About the Airtac SAI125 Standard Air Cylinder SAI125BX60S
The AirTAC SAI125X60-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty handling. It provides a robust push force of 6136 N and a pull force of 5734 N at 0.5 MPa, making it well-suited for short, high-impact pressing and clamping operations.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance and includes an integrated magnet for position sensing. The extruded aluminum barrel includes sensor grooves on both sides, allowing direct mounting of CMSE or DMSE switches without additional brackets.

Where the Airtac SAI125 Standard Air Cylinder SAI125BX60S Is Used
Heavy-Duty Stamping
Executes short-stroke, high-force pressing tasks in automated assembly lines, utilizing its 6136 N push capability at 0.5 MPa.
Pallet Halting
Acts as a robust stopper for heavy material handling conveyors, with the SUS304 rod enduring harsh industrial environments.
Industrial Clamping
Secures large workpieces during machining or welding operations, relying on precise CMSE sensor feedback to confirm clamping position.
Is the Airtac SAI125 Standard Air Cylinder SAI125BX60S the Right Cylinder?
Choose this 125mm bore when 80mm bore cylinders (delivering 2513 N push at 0.5 MPa) cannot generate the required holding force. The 60mm stroke is optimal for compact, high-force movements. Because the standard SAI lacks a locking mechanism, loads will drift if air pressure is lost; use a SAIL variant or external pilot check valve for fail-safe position holding.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other standard profile cylinders. Match your mounting hardware using FA or FB flanges, TC trunnion, or LB foot brackets. Ensure your pneumatic plumbing matches the PT tapered G1/2 port.

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.
