About the Airtac SAI100 Standard Air Cylinder SAI100X950S
The AirTAC SAI100X950-S is a double-acting ISO 15552 profile cylinder engineered for substantial actuation tasks, providing a push force of 3927 N at 0.5 MPa. This 100 mm bore unit features a 950 mm stroke, placing it near the upper limit of the standard maximum stroke range of 1500 mm. The extruded aluminum barrel design omits tie-rods, yielding a cleaner exterior that simplifies the mounting of accessories and switch tracks.
Equipped with a magnet for sensor integration, this model supports CMSE and DMSE switches seated in the dual side grooves. The standard carbon steel piston rod handles rigorous industrial demands, while the adjustable air cushions at both ends decelerate the heavy 100 mm piston smoothly. Operating speed spans 30-800 mm/s, making it a highly capable drop-in replacement for any ISO 15552 dimensionally interchangeable cylinder.

Where the Airtac SAI100 Standard Air Cylinder SAI100X950S Is Used
Large Press Handling
Lifts and positions heavy sheet metal blanks into large forming presses using the 3927 N push force available at 0.5 MPa.
Pallet Diversion
Actuates large-scale diverters on heavy-duty conveyor lines, utilizing the 950 mm stroke to clear wide pallet traffic.
Automated Assembly Lifts
Raises and lowers heavy subassembly platforms, relying on the integrated magnet and CMSE switches for precise end-position verification.
Is the Airtac SAI100 Standard Air Cylinder SAI100X950S the Right Cylinder?
Selecting this 100 mm bore is ideal when 80 mm falls short—yielding 2513 N at 0.5 MPa—or when 125 mm is excessively large. Because this 950 mm stroke creates a long unsupported rod extension, side-load forces can severely bend the rod bearing and cause premature seal wear. Implement an external guide rail or choose a fully guided cylinder to absorb lateral loads and prevent mechanical binding.
If your machinery loses pneumatic pressure, this standard SAI cylinder cannot hold its load and the rod will drift. For vertical applications requiring fail-safe positioning, integrate an external pilot-operated check valve or specify the SAIL variant with an air-released lock. This configuration uses PT tapered ports, a G1/2 thread size, and pairs with FA, LB, or TC mounting accessories.

- ✓ 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 SAI100X950S FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder generates a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X950-S is dimensionally interchangeable per ISO 15552. It shares the same mounting interface, G1/2 port size, and M20x1.5 rod thread as other standard profile cylinders, allowing for a direct drop-in replacement.
