About the Airtac SAI125 Standard Air Cylinder SAI125AX95
The AirTAC SAI125X95 is a double-acting ISO 15552 profile cylinder offering 6136N push force at 0.5MPa. Its 95mm stroke handles heavy-duty positioning tasks. This extruded aluminum barrel omits tie-rods for a clean exterior.
Configured with an SUS420J2 stainless steel rod (option A), it resists corrosion in humid environments. PT tapered ports seal securely, while adjustable air cushions at both ends manage heavy moving masses.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX95 Is Used
Heavy Stamping
Provides the robust 6136N push force needed to drive heavy stamping and forming presses.
Automotive Assembly
Actuates large clamps and heavy structural fixtures securely along the 95mm stroke.
Pallet Handling
Lifts and diverts heavy pallets on high-throughput packaging and logistics conveyors.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX95 the Right Cylinder?
This 125mm bore generates 6136N at 0.5MPa; step down to an 80mm bore (2513N) for lighter loads, or up to 160mm (10053N) for massive force. Since the standard SAI cannot hold a load without air pressure, use the SAIL variant for pneumatic locking needs.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 profile cylinders. Mount via FA flange or CA clevis accessories, and add the -S magnet if CMSE or DMSE sensors are required.
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.
