About the Airtac SAI100 Standard Air Cylinder SAI100AX145S
The AirTAC SAI100X145-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for high-thrust pressing and heavy load manipulation. The 145 mm stroke offers precise mid-range travel for compact machinery.
This variant includes a built-in magnet for position sensing and uses a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. The extruded aluminum barrel features sensor grooves on both sides for direct mounting of CMSE or DMSE switches. Fluid porting utilizes PT tapered threads, and the cylinder incorporates adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX145S Is Used
Heavy-Duty Pressing
Generates 5497 N of thrust at 0.7 MPa for assembling bearings and riveting metal components in automated fabrication cells.
Large Part Ejection
Uses the 145 mm stroke and 3681 N pull force at 0.5 MPa to positively eject heavy molded parts from machining centers.
Pallet Diverting
Handles robust side-loading tasks on conveyor lines, moving heavy pallets with reliable double-acting power.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX145S the Right Cylinder?
Select this 100 mm bore model when an application demands upward of 3900 N of push force at 0.5 MPa, or step down to the 80 mm bore if 2513 N is sufficient for lighter duty. The 145 mm stroke keeps the rod fully supported without excessive overhang, minimizing bearing wear.
As a true ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders. To match this exact configuration, specify the 100 mm bore, 145 mm stroke, G1/2 port, PT thread, and the -S magnet option. Note that this standard cylinder relies on live air pressure to move; it will not hold a load if air is lost. For dead-end holding, consider the SAIL or BSAI variants.
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 SAI100AX145S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes. It is built to the ISO 15552 standard, meaning its mounting dimensions are interchangeable with other ISO 15552 profile cylinders of the same bore size.
