About the Airtac SAI50 Standard Cylinder SAI50AX160S
The AirTAC SAI50X160-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push thrust at 0.5 MPa. Its 160 mm stroke strikes an optimal balance for mid-range actuation, while the extruded aluminum barrel omits tie-rods for a clean, modern exterior.
This specific configuration includes a -S magnet for direct compatibility with CMSE and DMSE sensor switches, which ride securely in the dual side grooves. It is also built with an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, and features PT tapered port threads.

Where the Airtac SAI50 Standard Cylinder SAI50AX160S Is Used
Component Ejection
Provides reliable push force to eject molded parts from machinery, utilizing the 160 mm stroke to clear the work area completely.
Package Diverting
Actuates routing gates on packaging lines, where the 982 N thrust at 0.5 MPa easily redirects heavy cartons onto secondary tracks.
Pallet Stop Arms
Functions as a robust stop mechanism for pallets on gravity conveyors, holding loads securely in place while live pressure is applied.
Is the Airtac SAI50 Standard Cylinder SAI50AX160S the Right Cylinder?
Select this 50 mm bore when an application requires stepping up from a 40 mm bore's 628 N output, but a 63 mm bore's 1559 N would be excessive. The 160 mm stroke provides ample extension for standard gating and lifting tasks.
Because the stroke is 160 mm, evaluate the rod bearing for potential bending if heavy side loads are present; utilizing an external guide rail ensures smooth, non-binding travel. As a standard double-acting actuator, it relies on continuous air pressure to maintain its position—if the air supply drops, the piston will drift. For dead-load holding, consider the SAIL variant with an air-released lock. This model is dimensionally interchangeable per ISO 15552, matching bore, stroke, G1/4 port, and standard mounting accessories like FA flanges or TC trunnions.
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 SAI50 Standard Cylinder SAI50AX160S FAQ
At a 0.5 MPa operating pressure, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X160-S is dimensionally interchangeable per ISO 15552. You can drop it into existing setups matching the 50 mm bore, 160 mm stroke, and G1/4 port dimensions without modifying the mounting footprint.
