About the Airtac SAI50 Standard Cylinder SAI50BX15
The AirTAC SAI50X15 is a double-acting ISO 15552 profile cylinder engineered for short-stroke actuation. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it highly effective for compact pressing and clamping tasks. The 15 mm stroke provides rapid, precise end-to-end movement without consuming excessive machine footprint.
Built to exacting standards, this specific configuration utilizes a SUS304 stainless steel rod for superior corrosion resistance in washdown or chemically exposed environments. It features PT tapered port threads and an extruded aluminum barrel with dual sensor grooves, allowing for flexible CMSE or DMSE switch mounting when a magnet is specified separately.

Where the Airtac SAI50 Standard Cylinder SAI50BX15 Is Used
Short-Stroke Clamping
Ideal for securing lightweight components during machining or assembly, using its 982 N push force to hold parts firmly in place over a 15 mm travel distance.
Product Ejection
Provides rapid, compact ejection of finished goods from conveyor lines, where a short 15 mm stroke is sufficient to push items clear of the production path.
Spot Welding Positioning
Moves welding electrodes into precise contact with a workpiece, leveraging the SUS304 rod for durability in high-heat, spark-heavy industrial environments.
Is the Airtac SAI50 Standard Cylinder SAI50BX15 the Right Cylinder?
Select this 50 mm bore when an application requires more power than a 40 mm cylinder (628 N at 0.5 MPa) but lacks the physical space for a 63 mm unit (1559 N at 0.5 MPa). The 15 mm stroke is optimal for high-cycle clamping or ejecting where only a few millimeters of travel are necessary. Because the stroke is very short, rod-bearing bending is minimal, and external guides are rarely required for side loads.
This model is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 cylinders with matching 50 mm bore, 15 mm stroke, G1/4 port, and standard mounting accessories like FA or LB. Note that a standard SAI cylinder relies on continuous air pressure to maintain its position; if air is lost, the piston will drift. For dead-end holding without live pressure, consider the SAIL variant or an external pilot check valve.
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 SAI50BX15 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides a push force of 982 N and a pull force of 825 N. If you increase the pressure to 0.7 MPa, the push force rises to 1374 N.
Yes. As a genuine ISO 15552 profile cylinder, the SAI50X15 is dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke, matching standard mounting interfaces and G1/4 port sizes.
