About the Airtac SAI125 Standard Air Cylinder SAI125AX105
The AirTAC SAI125X105 is a double-acting ISO 15552 profile cylinder featuring a 125mm bore and 105mm stroke. It provides a robust push force of 6136 N at 0.5 MPa, making it well-suited for heavy-duty pressing and lifting tasks. The extruded aluminum barrel design omits tie-rods, offering a clean exterior that easily integrates into modern machinery.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. It uses PT tapered port threads and lacks a magnet; if position detection is required later, a -S variant with dual-side sensor grooves for CMSE or DMSE switches is necessary.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX105 Is Used
Heavy-Duty Stamping
Generates 6136 N of thrust at 0.5 MPa, ideal for driving short-stroke stamping and forming presses in metal fabrication lines.
Automated Clamping
Provides reliable, high-force holding power for securing large automotive components or heavy weldments during machining operations.
Pallet Lifting
Excels in heavy payload lifting and indexing on conveyor systems where robust 125mm bore power is required to move substantial loads.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX105 the Right Cylinder?
Select this 125mm bore actuator when a 100mm bore cylinder falls short—delivering 3927 N at 0.5 MPa—and before stepping up to a 160mm bore that yields 10053 N. The 105mm stroke is optimal for short-travel, high-force clamping operations. For applications requiring the load to remain safely suspended without continuous air pressure, select the SAIL locking variant or an external pilot-operated check valve, as the SAI's adjustable air cushions only decelerate the piston near stroke end.
As a true ISO 15552 profile cylinder, this model serves as a drop-in replacement for other standard 125mm bore actuators. Ensure your setup matches the G1/2 port size, M27x2 rod thread, and appropriate mounting accessories like TC trunnion or CA clevis brackets.
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.
