About the Airtac SAI100 Standard Air Cylinder SAI100AX140S
The AirTAC SAI100X140-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 5497 N push force at 0.7 MPa, this 100mm bore unit is built to handle substantial loads across its 140mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies sensor mounting and machine integration.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid or mildly chemically washed environments. Equipped with a magnet (-S), it seamlessly interfaces with CMSE and DMSE series reed switches fitted into the dual-side sensor grooves. Standard adjustable air cushions at both ends ensure smooth deceleration of heavy payloads.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX140S Is Used
Heavy Material Handling
Ideal for lifting and transferring heavy pallets or metal sheets where the 5497 N push force at 0.7 MPa easily manages substantial dead weights.
Pressing and Stamping
Provides consistent, high-force pressing action for light assembly tasks, bearing insertion, or metal forming operations within a compact 140mm stroke.
High-Capacity Diverting
Suitable for actuating heavy-duty diverter arms or sorting gates on high-throughput conveyor lines, utilizing the adjustable cushions to cushion stop impacts.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX140S the Right Cylinder?
Choosing this 100mm bore is ideal when 80mm cylinders (providing 3518 N push at 0.5 MPa) lack the necessary thrust for high-inertia loads. If your application requires less force and faster cycling, stepping down to an 80mm bore optimizes air consumption. Because the SAI100X140-S is a double-acting actuator, it cannot hold a load in place if air pressure drops completely; for fail-safe load holding, consider the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 profile cylinders without requiring custom mounting plates. To complete your setup, pair this 140mm stroke unit with PT threaded ports, FA/FB flanges or TC trunnion brackets, and CMSE/DMSE sensors to utilize the built-in magnet.

- ✓ 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.
