About the Airtac SAI100 Standard Air Cylinder SAI100BX50S
The AirTAC SAI100X50-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning. It delivers a robust 3927 N of push force at 0.5 MPa, making it well-suited for short 50 mm clamping and lifting cycles. The extruded aluminum barrel omits tie-rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet (-S). The magnet enables seamless integration with CMSE or DMSE sensor switches, which seat directly into the dual grooves machined on both sides of the barrel. Fluid compatibility is limited to filtered air, operating efficiently between 30-800 mm/s.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX50S Is Used
Heavy-Duty Stamping
Provides the 3927 N push force at 0.5 MPa needed to seat bearings or form thick materials over a 50 mm travel distance.
Pallet Clamping
Secures heavy pallets or fixtures in automated storage systems, using the integrated magnet to confirm clamp position.
Press Ejection
Ejects dense metal or composite parts from press beds quickly, utilizing the SUS304 rod to withstand harsh industrial environments.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX50S the Right Cylinder?
Selecting this 100 mm bore is ideal when 80 mm (2513 N at 0.5 MPa) lacks the necessary thrust for heavy payloads, but you want to avoid the added mass of a 125 mm unit. The 50 mm stroke excels at short, high-force transfer tasks. Because the stroke is brief, rod-bearing side-load bending is minimal compared to longer extensions.
This model features PT tapered port threads and operates as a standard double-acting actuator. It does not hold its load if air pressure is removed; the piston will drift. For applications requiring dead-stop holding without live pressure, specify the SAIL or BSAI locking variants. To guarantee a true ISO 15552 replacement match, verify the 100 mm bore, 50 mm stroke, G1/2 port, and your required mounting accessory (such as FA flange or TC trunnion).
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 SAI100 Standard Air Cylinder SAI100BX50S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If pressure increases to 0.7 MPa, the push force rises to 5497 N.
Yes. The SAI100X50-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts matching the 100 mm bore, 50 mm stroke, and G1/2 port, provided you use compatible mounting accessories.
