About the Airtac SAI100 Standard Air Cylinder SAI100X145
The AirTAC SAI100X145 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 145mm stroke. It delivers a push force of 3927N at 0.5MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel eliminates traditional tie-rods while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
Equipped with a standard carbon steel piston rod, this model uses a PT tapered port thread. If your assembly line requires position feedback, you can specify the -S magnet option to utilize CMSE or DMSE sensors in the dual lateral grooves.

Where the Airtac SAI100 Standard Air Cylinder SAI100X145 Is Used
Automotive Body Welding
Handles heavy clamping guns and fixture movements on automotive assembly lines, utilizing its 3927N push force to secure heavy steel panels.
Pallet Diverting
Actuates heavy-duty diverter arms on high-throughput packaging conveyors, moving fully loaded pallets with reliable ISO 15552 precision.
Injection Mold Ejection
Drives robust ejection mechanisms for large plastic injection molds, where the 145mm stroke provides the exact clearance needed for part removal.
Is the Airtac SAI100 Standard Air Cylinder SAI100X145 the Right Cylinder?
If 3927N is excessive for your payload, stepping down to the 80mm bore yields 2513N at 0.5MPa, whereas moving up to the 125mm bore provides 6136N. Because the 145mm stroke is relatively short, standard rod-bearing bending is minimal, though external guides are always recommended for rigidly mounted loads.
Remember that the adjustable air cushions at both ends only decelerate the piston near stroke limits; they do not function as a brake. If the system must hold a vertical load when air pressure is lost, integrate the SAIL variant or an external pilot-operated 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 SAI100X145 FAQ
At 0.5MPa operating pressure, the push force is 3927N and the pull force is 3681N. If you increase the pressure to 0.7MPa, the push force reaches 5497N.
Yes, the SAI100X145 is a true ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 standard cylinders of the same bore size.
