About the Airtac SAI200 Standard Cylinder SAI200AX500
The AirTAC SAI200X500 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 15708 N at 0.5 MPa and a pull force of 15080 N, making it well-suited for moving substantial loads over a 500 mm stroke. The extruded aluminum barrel design omits tie-rods, offering a clean exterior that simplifies the mounting of accessories.
This configuration features an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It uses PT tapered port threads and lacks a standard magnet. For applications requiring position detection, the -S magnet option is necessary to utilize CMSE or DMSE sensors along the dual side grooves.

Where the Airtac SAI200 Standard Cylinder SAI200AX500 Is Used
Heavy Stamping
Provides the massive force required to actuate large stamping presses and form thick metal components.
Automotive Assembly
Moves heavy chassis frames or robotic welding fixtures along the production line with reliable power.
Pallet Handling
Lifts and positions fully loaded industrial pallets during automated packaging and distribution processes.
Is the Airtac SAI200 Standard Cylinder SAI200AX500 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when applications demand extremely high thrust that smaller bores cannot provide, such as lifting heavy platens. If the full 15708 N at 0.5 MPa is excessive, stepping down to a 160 mm bore yields 10053 N of push force. Conversely, if pressure drops occur in your system, this bore can generate up to 21991 N at 0.9 MPa.
Because the 500 mm stroke creates a long extension, the rod bearing is susceptible to bending under side loads. Implement external guide rails or choose a guided cylinder to prevent premature seal wear. Note that the standard SAI cannot hold a load if air pressure is lost; for fail-safe holding, consider the SAIL lock or BSAI clamp-lock variants. This model is dimensionally interchangeable per ISO 15552 and can replace other ISO 15552 profile cylinders with matching 200 mm bore, 500 mm stroke, G3/4 ports, and appropriate mounting accessories.
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.
