About the Airtac SAI100 Standard Air Cylinder SAI100X135FTC
The AirTAC SAI100X135 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 actuator provides the thrust required for demanding industrial tasks. The 135 mm stroke offers precise linear movement within a compact footprint.
This model features a standard carbon steel piston rod and utilizes PT tapered port threads for secure pneumatic connections. The extruded aluminum barrel incorporates dual sensor grooves, allowing for straightforward position feedback when paired with compatible switches. Adjustable air cushions at both ends ensure smooth deceleration of large loads.

Where the Airtac SAI100 Standard Air Cylinder SAI100X135FTC Is Used
Heavy-Duty Stamping
Provides the 3927 N push force at 0.5 MPa needed to operate mechanical stamping and forming presses reliably.
Pallet Diverting
Delivers robust lateral force to redirect heavy loaded pallets along high-throughput material handling conveyors.
Industrial Pressing
Ideal for applying consistent downward pressure in automated assembly lines for bearing and bushing insertion.
Is the Airtac SAI100 Standard Air Cylinder SAI100X135FTC the Right Cylinder?
Select this 100 mm bore when an 80 mm cylinder (providing 2513 N at 0.5 MPa) lacks the necessary thrust for your application. If your system requires less force, stepping down reduces air consumption. The 135 mm stroke is well within standard limits, so side-load stress on the rod bearing is minimal compared to longer extensions.
This variant is configured with an FTC trunnion mounting accessory and PT tapered ports. It does not include a magnet. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders for seamless drop-in replacement. Note that a standard SAI does not hold its position if air pressure is lost; use the SAIL lock variant for fail-safe load holding.
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 SAI100X135FTC FAQ
