About the Airtac SAI125 Standard Air Cylinder SAI125AX60S
The AirTAC SAI125X60-S is a double-acting ISO 15552 profile cylinder engineered for high-force tasks. It supplies 6136 N of push force at 0.5 MPa, making it well-suited for heavy-duty clamping and pressing over its 60 mm stroke.
This variant includes a SUS420J2 stainless steel rod for superior corrosion resistance and a pre-installed magnet for CMSE or DMSE sensor switches. The extruded aluminum barrel features dual sensor grooves, and fluid ports use PT tapered threading.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX60S Is Used
Heavy-Duty Stamping
Provides the robust 6136 N force needed to seat bearings or stamp thick metal components securely.
Industrial Clamping
Holds large molds or heavy workpieces firmly in place during aggressive machining operations.
Pallet Handling
Generates high push force to lift, shift, or position fully loaded pallets in automated logistics.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX60S the Right Cylinder?
Choose this 125 mm bore when 80 mm (2513 N at 0.5 MPa) lacks the power for heavy lifting, but you want to avoid the larger 160 mm frame. The 60 mm stroke is optimal for short, powerful movements.
Because a standard SAI relies on live air pressure to maintain its position, the piston will drift if air is lost or the valve centers. For safety-critical loads that require holding without pressure, select the SAIL or BSAI locking variants. As a true ISO 15552 profile cylinder, it drops in seamlessly with other ISO 15552 mounts using TC, CA, or LB accessories.

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.
