Where the Airtac SAI125 Standard Air Cylinder SAI125BX175S Is Used
Heavy Metal Stamping
Provides the high kinetic energy and 6136N thrust required to drive heavy stamping and forming presses reliably.
Automotive Assembly
Actuates large robotic clamping fixtures and heavy component positioning systems on automotive production lines.
Pallet Handling
Pushes and diverts heavy loaded pallets along conveyor systems, utilizing the full 175mm stroke for smooth transfers.
Is the Airtac SAI125 Standard Air Cylinder SAI125BX175S the Right Cylinder?
Select this 125mm bore when 80mm cylinders fall short, providing 2513N at 0.5 MPa, or when you need to step up to 160mm for 10053N of thrust. The 175mm stroke offers substantial travel without requiring the extended guide rails of longer 300mm-plus strokes.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any cylinder matching this standard mounting interface. Remember that standard air cushions only decelerate the piston; they will not hold a load if air pressure drops. For secure position holding, consider the SAIL or BSAI variants.
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.
