About the Airtac SAI50 Standard Cylinder SAI50X20
The AirTAC SAI50X20 is a double-acting ISO 15552 profile cylinder engineered for short-stroke automation. Delivering 982N of push force at 0.5MPa, this 50mm bore unit is built for rapid, compact actuation. Its 20mm stroke excels in space-constrained mechanisms requiring immediate high-impact energy.
This model features a robust extruded aluminum barrel with integrated sensor grooves on both sides for direct CMSE or DMSE switch mounting. The standard carbon steel piston rod provides reliable durability for industrial cycling, while the PT tapered port thread ensures a secure, leak-free pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50X20 Is Used
Short-Stroke Clamping
Ideal for securing workpieces in machining fixtures where a 20mm stroke provides rapid clamping and release without occupying excessive vertical space.
Gate Diverter
Delivers fast, high-force actuation for routing packages on conveyor lines, utilizing the 982N output to handle heavy product flows efficiently.
Ejector Station
Perfectly suited for compact ejection mechanisms in automated assembly, providing immediate impact force within a minimal machinery envelope.
Is the Airtac SAI50 Standard Cylinder SAI50X20 the Right Cylinder?
Choose the SAI50X20 when an application demands high force within a very tight linear footprint. If your mechanism requires less energy, stepping down to the 40mm bore yields 628N at 0.5MPa, whereas moving up to the 63mm bore provides 1559N for heavier loads. Because the 20mm stroke is short, side-load stress on the rod bearing is minimal compared to longer strokes.
As a true ISO 15552 profile cylinder, this unit serves as a direct replacement for any standard ISO 15552 interface, matching the 50mm bore, 20mm stroke, PT port, and standard mounting accessories like FA flanges or LB foot brackets. Note that the standard SAI does not hold loads when air pressure is exhausted; for position holding, explore the SAIL locking variant.
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.
