About the Airtac SAI50 Standard Cylinder SAI50BX5S
The AirTAC SAI50X5-S is a double-acting ISO 15552 profile cylinder engineered for ultra-short 5mm strokes, delivering 982N of push force at 0.5 MPa. Its extruded aluminum barrel omits tie rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
Configured with a SUS304 stainless steel rod for superior corrosion resistance, this specific model includes an internal magnet for non-contact position sensing. You can mount CMSE or DMSE switches directly into the dual sensor grooves molded into the barrel sides.

Where the Airtac SAI50 Standard Cylinder SAI50BX5S Is Used
Short-Stroke Clamping
Ideal for tightly spaced production lines where a 5mm stroke securely clamps machined parts without consuming excessive footprint.
Valve Actuation
Provides the rapid, precise linear push required to trip process valves or trigger mechanical latches in confined machinery.
Ejector Mechanisms
Delivers a fast 982N punch at 0.5 MPa to eject small finished components from molding or machining fixtures instantly.
Is the Airtac SAI50 Standard Cylinder SAI50BX5S the Right Cylinder?
Choose this 50mm bore when a 32mm bore falls short—its 402N push force at 0.5 MPa is less than half the capacity of this 50mm unit. If your assembly requires even more power, stepping up to the 63mm bore yields 1559N. Because the 5mm stroke is so brief, side-load stress on the rod bearing is minimal compared to longer extensions.
Remember that the adjustable air cushions at both ends decelerate the piston near stroke end but do not lock the load. If pressure drops, the rod drifts; for fail-safe holding, select the SAIL variant or install an external pilot-operated check valve. This -S configuration uses PT tapered ports and accepts standard FA/FB flanges or LB foot brackets.
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 SAI50BX5S FAQ
