About the Airtac SAI50 Standard Cylinder SAI50BX950
The AirTAC SAI50X950 is a double-acting ISO 15552 profile cylinder engineered for a 950mm stroke, generating 982N of push force at 0.5MPa. Because 950mm exceeds the standard maximum stroke of 1200mm for this bore, it is manufactured as a made-to-order non-standard stroke to meet your specific linear motion requirements.
This genuine AirTAC unit features a SUS304 stainless steel rod for superior corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing for straightforward position monitoring when paired with CMSE or DMSE switches.

Where the Airtac SAI50 Standard Cylinder SAI50BX950 Is Used
Long-Reach Material Handling
Drives extended pusher mechanisms on conveyor lines where a 950mm travel distance is required to transfer products between workstations.
Automated Assembly Extraction
Extracts long components or sub-assemblies from machinery, utilizing the 982N push force to reliably pull parts free of tooling fixtures.
Palletizing Discharge
Acts as a long-stroke diverter or discharge actuator in packaging zones, moving goods clear of automated palletizing robotic cells.
Is the Airtac SAI50 Standard Cylinder SAI50BX950 the Right Cylinder?
This 50mm bore provides 982N push force at 0.5MPa; step down to a 40mm bore (628N) for lighter loads or up to a 63mm bore (1559N) if you need higher thrust. At 950mm of stroke, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature wear on the rod-bearing, implement an external guide rail or utilize a guided cylinder to handle any lateral forces.
As a true ISO 15552 profile cylinder, it offers a direct replacement for any matching 50mm bore, 950mm stroke, G1/4 port interface with standard mounting accessories like FA/FB flanges or TC trunnions. Note that the adjustable air cushions only decelerate the piston near stroke ends; they do not lock the load. If your application requires position holding without live air pressure, consider the SAIL variant with an air-released lock.
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 SAI50BX950 FAQ
At a 0.5MPa operating pressure, the SAI50X950 provides 982N of push force and 825N of pull force. At 0.7MPa, the push force increases to 1374N.
Yes, the SAI50X950 is a dimensionally interchangeable ISO 15552 profile cylinder. It serves as a direct replacement for other ISO 15552 cylinders with matching 50mm bore, 950mm stroke, and G1/4 port dimensions.
