About the Airtac SAI50 Standard Cylinder SAI50X75
The AirTAC SAI50X75 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its extruded aluminum barrel eliminates tie-rods, providing a smooth exterior that drops directly into standardized ISO 15552 mounting footprints.
This 50 mm bore, 75 mm stroke configuration is built for compact, high-cycle tasks. It features a standard carbon steel piston rod and PT tapered port threads. Because a magnet is not specified, this base variant omits the integrated magnetic ring for position sensing.

Where the Airtac SAI50 Standard Cylinder SAI50X75 Is Used
Component Clamping
Provides reliable 982 N clamping force at 0.5 MPa for securing mid-sized metal parts during machining operations.
Package Diverting
Drives short-stroke diverting arms on packaging lines, offering fast actuation within a standardized ISO 15552 footprint.
Material Ejection
Ejects molded or stamped products from machinery, utilizing the 75 mm stroke for quick and compact part removal.
Is the Airtac SAI50 Standard Cylinder SAI50X75 the Right Cylinder?
Select this 50 mm bore when an application requires more power than a 40 mm cylinder (528 N pull at 0.5 MPa) but lacks the physical space for a 63 mm unit. The 75 mm stroke is optimal for short, rapid movements. For exact dimensional replacements, match the 50 mm bore, 75 mm stroke, PT G1/4 ports, and desired mounting accessories like FA flanges or TC trunnions.
Remember that standard air cushions only decelerate the piston near the end of the stroke; they do not hold a load. If your system loses pneumatic pressure, the rod will drift. Use an external pilot-operated check valve or the SAIL variant for fail-safe position holding.
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 SAI50X75 FAQ
At an operating pressure of 0.5 MPa, the SAI50X75 generates a push force of 982 N and a pull force of 825 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes, the SAI50X75 is dimensionally interchangeable per ISO 15552. You can drop it into existing setups by matching the 50 mm bore, 75 mm stroke, and G1/4 port size, but ensure your mounting accessories align.
