About the Airtac SAI125 Standard Air Cylinder SAI125X60S
The AirTAC SAI125X60-S is a double-acting ISO 15552 profile cylinder engineered for high-force tasks, delivering a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. Its 60 mm stroke is optimal for short, powerful clamping or pressing operations.
This variant includes a magnetic piston for position sensing with CMSE or DMSE switches, which mount directly into the dual sensor grooves on the extruded aluminum barrel. The standard carbon steel piston rod provides robust durability, while the adjustable air cushions at both ends ensure smooth deceleration within its 30-500 mm/s speed range.

Where the Airtac SAI125 Standard Air Cylinder SAI125X60S Is Used
Heavy-Duty Stamping
Provides the robust 6136 N thrust required for short-stroke metal stamping and forming operations.
Industrial Clamping
Ideal for securing heavy workpieces during machining, utilizing its 125 mm bore for immovable holding force.
Press Assembly
Drives heavy-duty press operations where a short 60 mm stroke and high impact force are essential.
Is the Airtac SAI125 Standard Air Cylinder SAI125X60S the Right Cylinder?
Select this 125 mm bore when 100 mm (3927 N push at 0.5 MPa) lacks the necessary thrust for heavy pressing, but you want to avoid the larger 160 mm frame. Because the stroke is only 60 mm, rod-bearing bending is negligible, but always ensure the load is axially aligned to prevent side-load wear.
This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders. It features a PT tapered G1/2 port, supports various mounting accessories like TC trunnion or FA flange, and its -S magnet enables precise end-of-stroke detection.
