About the Airtac SAI200 Standard Cylinder SAI200AX15S
The AirTAC SAI200X15-S is a double-acting ISO 15552 profile cylinder engineered for immense thrust in extremely compact short-stroke operations. It delivers a formidable 15708 N push force and 15080 N pull force at 0.5 MPa. This specific configuration features a 15 mm stroke and a built-in magnet (-S) for use with CMSE and DMSE reed switches. A PT tapered port thread ensures a tight, reliable pneumatic connection.
To withstand harsh or wash-down environments, this unit is equipped with an SUS420J2 stainless steel piston rod (material code A). The extruded aluminum barrel design integrates sensor grooves on both lateral sides, streamlining the mounting of electronic position detectors without requiring extra brackets.

Where the Airtac SAI200 Standard Cylinder SAI200AX15S Is Used
Heavy Stamping
Provides the intense 15708 N push force required to execute short-travel forming, riveting, and heavy metal stamping tasks efficiently.
High-Force Clamping
Secures massive workpieces or heavy structural molds in machining centers using its immense short-stroke holding power.
Industrial Pressing
Drives robust pressing and compacting operations where a full 200 mm bore is necessary to generate immediate, localized pressure.
Is the Airtac SAI200 Standard Cylinder SAI200AX15S the Right Cylinder?
Select this 200 mm bore variant when your application demands maximum thrust within a very short linear displacement. If your mechanism requires less force, stepping down to the 160 mm bore yields 10053 N push force at 0.5 MPa, which may suffice and saves physical footprint. Conversely, the 200 mm bore is the largest standard SAI profile size available.
Because the 15 mm stroke is very short, rod-bearing bending from side loads is minimal, but you must still ensure rigid, precise mounting to prevent binding. If your workflow demands that the load stays fixed upon total air pressure loss, do not rely on this standard cylinder; instead, specify an SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders.
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.
