About the Airtac SAI125 Standard Air Cylinder SAI125X130
The AirTAC SAI125X130 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 6136 N of push force at 0.5 MPa, it is built to move serious loads. The 130 mm stroke provides the precise mid-range travel required for robust clamping and heavy part manipulation. A standard carbon steel piston rod comes equipped with PT tapered port threading, ensuring tight, leak-free pneumatic connections in demanding industrial environments.
Because this model features an extruded aluminum barrel rather than a tie-rod design, it integrates seamlessly into ISO 15552 mounting footprints. The barrel includes dual sensor grooves, allowing for easy installation of CMSE or DMSE reed switches if a magnet is specified later. For applications involving thermal extremes, the standard TPU seals can be swapped for high-temperature Viton (H) or NBR (N) alternatives to match specific operational demands.

Where the Airtac SAI125 Standard Air Cylinder SAI125X130 Is Used
Heavy-Duty Stamping
Provides the 6136 N force required to drive large stamping dies and form heavy-gauge metal components securely.
Automotive Assembly
Actuates large robotic grippers for positioning engine blocks and chassis frames during vehicle production.
Pallet Handling
Lifts and pushes fully loaded industrial pallets along high-capacity conveyor lines with reliable thrust.
Is the Airtac SAI125 Standard Air Cylinder SAI125X130 the Right Cylinder?
Selecting this 125 mm bore is appropriate when 80 mm (2513 N at 0.5 MPa) lacks the thrust for your heaviest tooling, yet a 160 mm bore would be physically oversized. The 130 mm stroke offers sufficient travel for large format presses. If your mechanism must maintain its position or hold a load vertically when air pressure is removed, this standard cylinder will drift; you should specify an SAIL variant with an air-released lock or utilize an external pilot-operated check valve. Furthermore, ensure your mounting setup uses ISO 15552 compatible accessories like TC trunnion or CA clevis brackets to handle the high kinetic energy.
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 SAI125X130 FAQ
At an operating pressure of 0.5 MPa, the SAI125X130 generates 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N.
Yes, this profile cylinder is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile cylinders, provided you match the 125 mm bore, 130 mm stroke, and G1/2 porting.
