About the Airtac SAI50 Standard Cylinder SAI50AX145
The AirTAC SAI50X145 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 145mm stroke. It generates 982N of push force at 0.5 MPa, making it well-suited for mid-range handling tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists contamination.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. It uses PT tapered port threads and lacks a magnet, meaning it is optimized for purely mechanical actuation without requiring position sensing.

Where the Airtac SAI50 Standard Cylinder SAI50AX145 Is Used
Package Diverting
Provides the 982N force needed to push packages smoothly onto secondary packaging lines at 0.5 MPa.
Clamping Fixtures
Holds medium-weight workpieces securely during machining or assembly operations without requiring sensors.
Product Ejection
Uses the 145mm stroke to push finished molded parts out of press machines reliably.
Is the Airtac SAI50 Standard Cylinder SAI50AX145 the Right Cylinder?
If your application requires less force, stepping down to the 40mm bore yields 628N at 0.5 MPa, while moving up to the 63mm bore provides 1559N for heavier loads. Because this is a 145mm stroke, side-load risks are minimal, but always ensure the load is guided to prevent rod-bearing wear. Remember that a standard SAI cylinder will drift if air pressure is lost; for fail-safe load holding, consider the SAIL variant with an air-released lock or the BSAI clamp-lock type. To match this exact unit, specify a 50mm bore, 145mm stroke, PT G1/4 ports, and no magnet (-S omitted).
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.
