About the Airtac SAI50 Standard Cylinder SAI50AX20
The AirTAC SAI50X20 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 20mm stroke. It delivers a push force of 982 N at 0.5 MPa, making it well-suited for short-trroke clamping and ejection tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that integrates seamlessly into tight machinery layouts.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. It uses PT tapered port threads and does not include a magnet, meaning it is optimized for purely mechanical actuation without requiring proximate sensor feedback.

Where the Airtac SAI50 Standard Cylinder SAI50AX20 Is Used
Short-Stroke Clamping
Ideal for holding parts firmly in place during machining or welding operations using its 982 N force.
Product Ejection
Quickly pushes finished goods off a conveyor line with a compact 20mm travel distance.
Gate Diverter
Actuates small sorting flaps or gates to direct lightweight packages on automated lines.
Is the Airtac SAI50 Standard Cylinder SAI50AX20 the Right Cylinder?
Select this 50mm bore model when you need 982 N of push force at 0.5 MPa, stepping up from the 40mm bore which provides 628 N. The 20mm stroke is ideal for rapid, short-travel movements. Because the stroke is minimal, side-load stress on the rod bearing is inherently low, though external guides are always recommended if heavy off-center loads are present.
For direct compatibility, match the 50mm bore, 20mm stroke, G1/4 port, and your required mounting accessory (such as an FA flange or LB foot). Note that this standard cylinder relies on air pressure to maintain position; if your application requires mechanical load holding upon air loss, consider the SAIL variant with an air-released lock or 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 SAI50 Standard Cylinder SAI50AX20 FAQ
