About the Airtac SAI125 Standard Air Cylinder SAI125X160S
The AirTAC SAI125X160-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It generates a robust push force of 6136 N at 0.5 MPa, making it well-suited for high-mass material handling and pressing tasks requiring a 160 mm stroke. The extruded aluminum barrel design omits tie rods, providing a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This variant includes a standard piston magnet for proximity sensing via CMSE or DMSE switches, which seat neatly into the dual sensor grooves machined into the barrel profile. The rod is constructed from durable carbon steel, and the standard tapered PT port thread ensures a secure, leak-free pneumatic connection in demanding industrial environments.

Where the Airtac SAI125 Standard Air Cylinder SAI125X160S Is Used
Heavy-Duty Stamping
Provides the substantial 6136 N push force required to form and stamp thick metal components in automated fabrication lines.
Pallet Diversion
Handles the high inertia of fully loaded pallets along heavy-transfer conveyor systems, using the 160 mm stroke to reliably push loads onto branching lanes.
Industrial Pressing
Delivers consistent downward pressure for bearing insertion and industrial assembly operations where high force and rigid positioning are mandatory.
Is the Airtac SAI125 Standard Air Cylinder SAI125X160S the Right Cylinder?
Selecting this 125 mm bore cylinder is optimal when your application demands thrust exceeding the 3927 N provided by the 100 mm variant at 0.5 MPa, but falls short of needing the 10053 N output of the 160 mm class. The 160 mm stroke offers ample travel for typical clamping and lifting cycles without requiring excessive space. Since the stroke is under 300 mm, standard rod-bearing bending is minimal, though external guides should still be used if heavy off-center loads are present.
Keep in mind that a standard double-acting cylinder does not inherently hold a load when air pressure is removed or exhausted; the piston will drift. If your machinery requires fail-safe position holding or drop prevention, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. For an exact ISO 15552 replacement match, verify the 125 mm bore, 160 mm stroke, G1/2 port, and required mounting accessory (such as TC trunnion or LB foot), and specify the -S magnet code for sensor compatibility.
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 SAI125 Standard Air Cylinder SAI125X160S FAQ
At a standard operating pressure of 0.5 MPa, this 125 mm bore cylinder generates a push force of 6136 N and a pull force of 5734 N. It can achieve a maximum theoretical push force of 1251 kgf at 1.0 MPa.
Yes, the SAI125X160-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 standard cylinders. Ensure your setup matches the G1/2 port and the required mounting accessories before installation.
