About the Airtac SAI125 Standard Air Cylinder SAI125AX130
The AirTAC SAI125X130 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 6136 N and a pull force of 5734 N at 0.5 MPa, making it well-suited for high-thrust tasks over its 130 mm stroke. The extruded aluminum barrel design omits tie rods, yielding a clean exterior that integrates seamlessly into modern machinery.
This specific configuration features a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance in humid or mildly chemically active environments. Fluid supply connects via PT tapered thread ports sized at G1/2. Note that this variant does not include a magnet; if position sensing is required, the CMSE or DMSE switches necessitate the -S magnet option.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX130 Is Used
Heavy Metal Stamping
Provides the 6136 N push force required to actuate large mechanical stamping presses and securely form thick gauge materials.
Pallet Diverting
Drives robust routing arms on high-capacity conveyor lines to redirect heavy pallets without hesitation.
Automotive Assembly
Executes heavy clamping and positioning tasks on automotive frames during automated welding procedures.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX130 the Right Cylinder?
Selecting this 125 mm bore over the smaller 100 mm version doubles your available thrust from 3927 N to 6136 N at 0.5 MPa, which is critical when moving substantial masses. If your application requires less energy or faster cycling, stepping down to an 80 mm bore yields 2513 N of push force. Because the 130 mm stroke is relatively short, side-load stress on the rod bearing is minimal compared to longer extensions.
Ensure the mounting interface matches your existing fixture via the standardized ISO 15552 dimensions. Remember that the standard SAI cylinder relies on adjustable air cushions at both ends to decelerate the piston and does not possess a mechanical brake. If your system must hold a load vertically without continuous air pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder.
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 SAI125AX130 FAQ
At an 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. At 0.7 MPa, the push force increases to 8590 N.
Yes, the SAI125X130 is dimensionally interchangeable per ISO 15552. Its standardized mounting interface allows it to serve as a direct drop-in replacement for other ISO 15552 profile cylinders, provided you match the PT G1/2 port and 130 mm stroke.
