About the Airtac SAI125 Standard Air Cylinder SAI125AX95S
The AirTAC SAI125X95-S is a double-acting profile cylinder built to strict ISO 15552 dimensional standards, ensuring a direct drop-in replacement for other ISO 15552 interface actuators. Operating at 0.15-1.0 MPa, it generates a substantial push force of 6136 N and pull force of 5734 N at 0.5 MPa, making it suited for heavy-duty positioning tasks.
This specific configuration includes a SUS420J2 stainless steel rod (material code A) for enhanced resistance against surface corrosion and scoring. The 95 mm stroke is a non-standard made-to-order length, and the integrated magnet (-S) allows seamless mounting of CMSE or DMSE sensor switches directly into the barrel's dual-side grooves.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX95S Is Used
Heavy Machinery Forming
Provides the robust clamping thrust needed to hold heavy steel plates during metal bending and industrial forming presses.
Pallet Diversion
Delivers high lateral force to actuate heavy-duty mechanical stops and diverter arms on high-mass pallet conveyor lines.
Automated Pressing
Executes precise high-force pressing operations for bearing insertion and industrial component assembly within robotic cells.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX95S the Right Cylinder?
Selecting this 125 mm bore provides a massive step up in thrust over the 100 mm bore class, which offers 3927 N push force at 0.5 MPa, pushing you firmly into heavy machinery actuation. If your application requires less force, stepping down prevents unnecessary air consumption. Because this model uses a PT tapered port thread, ensure your fittings match this standard for a leak-free seal.
For any load holding requirements without continuous air pressure, note that the standard adjustable air cushions only decelerate the piston near the end of stroke and do not lock the rod. If the machine cycle demands a fail-safe hold or drop prevention during pressure loss, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead of relying on a standard 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 SAI125AX95S FAQ
At a standard operating pressure of 0.5 MPa, this 125 mm bore cylinder provides a push force of 6136 N and a pull force of 5734 N. If operated at 0.7 MPa, the push force increases to 8590 N.
Yes, the SAI125X95-S is a genuine AirTAC profile cylinder manufactured to ISO 15552 mounting interface dimensions. It is dimensionally interchangeable with other ISO 15552 cylinders, allowing you to use existing FA/FB flanges or TC trunnion mounting accessories without modifying the machine frame.
