamping facilities.
Is the Airtac SAI100 Standard Air Cylinder SAI100X900SN the Right Cylinder?
With a 900 mm stroke, this model operates near the upper limit of the standard 1000 mm range for this bore size. If an application requires less force, stepping down to the 80 mm bore yields 2513 N at 0.5 MPa. For extended strokes like this, side-load on the rod bearing increases significantly; utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent rod bending and premature wear.
As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders without relying on tie-rod construction. Note that the adjustable air cushions at both ends only decelerate the piston near stroke limits; they do not hold a load. If position holding without live air pressure is required, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. Mounting options include FA/FB flanges, and the PT port thread type matches the standard G1/2 porting for this bore.
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 SAI100X900SN FAQ
At a standard operating pressure of 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
No, the standard SAI cylinder does not hold position without live air pressure. The adjustable air cushions only decelerate the piston at the stroke ends. For dead-load holding, use the SAIL or BSAI locking variants, or an external pilot-operated check valve.
