About the Airtac SAI125 Standard Air Cylinder SAI125X110
The AirTAC SAI125X110 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a robust push force of 6136 N at 0.5 MPa, making this 125mm bore variant ideal for high-thrust pressing and heavy load manipulation. The 110mm stroke provides substantial extension for substantial workpiece handling. This extruded aluminum barrel design eliminates exposed tie-rods, offering a cleaner exterior that resists mechanical damage and contamination.
Built for demanding environments, this specific configuration features a standard carbon steel piston rod and PT tapered port threads for secure, leak-free pneumatic connections. While the standard seal compound handles most industrial temperatures, users can specify Viton (H) or NBR (N) elastomers for specialized thermal or chemical exposures. For applications requiring multi-directional clamping or locking without sustained air pressure, the related BSAI bidirectional clamp-lock series offers a robust alternative.

Where the Airtac SAI125 Standard Air Cylinder SAI125X110 Is Used
Heavy-Duty Stamping
Provides the 6136 N push force required for deforming or stamping rigid materials in automated fabrication cells.
Pallet Diversion
Handles heavy pallets on high-mass conveyor lines, using the 110mm stroke to push loads firmly onto transfer rails.
Injection Molding Extraction
Delivers the raw extraction power needed to pull heavy molded parts from industrial presses.
Is the Airtac SAI125 Standard Air Cylinder SAI125X110 the Right Cylinder?
Select this 125mm bore when your application requires forces around 6136 N at 0.5 MPa. If your load requirements are lower, stepping down to the 100mm bore (which provides 3927 N at 0.5 MPa) can optimize air consumption and cycle speed. Conversely, if higher thrust is needed, the 160mm bore outputs 10053 N. The 110mm stroke is well within standard limits, keeping the rod bearing under minimal deflection stress.
As a true ISO 15552 profile cylinder, the SAI125X110 is dimensionally interchangeable with other ISO 15552 cylinders, ensuring a seamless drop-in replacement for existing setups. It uses G1/2 ports and can be paired with standard mounting accessories like FA flanges or TC trunnions. Note that a standard SAI does not hold position when air pressure is lost; if dead-load holding is required, consider the SAIL (air-released lock) variant or an external pilot-operated check valve. To add proximity sensing, specify the -S magnet option for use with CMSE or DMSE sensors in the dual barrel grooves.

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.
