About the Airtac SAI125 Standard Air Cylinder SAI125AX195
The AirTAC SAI125X195 is a double-acting ISO 15552 profile cylinder featuring a 125mm bore and a 195mm stroke. It delivers a robust 6136N push force at 0.5MPa, making it well-suited for heavy-duty actuation. This specific unit is configured with a SUS420J2 stainless steel piston rod (material code A) and PT tapered port threads.
Because the 195mm stroke deviates from the standard increments, it is produced as a non-standard, made-to-order stroke. The extruded aluminum barrel includes sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches if a magnet is specified in future revisions.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX195 Is Used
Heavy Metal Stamping
Provides the high thrust necessary for securely clamping heavy steel plates during large-scale stamping and punching operations.
Automotive Body Welding
Actuates large welding fixtures and heavy positioning gates on automotive assembly lines where substantial force is required.
Bulk Material Diversion
Drives heavy-duty diverter arms and sorting gates on conveyor systems handling dense bulk materials or pallets.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX195 the Right Cylinder?
This 125mm bore generates 6136N of thrust at 0.5MPa. If your application requires less force, stepping down to the 100mm bore yields 3927N at the same pressure. For higher force demands, the 160mm bore provides 10053N at 0.5MPa. The 195mm stroke falls below the 300mm threshold, so standard rod-bearing bending is minimal, though side loads should still be minimized.
Standard SAI cylinders do not hold loads when air pressure is removed; the piston will drift if the valve is centered or exhausted. For vertical loads requiring fail-safe holding, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. This model is dimensionally interchangeable per ISO 15552, accepting standard FA/FB flanges and CA/CB clevis mounts.
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.
