About the Airtac SAI100 Standard Air Cylinder SAI100AX140
The AirTAC SAI100X140 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 5497 N at 0.7 MPa, making it well-suited for high-load pressing and clamping operations over its 140 mm stroke. The extruded aluminum barrel design omits traditional tie rods, offering a clean exterior that resists mechanical interference.
This specific configuration features a SUS420J2 stainless steel rod for superior corrosion resistance and reduced wear in harsh environments. It utilizes PT tapered port threads for a reliable, mechanically sealed pneumatic connection. The barrel includes integrated sensor grooves on both sides, allowing for straightforward position feedback when paired with compatible reed or solid-state switches.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX140 Is Used
Heavy-Duty Stamping
Provides the necessary 5497 N output force at 0.7 MPa to deform metal sheets or securely hold large workpieces during aggressive machining operations.
Pallet Diversion
Generates enough push power to reliably redirect heavy loaded pallets along high-throughput material handling conveyor lines without stalling.
Automated Pressing
Executes 140 mm stroke pressing cycles for bearing insertion or component seating tasks requiring consistent, high-thrust linear motion.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX140 the Right Cylinder?
Selecting this 100 mm bore is ideal when applications demand upward of 5000 N of thrust; stepping down to an 80 mm bore yields 3518 N at 0.7 MPa, which may be insufficient for heavy moving masses. For this 140 mm stroke, side-load stress on the rod bearing is minimal, though external guides are always recommended if the load geometry is offset. Because this is a standard double-acting cylinder, it will not maintain its position if air pressure is lost; applications requiring mid-stroke holding or fail-safe locking must integrate an external pilot-operated check valve or select the BSAI clamp-lock variant. This model ensures seamless dimensional interchangeability with other ISO 15552 cylinders, using a G1/2 port, an M20x1.5 rod thread, and compatibility with FA/FB flange or TC trunnion mounting accessories.

- ✓ 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.
