About the Airtac SAI160 Standard Cylinder SAI160BX125
The AirTAC SAI160X125 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a robust push force of 10053 N at 0.5 MPa. This specific configuration is built to order with a SUS304 stainless steel piston rod (option B) for superior moisture and corrosion resistance, alongside PT tapered port threads. Its extruded aluminum barrel design omits traditional tie rods, presenting a clean exterior that integrates seamlessly into demanding industrial environments.
Because this model lacks a magnetic piston, it is optimized for pure pneumatic actuation rather than electronic position sensing. The cylinder incorporates adjustable air cushions at both ends, requiring a 50 mm cushion stroke to effectively decelerate massive loads. For operations requiring end-of-stroke feedback, the related SAID double-rod series or the standard SAI with the -S magnet option should be evaluated instead.

Where the Airtac SAI160 Standard Cylinder SAI160BX125 Is Used
Heavy Metal Stamping
Provides the 10053 N push force at 0.5 MPa required for stamping and forming thick metal components in automated fabrication lines.
Large Mold Clamping
Secures sizable injection molds or heavy fixtures during processing, relying on the SUS304 rod to resist environmental moisture.
Pallet Diverting
Handles the redirection of fully loaded pallets on high-throughput packaging conveyors where substantial side-force resistance is required.
Is the Airtac SAI160 Standard Cylinder SAI160BX125 the Right Cylinder?
Generating 10053 N of push force at 0.5 MPa, this 160 mm bore is a significant step up from the 125 mm bore (6136 N) and is ideal for pressing, lifting, and heavy clamping. If your application requires less force, dropping to the 125 mm bore saves air consumption and physical footprint. Conversely, if you need to move extreme masses, the 200 mm bore offers 15708 N at the same pressure.
This 125 mm stroke keeps the unsupported rod length manageable, but any side loads will still rapidly accelerate wear on the rod bushing and seals. Employ an external guide rail or a fully guided cylinder to absorb lateral stresses. Furthermore, the standard SAI cannot maintain a load if air pressure drops; utilize the SAIL variant with an air-released lock or the BSAI clamp-lock for fail-safe holding. As a true ISO 15552 cylinder, it serves as a dimensionally interchangeable direct replacement for other ISO 15552 profile cylinders, utilizing a G3/4 port and compatible LB foot or TC trunnion mounts.
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 SAI160BX125 FAQ
At an operating pressure of 0.5 MPa, the SAI160X125 generates a push force of 10053 N and a pull force of 9425 N. At 0.7 MPa, the push force increases to 14074 N.
No, the standard SAI cylinder will drift or drop if air pressure is lost or exhausted. For vertical load-holding applications, you should use the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder.
