About the Airtac SAI200 Standard Cylinder SAI200AX150S
The AirTAC SAI200X150-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It delivers a substantial 15708 N of push force at 0.5 MPa, making it well-suited for high-impact pressing and lifting over its 150 mm stroke. The extruded aluminum barrel design omits tie rods, providing a clean exterior that integrates seamlessly into modern machinery.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid or mildly aggressive environments. Equipped with a magnet (-S), the barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE series switches. For operations requiring bidirectional clamping without live air pressure, the related BSAI clamp-lock variant offers a secure alternative.

Where the Airtac SAI200 Standard Cylinder SAI200AX150S Is Used
Heavy Metal Stamping
Generates 21991 N of push force at 0.7 MPa to drive heavy-duty stamping and forming presses in automotive component manufacturing.
Large Assembly Presses
Provides the robust linear motion required to seat large bearings and heavy housings within industrial assembly lines.
Pallet Handling
Lifts and positions heavy loaded pallets on automated conveyor systems, utilizing the 150 mm stroke for precise vertical elevation.
Is the Airtac SAI200 Standard Cylinder SAI200AX150S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when an application demands up to 15708 N of push force at 0.5 MPa, stepping up significantly from the 10053 N provided by the 160 mm bore size. At 150 mm stroke, the stroke length is well within the 1500 mm maximum standard stroke for this bore, so no non-standard ordering is required.
Because the standard SAI is a double-acting cylinder, it relies entirely on continuous air pressure to hold a load; if pressure is lost or the valve centers, the piston will drift. Do not rely on the adjustable air cushions at stroke ends to hold a load, as they only decelerate the piston. For position holding, consider the SAIL variant with an air-released lock or an external rod lock. When replacing an existing actuator, match the 200 mm bore, 150 mm stroke, PT tapered G3/4 port, and mounting accessory footprint for a true ISO 15552 drop-in fit.
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 SAI200 Standard Cylinder SAI200AX150S FAQ
At an operating pressure of 0.5 MPa, the SAI200X150-S delivers 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X150-S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders by matching the 200 mm bore, 150 mm stroke, and G3/4 PT porting.
