About the Airtac SAI125 Standard Air Cylinder SAI125X30
The AirTAC SAI125X30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a substantial push force of 6136 N at 0.5 MPa. Its 30 mm stroke is purpose-built for short-trroke clamping and high-force ejection tasks. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that resists debris accumulation.
Configured with a standard carbon steel piston rod and PT tapered port threads, this unit is ready for rigorous industrial deployment. While this specific configuration omits the magnet, the barrel features dual-sided sensor grooves ready to accept CMSE or DMSE switches if position feedback becomes necessary.

Where the Airtac SAI125 Standard Air Cylinder SAI125X30 Is Used
Heavy-Duty Stamping
Provides the 6136 N push force required for short-stroke metal stamping, riveting, and severe-duty forming operations.
Product Ejection
Ideal for forcefully rejecting heavy or stubborn parts from conveyor lines in high-throughput manufacturing environments.
Pallet Clamping
Excels at securing heavy pallets or industrial fixtures in place during automated machining or packaging cycles.
Is the Airtac SAI125 Standard Air Cylinder SAI125X30 the Right Cylinder?
Selecting this 125 mm bore provides massive thrust for short-travel pressing. If your application requires less energy, stepping down to the 100 mm bore yields 3927 N of push force at 0.5 MPa, whereas the larger 160 mm bore generates 10053 N for extreme pressing demands. Because the 30 mm stroke is very short, rod-bearing bending is negligible, making external guides unnecessary for standard axial loads.
For drop-in compatibility, ensure your existing setup matches the ISO 15552 mounting interface, G1/2 port, and M20x1.5 rod thread. Remember that the standard adjustable air cushions only decelerate the piston near the stroke end; they do not lock the rod. If the machinery must hold a load vertically without continuous air pressure, specify the SAIL variant or utilize an external rod lock.
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 SAI125X30 FAQ
