About the Airtac SAI100 Standard Air Cylinder SAI100AX135
The AirTAC SAI100X135 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation, delivering a robust push force of 3927 N at 0.5 MPa. Its 135 mm stroke provides the exact travel needed for mid-length actuation tasks in high-demand machinery.
This genuine AirTAC unit features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance and reduced wear in humid environments. It utilizes PT tapered port threads for a reliable, leak-free connection, and its extruded aluminum barrel includes dual sensor grooves for direct CMSE or DMSE switch mounting.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX135 Is Used
Heavy Stamping
Provides the high thrust required for pressing bearings or forming metal components in automated production lines.
Pallet Diverting
Actuates heavy-duty routing gates to redirect large pallets along high-throughput material handling conveyors.
Plastic Molding Eject
Ejects dense plastic parts from heavy molds, utilizing the 135 mm stroke for rapid, forceful extraction.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX135 the Right Cylinder?
Choose this 100 mm bore when a 80 mm bore (2513 N push at 0.5 MPa) lacks the thrust for your heavier payloads, but a 125 mm cylinder (6136 N) would be excessive overkill. The 135 mm stroke is a non-standard intermediate length, making it ideal for applications requiring precise travel that falls between standard 125 mm and 150 mm options.
Because the 135 mm stroke is relatively short, side-load stress on the rod bearing is minimal compared to longer strokes. However, remember that a standard SAI relies on live air pressure to maintain its position; it will drift if supply is lost. For dead-end holding without air, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. To replace this unit, match the 100 mm bore, 135 mm stroke, PT G1/2 port, and desired mounting accessory.
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 SAI100AX135 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. At the maximum 1.0 MPa pressure, the theoretical push force reaches 801 kgf.
Yes, as a true ISO 15552 profile cylinder, its mounting interface dimensions are standardized. It serves as a drop-in replacement for other ISO 15552 cylinders, provided you match the 100 mm bore, 135 mm stroke, and G1/2 port size.
