About the Airtac SAI100 Standard Air Cylinder SAI100AX135S
The AirTAC SAI100X135-S is a double-acting ISO 15552 profile cylinder offering a robust 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa. This 135 mm stroke length is well suited for medium-duty positioning tasks requiring substantial thrust. The extruded aluminum barrel design omits tie rods for a clean exterior.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. The -S suffix denotes an integrated magnet, allowing direct mounting of CMSE or DMSE reed switches along the dual sensor grooves machined into both sides of the barrel.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX135S Is Used
Heavy-Duty Stamping
Provides the 5497 N push force at 0.7 MPa required to actuate medium-tonnage stamping and forming presses.
Pallet Diverter
Uses the 135 mm stroke to push heavy pallets onto secondary conveyor lines, utilizing the integrated magnet for end-of-stroke confirmation.
Automated Clamping
Secures large workpieces during machining operations, taking advantage of the 36 mm adjustable cushioning to stop heavy masses smoothly.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX135S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant (2513 N push at 0.5 MPa) is necessary when your application demands upward of 3900 N of thrust at 0.5 MPa. If you need significantly less force, stepping down to the 80 mm bore saves space and air consumption. The 135 mm stroke falls below the 300 mm threshold, so standard rod-bearing bending is minimal, though side loads should still be minimized.
As a standard double-acting actuator, this cylinder relies on live air pressure to hold its position; if air is exhausted or the valve is centered, the piston will drift. For applications requiring true load holding without continuous pressure, consider the SAIL (pneumatic lock) or BSAI (clamp-lock) variants. To replace an existing actuator, match the 100 mm bore, 135 mm stroke, PT G1/2 port thread, and ISO 15552 mounting accessories like FA flanges or TC trunnions.
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 SAI100AX135S FAQ
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X135-S is dimensionally interchangeable per ISO 15552 mounting interface dimensions. You can replace other ISO 15552 profile cylinders by matching the 100 mm bore, 135 mm stroke, and G1/2 port size.
