About the Airtac SAI100 Standard Air Cylinder SAI100X450
The AirTAC SAI100X450 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for moving substantial masses across its 450 mm stroke. The extruded aluminum barrel design omits tie-rods, offering a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This configuration features a standard carbon steel piston rod and PT tapered port threads. For environments requiring position feedback, the barrel includes dual sensor grooves compatible with CMSE or DMSE switches when a magnet (-S) is specified. The standard TPU seals handle ambient temperatures from -20 to +70 C, while a Viton (H) seal option is available for elevated thermal demands.

Where the Airtac SAI100 Standard Air Cylinder SAI100X450 Is Used
Heavy Stamping
Provides the 3927 N push force required to actuate large mechanical stamping presses and forming dies at 0.5 MPa.
Pallet Diverting
Uses the 450 mm stroke to push heavy product pallets smoothly across high-throughput material handling lines.
Injection Molding
Extracts large molded parts from injection molding machines, utilizing the robust 100 mm bore to overcome ejection resistance.
Is the Airtac SAI100 Standard Air Cylinder SAI100X450 the Right Cylinder?
Selecting this 100 mm bore is ideal when 80 mm cylinders lack sufficient thrust. Stepping up from an 80 mm bore increases your 0.5 MPa push force from 2513 N to 3927 N, providing the extra power needed for high-inertia loads. Conversely, if your application only requires 2513 N, dropping to an 80 mm bore can save space and air consumption.
At a 450 mm stroke, the unsupported piston rod is susceptible to bending under side loads. Use external guide rails or a guided cylinder to prevent rod-bearing damage. Note that the adjustable air cushions at both ends decelerate the piston but do not lock the load; if pressure is lost, the rod will drift. Use a SAIL or BSAI variant if dead-load holding is required.
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 SAI100X450 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. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes. As a true ISO 15552 profile cylinder, the SAI100X450 is dimensionally interchangeable with other ISO 15552 cylinders. You can swap it into existing mounts using standard FA, FB, or TC accessories without modifying the machine frame.
