About the Airtac SAI100 Standard Air Cylinder SAI100X145S
The AirTAC SAI100X145-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100 mm bore unit is built to handle substantial loads across its 145 mm stroke. The extruded aluminum barrel design eliminates tie-rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
Equipped with a magnetic piston (-S), this model seamlessly integrates with CMSE and DMSE reed switches via the dual sensor grooves machined into both sides of the barrel. The standard carbon steel piston rod provides excellent tensile strength for industrial applications, while the adjustable air cushions at both ends ensure smooth deceleration of heavy moving masses.

Where the Airtac SAI100 Standard Air Cylinder SAI100X145S Is Used
Heavy Stamping
Provides the 3927 N push force required to actuate large pressing and stamping dies in metal fabrication lines.
Pallet Handling
Drives robust lifting and positioning mechanisms for heavy-loaded pallets in automated distribution hubs.
Plastic Injection
Operates large mold clamping and ejection arms on injection molding machinery requiring reliable magnetic position feedback.
Is the Airtac SAI100 Standard Air Cylinder SAI100X145S the Right Cylinder?
Selecting this 100 mm bore is ideal when a 80 mm bore (providing 2513 N push at 0.5 MPa) lacks the necessary thrust, but you want to avoid the larger physical envelope of a 125 mm cylinder. The 145 mm stroke offers a compact extension length, keeping the unsupported rod highly rigid and minimizing side-load bending concerns. For ISO 15552 drop-in replacements, match the 100 mm bore, 145 mm stroke, PT G1/2 port, and your required mounting accessory (such as FA flange or TC trunnion). If your mechanism must maintain vertical position after air pressure is removed, a standard SAI will drift downward; you must specify the SAIL variant with an air-released lock or utilize an external pilot check valve.
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 SAI100X145S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X145-S is dimensionally interchangeable per ISO 15552. You can drop it into existing ISO 15552 mounting interfaces, matching the G1/2 port and 100 mm bore dimensions.
