About the Airtac SAI100 Standard Air Cylinder SAI100X125S
The AirTAC SAI100X125-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 125mm stroke. It delivers a robust push force of 3927 N at 0.5 MPa, making it well-suited for heavy-duty handling and pressing tasks. The barrel is extruded aluminum without tie rods, offering a clean profile while maintaining standardized mounting dimensions.
This specific configuration includes a magnetic piston for use with CMSE and DMSE sensor switches, which ride neatly in the integrated grooves on both sides of the barrel. It utilizes a standard carbon steel piston rod and features PT tapered port threads. Adjustable air cushions at both ends ensure smooth deceleration of substantial moving loads at cycle speeds up to 30-800 mm/s.

Where the Airtac SAI100 Standard Air Cylinder SAI100X125S Is Used
Automotive Assembly
Provides the 3927 N push force required to seat heavy components and perform precision pressing operations on the line.
Material Forming
Delivers consistent clamping pressure for holding large metal or composite sheets during secondary machining processes.
Heavy Pallet Handling
Lifts and diverts substantial loaded pallets on packaging conveyors, utilizing adjustable cushions to absorb high kinetic energy.
Is the Airtac SAI100 Standard Air Cylinder SAI100X125S the Right Cylinder?
If 3927 N of push force is excessive for your application, consider stepping down to the 80mm bore variant, which provides 2513 N at 0.5 MPa. Conversely, moving up to the 125mm bore yields 6136 N for heavier demands. Because this is a standard 125mm stroke, side-load stress on the rod bearing is minimal compared to longer travel lengths.
This cylinder relies on continuous air pressure to move; it will not hold a load in place if air is exhausted. For applications requiring mechanical position holding upon pressure loss, select the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 100mm bore, 125mm stroke ISO 15552 unit, utilizing a PT G1/2 port and standard FA/FB flange or TC trunnion mounts.

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 SAI100X125S FAQ
At an operating pressure of 0.5 MPa, this 100mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes. The SAI100X125-S is manufactured to ISO 15552 dimensional standards, meaning it is fully interchangeable with other 100mm bore profile cylinders from various brands that follow the same ISO 15552 mounting interface.
