About the Airtac SAI100 Standard Air Cylinder SAI100AX280
The AirTAC SAI100X280 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 280mm stroke. It delivers a robust 5497 N of push force at 0.7 MPa, making it well-suited for heavy-duty material handling and pressing operations. The extruded aluminum barrel design omits traditional tie rods, providing a clean exterior and integrated mounting interfaces.
This specific configuration incorporates an SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or washdown environments. Fluid connections use PT tapered G1/2 ports. For applications requiring end-position holding without continuous air pressure, consider the related SAIL lock or BSAI bidirectional clamp-lock variants, as standard pneumatic cushions only decelerate the piston and do not prevent drift.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX280 Is Used
Heavy-Duty Stamping
Provides 5497 N of thrust at 0.7 MPa for securely seating bearings or forming light gauge metal components in automated presses.
Pallet Handling
Utilizes the 280mm stroke to push heavy pallets or totes onto accumulation conveyors, withstanding harsh environments via its SUS420J2 rod.
Automated Clamping
Exerts reliable holding pressure against large workpieces during machining or welding operations, ensuring part stability.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX280 the Right Cylinder?
Selecting this 100mm bore over a smaller 80mm option upgrades your push force from 3518 N to 5497 N at 0.7 MPa, while stepping up further to a 125mm bore yields 8590 N. The 280mm stroke offers extended travel for pushing, lifting, or clamping tasks. Because this stroke exceeds 300mm is approaching the threshold where side loads cause bending, always verify your guiding mechanism if handling heavy offset loads.
As a true ISO 15552 profile cylinder, this model is dimensionally interchangeable with other ISO 15552 cylinders for drop-in replacement. Ensure your setup matches the 100mm bore, 280mm stroke, PT G1/2 port thread, and desired mounting accessory (such as FA/FB flange or TC trunnion). Note that this unit lacks a magnet; add the -S suffix if you require CMSE or DMSE sensor switches for position feedback.
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.
