About the Airtac SAI200 Standard Cylinder SAI200AX165S
The AirTAC SAI200X165-S is a genuine ISO 15552 double-acting profile cylinder engineered for immense pushing and pulling tasks. Delivering a theoretical push force of 15708 N at 0.5 MPa, this 200 mm bore unit is built for heavy-duty industrial cycles. The 165 mm stroke provides substantial linear travel for moving large masses or actuating heavy tooling.
This specific configuration includes a factory-installed magnet (-S) enabling direct mounting of CMSE or DMSE electronic sensors along the extruded aluminum barrel's dual grooves. Furthermore, the piston rod is constructed from SUS420J2 stainless steel (option A) for superior corrosion resistance, and it utilizes PT tapered port threads to ensure robust, leak-free pneumatic connections.

Where the Airtac SAI200 Standard Cylinder SAI200AX165S Is Used
Heavy Metal Stamping
Provides the extreme tonnage required to form thick metal sheets and operate massive mechanical presses.
Large Mold Clamping
Exerts uniform, high-force pressure to secure heavy industrial injection molds during production cycles.
Hydraulic Press Override
Acts as a pneumatic override or ejection mechanism for heavy hydraulic press systems requiring slow, deliberate movement.
Is the Airtac SAI200 Standard Cylinder SAI200AX165S the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when a system demands maximum thrust that smaller bores cannot provide, such as replacing two 160 mm cylinders (10053 N each at 0.5 MPa) with a single, more powerful actuator. For applications requiring less force and faster cycling, stepping down to a 125 mm bore (6136 N at 0.5 MPa) saves space and air consumption. Because the 165 mm stroke is relatively short for this massive bore, side-load stress on the rod bearing is minimized, though external guides are still recommended for heavy payloads.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard cylinder matching those interface dimensions. Remember that the adjustable air cushions at both ends only decelerate the piston at stroke end; they do not lock the rod. If your machinery must hold a vertical load securely without continuous air pressure, integrate an external pilot-operated check valve or select the SAIL variant with an air-released lock.
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 SAI200AX165S FAQ
At 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. It can reach up to 21991 N push force at 0.7 MPa.
Yes, the SAI200X165-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts designed for standard ISO 15552 profile cylinders, provided your port and rod thread clearances are met.
