About the Airtac SAI125 Standard Air Cylinder SAI125AX195S
The AirTAC SAI125X195-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 6136 N of push force at 0.5 MPa, this 125 mm bore unit is built to drive demanding high-inertia loads. The 195 mm stroke provides substantial extension for large-scale machinery.
This variant is configured with an SUS420J2 stainless steel rod (code A) for superior corrosion resistance and features a built-in magnet for seamless integration with CMSE and DMSE sensor switches. Its extruded aluminum barrel incorporates sensor grooves on both sides, simplifying switch mounting.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX195S Is Used
Heavy Stamping
Generates 8590 N of thrust at 0.7 MPa, perfectly suited for driving large metal forming and heavy stamping presses.
Automotive Assembly
Provides the robust actuation needed to clamp heavy chassis components and position large vehicle sub-assemblies.
Pallet Handling
Moves heavy loaded pallets along high-capacity conveyor lines with reliable, high-force precision.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX195S the Right Cylinder?
Selecting this 125 mm bore is ideal when 100 mm cylinders (offering 3927 N push at 0.5 MPa) lack the necessary thrust for heavy payloads. If extreme reach is required beyond 195 mm, consider a larger bore to maintain rigidity. For applications needing positive load holding during air loss, standard SAI cylinders will drift; instead, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant.
This model ensures a true ISO 15552 mounting interface drop-in replacement, matching standard 125 mm bore dimensions, PT G1/2 ports, and compatible FA/FB flanges or TC trunnion accessories. The included magnet (-S) enables direct position feedback.

- ✓ 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.
