About the Airtac SAI160 Standard Cylinder SAI160X950S
The AirTAC SAI160X950-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty linear motion. It generates a substantial push force of 14074 N at 0.7 MPa, making it well-suited for high-inertia loads over its 950 mm stroke. The extruded aluminum barrel omits tie-rods, providing a clean exterior that resists mechanical interference.
This specific configuration includes a magnetic piston (-S) for direct mounting of CMSE or DMSE reed switches along the integrated sensor grooves on both sides of the barrel. The standard carbon steel piston rod provides robust tensile strength for industrial cycling, while the PT tapered port threads ensure a reliable, sealed pneumatic connection.

Where the Airtac SAI160 Standard Cylinder SAI160X950S Is Used
Heavy-Duty Stamping
Provides the 14074 N force necessary to form and stamp thick metal components in automated fabrication lines.
Large Press Actuation
Drives heavy machinery platens over the 950 mm stroke, relying on external guides to maintain precise parallelism.
Industrial Material Handling
Shifts substantial palletized loads or heavy workpieces between processing stations on robust transfer systems.
Is the Airtac SAI160 Standard Cylinder SAI160X950S the Right Cylinder?
Selecting this 160 mm bore over the neighboring 200 mm bore (which yields 21991 N at 0.7 MPa) is appropriate when your application requires 14074 N of push force rather than maximum thrust, allowing for a slightly lighter footprint. Conversely, stepping down to a 125 mm bore provides 8590 N, which may be insufficient for high-inertia actuation over a 950 mm extension.
Because this unit features a 950 mm stroke, the extended carbon steel rod is highly susceptible to bending under side loads. Utilizing an external guide rail or a fully guided cylinder system is strongly recommended to prevent premature rod-bearing wear. To maintain safe positioning, note that this standard cylinder will drift if air pressure is lost; for fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock variant. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct drop-in replacement for other ISO 15552 profile cylinders of the same bore and stroke, utilizing PT port threads and standard mounting accessories.
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 SAI160X950S FAQ
