About the Airtac SAI200 Standard Cylinder SAI200AX115
The AirTAC SAI200X115 is a double-acting ISO 15552 profile cylinder engineered for extreme thrust requirements. Delivering a substantial 15708 N of push force at just 0.5 MPa, this 200 mm bore unit is purpose-built for heavy-duty industrial automation. The 115 mm stroke provides targeted linear motion for high-force clamping or pressing operations.
Built with an extruded aluminum barrel, this model eliminates traditional tie-rods for a cleaner profile while maintaining strict dimensional interchangeability with other ISO 15552 cylinders. It features a robust SUS420J2 stainless steel piston rod (material code A) for superior corrosion and wear resistance. The pneumatic supply connects via a PT tapered G3/4 port, and adjustable air cushions at both ends absorb kinetic energy to protect machine components.

Where the Airtac SAI200 Standard Cylinder SAI200AX115 Is Used
Heavy Metal Stamping
Provides the 15708 N push force at 0.5 MPa required to form and stamp thick sheet metal in automated fabrication lines.
Industrial Pressing
Executes high-tonnage pressing and riveting tasks for automotive component assembly, utilizing adjustable cushions to decelerate the massive 200 mm piston.
Large Mold Clamping
Secures heavy injection molds and large tooling fixtures with reliable pneumatic pressure, leveraging the SUS420J2 rod for structural integrity.
Is the Airtac SAI200 Standard Cylinder SAI200AX115 the Right Cylinder?
Selecting this 200 mm bore is appropriate when applications require massive force that smaller bores cannot achieve; for context, stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The 115 mm stroke is well below the 1500 mm maximum standard stroke for this bore, keeping the rod bearing stress minimal and eliminating the need for external guides. However, because this is a double-acting cylinder, it relies on continuous air pressure to hold a load; if pressure is lost, the piston will drift. For fail-safe load holding without live pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock.
When integrating this model, match the exact mounting interface dimensions per ISO 15552. It uses a G3/4 PT port, a 40 mm cushion length, and an M36x2 rod thread. Compatible mounting accessories include TC trunnion or LB foot brackets, and because no magnet is specified (-S omitted), position sensing via CMSE or DMSE switches is not supported without modification.
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.
