About the Airtac SAI160 Standard Cylinder SAI160AX550
The AirTAC SAI160X550 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a substantial push force of 10053 N at 0.5 MPa and 14074 N at 0.7 MPa. This 160 mm bore, 550 mm stroke configuration is tailored for high-load industrial tasks requiring significant linear thrust. As a genuine ISO 15552 standard cylinder, it features an extruded aluminum barrel without tie-rods, ensuring a direct replacement for other ISO 15552 cylinders.
This specific model is configured with an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads and operates without a magnet. If your application involves extreme thermal conditions, this cylinder series supports Viton (H) seals for high-temperature environments, which can be specified on made-to-order units.

Where the Airtac SAI160 Standard Cylinder SAI160AX550 Is Used
Heavy Stamping
Provides the intense 14074 N thrust required to actuate large mechanical stamping presses and heavy-gauge metal forming equipment.
Bulk Material Handling
Drives heavy-duty diverter gates and large bulk material chutes in mining and aggregate processing facilities.
Large Mold Clamping
Secures substantial injection molds or heavy industrial fixtures, utilizing the 550 mm stroke to accommodate wide mold openings.
Is the Airtac SAI160 Standard Cylinder SAI160AX550 the Right Cylinder?
Selecting this 160 mm bore is ideal when 100 mm or 125 mm cylinders fall short on thrust, stepping up from the 125 mm bore's 8590 N push at 0.7 MPa to a robust 14074 N. When designing your pneumatic circuit, note that this cylinder does not hold its position if air pressure is lost; for fail-safe load holding, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. To match this ISO 15552 footprint, ensure your mounting accessory (such as a TC trunnion or CA clevis), 550 mm stroke, G3/4 port, and rod thread (M36x2) are correctly specified.
Because the stroke is 550 mm, the unsupported rod length is significant. Long rods are prone to bending under side loads, which can cause premature wear on the rod bearing. To manage this, use an external guide rail or select a guided cylinder to absorb lateral forces and prevent mechanical failure.
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 SAI160AX550 FAQ
At an operating pressure of 0.7 MPa, the SAI160X550 generates a push force of 14074 N and a pull force of 9425 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
Yes, the SAI160X550 is a profile-barrel cylinder dimensionally interchangeable per ISO 15552. It serves as a direct replacement for other ISO 15552 standard cylinders, provided the G3/4 port and M36x2 rod thread match your existing setup.
