About the Airtac SAI125 Standard Air Cylinder SAI125X160
The AirTAC SAI125X160 is a double-acting ISO 15552 profile cylinder delivering 6136N push force at 0.5MPa. Its 160mm stroke suits heavy-duty handling tasks requiring substantial mid-stroke reach. This genuine AirTAC unit uses a standard carbon steel piston rod for high tensile durability in demanding industrial environments.
This model features PT tapered port threads and includes adjustable air cushions at both ends to absorb high kinetic energy. Because it lacks a magnet, it requires external proximity switches for position sensing rather than embedded groove sensors.

Where the Airtac SAI125 Standard Air Cylinder SAI125X160 Is Used
Heavy Stamping
Provides the robust 6136N push force needed to actuate heavy-duty stamping and forming presses.
Pallet Diverting
Executes 160mm strokes to push large loaded pallets across high-throughput material handling lines.
Automated Welding
Positions large automotive chassis components securely during robotic welding cycles.
Is the Airtac SAI125 Standard Air Cylinder SAI125X160 the Right Cylinder?
Select this 125mm bore when 80mm (2513N at 0.5MPa) is insufficient but 160mm (10053N) would over-engineer the machine. The 160mm stroke is well below the 1500mm maximum, so standard rod-bearing bending is minimal. However, for any side loads, use external guides to prevent premature seal wear.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders. To match this configuration, specify a 125mm bore, 160mm stroke, PT port threads, and no magnet. Note that a plain SAI does not hold loads safely upon air pressure loss; use the SAIL variant for pneumatic locking requirements.
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.
