About the Airtac SAI50 Standard Cylinder SAI50AX15S
The AirTAC SAI50X15-S is a double-acting ISO 15552 profile cylinder engineered for short-stroke actuation. It provides a robust push force of 982 N at 0.5 MPa, making it well-suited for compact clamping and ejection tasks. The extruded aluminum barrel design eliminates traditional tie rods while maintaining strict dimensional interchangeability with other ISO 15552 actuators.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid or mildly chemically washed environments. Equipped with a magnetic piston (-S), it seamlessly integrates CMSE or DMSE sensor switches via the dual side grooves on the barrel for precise end-of-stroke detection.

Where the Airtac SAI50 Standard Cylinder SAI50AX15S Is Used
Short-Stroke Clamping
Ideal for holding workpieces securely in machining fixtures where a brief 15 mm movement and 982 N of force at 0.5 MPa are required.
Package Ejection
Provides rapid, compact ejection of items from conveyor lines using its 825 N pull force at 0.5 MPa and dual adjustable cushions.
Gate Diverter
Actuates short diverter gates on packaging machinery, benefiting from the SUS420J2 stainless steel rod in washdown areas.
Is the Airtac SAI50 Standard Cylinder SAI50AX15S the Right Cylinder?
Selecting this 50 mm bore is optimal when a 40 mm bore (628 N at 0.5 MPa) lacks the necessary thrust, but a 63 mm bore (1559 N at 0.5 MPa) is physically oversized. The 15 mm stroke is non-standard but highly effective for space-constrained mechanisms. Because the stroke is short, side-load stress on the rod bearing is minimal compared to longer strokes. However, if your application requires the load to remain mechanically fixed upon air pressure loss, note that the standard adjustable air cushions only decelerate the piston at stroke end and do not function as a lock. For secure holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This model uses PT tapered ports and supports standard ISO 15552 mounting accessories like FA 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 SAI50AX15S FAQ
At 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. If pressure is increased to 0.7 MPa, the push force reaches 1374 N.
Yes, the SAI50X15-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 standard cylinders of the same bore size.
