About the Airtac SAI125 Standard Air Cylinder SAI125AX160S
The AirTAC SAI125X160-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 6136 N of push force at 0.5 MPa, this 125 mm bore unit is built to drive demanding industrial loads. The 160 mm stroke provides ample extension for clamping, lifting, and press operations. As a genuine AirTAC component, it guarantees reliable performance in high-cycle environments.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A), providing superior corrosion resistance compared to standard carbon steel. The integrated magnet (-S) enables direct mounting of CMSE or DMSE series solid-state switches along the extruded aluminum barrel's dual sensor grooves, streamming position feedback integration. Fluid ports feature PT tapered threading for a secure, leak-free pneumatic connection.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX160S Is Used
Heavy-Duty Pressing
Generates 8590 N of thrust at 0.7 MPa, making it ideal for pressing bearings, bushings, and forming small metal components securely.
Automotive Component Handling
Provides the robust actuation force necessary for moving heavy chassis parts or positioning engine blocks along high-throughput assembly lines.
Pallet Diverting
Exerts high lateral force to shift heavy loaded pallets between adjacent conveyor lanes in demanding material handling systems.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX160S the Right Cylinder?
When evaluating this 125 mm bore option, consider stepping down to the 80 mm bore if your application requires less than 2268 N of pull force at 0.5 MPa, which saves valuable machine space and air consumption. Conversely, if your load demands exceed 10053 N at 0.5 MPa, upgrading to the 160 mm bore variant is the recommended path. The 160 mm stroke here is well-suited for standard actuation without requiring extensive overhang.
For applications involving heavy vertical loads or those that must maintain position during a complete loss of supply pressure, remember that the standard adjustable air cushions at both ends only decelerate the piston near stroke termination; they do not function as a mechanical brake. If true holding force is required without live air pressure, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead. Being a true ISO 15552 profile cylinder, it serves as a seamless, dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders, utilizing standard FA/FB flanges or CA/CB clevis 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 SAI125 Standard Air Cylinder SAI125AX160S FAQ
At a 0.5 MPa operating pressure, the SAI125X160-S provides 6136 N of push force and 5734 N of pull force. If operating pressure is increased to 0.7 MPa, the push force reaches 8590 N.
Yes. The SAI125X160-S features a standardized ISO 15552 mounting interface, meaning it is dimensionally interchangeable with other ISO 15552 profile cylinders and accepts standard FA, FB, CA, and CB mounting accessories.
