About the Airtac SAI80 Standard Air Cylinder SAI80AX750S
The AirTAC SAI80X750-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust push force of 2513 N at 0.5 MPa, it integrates a 750 mm stroke to drive large mechanisms over extended distances. This genuine AirTAC unit features a built-in magnet (-S) enabling direct mounting of CMSE or DMSE sensor switches along the dual extruded barrel grooves.
Tailored for demanding environments, this configuration utilizes a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance. It connects via PT tapered G3/8 ports and relies on adjustable air cushions at both ends to decelerate the payload smoothly across its 30-800 mm/s speed range.

Where the Airtac SAI80 Standard Air Cylinder SAI80AX750S Is Used
Material Handling Diversion
Actuates large lane diverters and heavy-duty pushers on high-throughput packaging conveyors, utilizing the full 750 mm stroke to shift substantial product loads reliably.
Press Ejection Systems
Provides the robust 2513 N retraction force needed to extract heavy stamped parts from machining centers, while the SUS420J2 rod withstands coolant exposure.
Pallet Handling Gates
Drives heavy pallet stop gates and lifting mechanisms in automated storage systems, relying on adjustable air cushions to halt massive payloads smoothly.
Is the Airtac SAI80 Standard Air Cylinder SAI80AX750S the Right Cylinder?
Selecting this 80 mm bore over the smaller 63 mm variant increases your 0.5 MPa push thrust from 1559 N to 2513 N, providing the necessary power for high-inertia loads. If your application requires even greater force, stepping up to the 100 mm bore yields 3927 N. At a 750 mm stroke, the unsupported piston rod is highly susceptible to bending under side loads; utilizing an external guide rail or a fully guided cylinder is critical to prevent premature rod-bearing wear.
This model is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other standard profile cylinders with an 80 mm bore, 750 mm stroke, G3/8 port, and a magnet. Remember that standard double-acting cylinders drift when air pressure is removed; if your system needs static position holding, consider the SAIL locking variant or an external pilot-operated check valve.
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 SAI80 Standard Air Cylinder SAI80AX750S FAQ
