About the Airtac SAI200 Standard Cylinder SAI200AX300S
The AirTAC SAI200X300-S is a double-acting ISO 15552 profile cylinder engineered for immense pushing power, generating 15708 N of thrust at just 0.5 MPa. Its 300 mm stroke provides the extended travel needed for heavy machinery, while the extruded aluminum barrel design omits tie rods for a clean, robust exterior.
This specific configuration includes a magnet for CMSE/DMSE sensor switches and features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance. It utilizes PT tapered port threads and includes adjustable air cushions at both ends to manage the massive kinetic energy of a 200 mm bore piston.

Where the Airtac SAI200 Standard Cylinder SAI200AX300S Is Used
Heavy Metal Stamping
Provides the massive 15708 N push force required to actuate large progressive die presses and heavy-gauge metal forming equipment.
Automotive Assembly Jigs
Drives large-body welding fixtures and robotic clamping arms where a 300 mm stroke is necessary to clear bulky chassis components.
Bulk Material Diverters
Powers heavy-duty logistics diverters and pallet stops, utilizing the magnet-equipped barrel for precise end-of-stroke position sensing.
Is the Airtac SAI200 Standard Cylinder SAI200AX300S the Right Cylinder?
A 200 mm bore provides exceptional force, but if your application only requires around 10053 N at 0.5 MPa, stepping down to the 160 mm bore reduces air consumption and physical footprint. For strokes of 300 mm or longer, side loads create significant bending moments on the rod bearing; always use an external guide rail or a guided cylinder to prevent premature wear.
If the machine must hold a load in place during a complete loss of air pressure, this standard cylinder will drift. The air cushions only decelerate the piston near the stroke end and do not act as a brake. For positive holding, select the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. This model is dimensionally interchangeable per ISO 15552, offering a direct drop-in replacement for other ISO 15552 profile cylinders with identical 200 mm bore, 300 mm stroke, PT ports, and FA/FB flange or TC trunnion mounts.
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.
