Where the Airtac SAI125 Standard Air Cylinder SAI125X130S Is Used
Heavy Stamping
Provides the high 6136 N thrust at 0.5 MPa required for firmly pressing or stamping metal components in automotive part fabrication.
Pallet Diverter
Acts as a robust diverter arm on heavy-duty roller conveyors, using its 130 mm stroke to push loaded pallets onto secondary packaging lines.
Large Clamp Jigs
Secures large workpieces inside welding or machining jigs, utilizing the magnetic piston and CMSE sensors to confirm clamp engagement to the PLC.
Is the Airtac SAI125 Standard Air Cylinder SAI125X130S the Right Cylinder?
If your application demands less force, stepping down to the 100 mm bore offers a 3927 N push force at 0.5 MPa, which might suffice for lighter loads and save space. Conversely, if you need significantly more thrust, the 160 mm bore provides 10053 N at 0.5 MPa. Because this 130 mm stroke is relatively short for this large bore, rod-bearing bending is minimal, but always ensure the load is axially aligned to prevent premature seal wear.
This unit is dimensionally interchangeable per ISO 15552, making it a drop-in replacement for other ISO 15552 profile cylinders. To replicate this exact configuration, match the 125 mm bore, 130 mm stroke, PT G1/2 port, and include the -S magnet option for sensor compatibility. Note that a standard double-acting cylinder like this relies on continuous air pressure to hold a load; if pneumatic pressure is lost, the piston will drift. For fail-safe load holding without live pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead of relying on the adjustable air cushions, which only decelerate the piston near the stroke ends.
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.
