About the Airtac SAI160 Standard Cylinder SAI160BX45S
The AirTAC SAI160X45-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a substantial push force of 10053 N at just 0.5 MPa. Its short 45 mm stroke is specifically optimized for high-force clamping and holding tasks. Because it meets ISO 15552 dimensional standards, it serves as a direct replacement for other standard profile cylinders without requiring machinery redesign.
This specific configuration includes a -S magnet for use with CMSE and DMSE sensor switches, fitting neatly into the extruded aluminum barrel's dual sensor grooves. Furthermore, it is equipped with a SUS304 stainless steel rod (material code B) for superior corrosion resistance, and utilizes PT tapered port threads to ensure a robust, leak-free pneumatic connection in demanding industrial environments.

Where the Airtac SAI160 Standard Cylinder SAI160BX45S Is Used
Heavy-Duty Metal Stamping
Provides the intense 10053 N force required to hold heavy steel workpieces securely in place during aggressive stamping and punching operations.
Injection Molding Extraction
The short 45 mm stroke offers rapid, brute-strength extraction of dense molded parts from tight machine cavities, enhanced by the durable SUS304 rod.
Industrial Press Clamping
Ideal for applying sustained, high-tonnage clamping pressure on large industrial presses where a compact retracted length and massive thrust are mandatory.
Is the Airtac SAI160 Standard Cylinder SAI160BX45S the Right Cylinder?
Selecting this 160 mm bore over the neighboring 125 mm option makes sense when your application requires exceeding the 125 mm bore's 6136 N push force at 0.5 MPa, providing a massive leap to 10053 N. Conversely, if your load demands less than 6000 N, stepping down to the 125 mm bore saves both physical envelope space and air consumption.
Although the 45 mm stroke keeps the rod bearing load minimal, users must remember that standard SAI cylinders cannot maintain position or hold a load if air pressure drops. The adjustable air cushion only decelerates the piston at stroke end. For true fail-safe load holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. To match existing mounting footprints, utilize standard ISO 15552 accessories like TC trunnion or LB foot mounts, and ensure your air supply matches the G3/4 port size.
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 SAI160 Standard Cylinder SAI160BX45S FAQ
At a standard 0.5 MPa operating pressure, this 160 mm bore cylinder generates a push force of 10053 N and a pull force of 9425 N. If pressure is increased to 0.7 MPa, the push force rises to 14074 N.
No, the standard SAI series relies on air pressure for movement and its cushion only decelerates the piston at the end of the stroke. If air is lost, the load will drop. For secure vertical load holding, you should use the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder.
