About the Airtac SAI63 Standard Cylinder SAI63X950
The AirTAC SAI63X950 is a double-acting ISO 15552 profile cylinder engineered for demanding linear motion tasks. Operating at 0.15-1.0 MPa, it generates a push force of 1559 N at 0.5 MPa and 2182 N at 0.7 MPa. This specific configuration features a 950 mm stroke, making it a made-to-order non-standard length suited for extensive travel requirements.
Built with an extruded aluminum barrel, this unit omits the magnet option, meaning it is not directly compatible with CMSE or DMSE sensor switches unless modified. The standard carbon steel piston rod provides dependable structural integrity for industrial machinery. It features adjustable air cushions at both ends to manage kinetic energy, though the 950 mm stroke demands careful attention to lateral loading.

Where the Airtac SAI63 Standard Cylinder SAI63X950 Is Used
Extended Reach Pressing
Ideal for applying 1559 N of clamping force across a wide 950 mm stroke in automated assembly lines where parts are spaced far apart.
Long-Stroke Diverting
Perfect for pushing heavy pallets or components across wide conveyor belts, utilizing the full 950 mm travel distance for material routing.
High-Bay Ejection
Suitable for ejecting packaged goods from elevated storage tiers, taking advantage of the long stroke to clear structural obstructions safely.
Is the Airtac SAI63 Standard Cylinder SAI63X950 the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm bore yields a significant force jump, increasing from 982 N to 1559 N at 0.5 MPa. If your application requires even less force, stepping down to the 40 mm bore provides 628 N. Because this model features a 950 mm stroke, the unsupported rod length is substantial; side loads will cause bending stress on the rod bearing. For optimal longevity, pair this cylinder with an external guide rail or utilize a fully guided cylinder to prevent premature wear.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders such as SMC or Festo equivalents. This specific unit uses a PT tapered G3/8 port and standard carbon steel rod material. Remember that the adjustable cushion only decelerates the piston near stroke end; if your machinery must hold a load vertically without continuous air pressure, integrate the SAIL locking variant or an external rod 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 SAI63 Standard Cylinder SAI63X950 FAQ
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. If you increase the operating pressure to 0.7 MPa, the push force reaches 2182 N.
Yes, the SAI63X950 is a genuine ISO 15552 profile cylinder. Its standardized mounting interface makes it dimensionally interchangeable with other ISO 15552 profile cylinders, provided you match the 63 mm bore and 950 mm stroke.
