About the Airtac SAI125 Standard Air Cylinder SAI125AX10S
The AirTAC SAI125X10-S is a double-acting ISO 15552 profile cylinder engineered for high-force, short-stroke execution. Delivering a robust 6136 N of push force at 0.5 MPa, it is purpose-built for heavy-duty clamping and pressing operations. The extruded aluminum barrel omits tie-rods for a clean, modern exterior while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration includes a magnet (-S) for proximity sensing via CMSE or DMSE switches housed in the dual side grooves. It is equipped with a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Fluid connections use PT tapered threads, ensuring secure, metal-to-metal sealing in demanding industrial environments.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX10S Is Used
Heavy-Duty Stamping
Ideal for short-stroke metal stamping and marking tasks where the full 6136 N output at 0.5 MPa is required to form thick materials in a single rapid motion.
Industrial Clamping
Provides rigid, high-force clamping for large weldments or machining fixtures, utilizing its 10 mm stroke to lock heavy workpieces securely into position.
Parts Ejection
Functions as a powerful short-stroke ejector in injection molding or metal forming lines, using the integrated magnet and CMSE sensors to verify ejection completion.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX10S the Right Cylinder?
Selecting the SAI125X10-S is optimal when an application demands high force within a minimal 10 mm stroke envelope. If a project requires slightly less thrust, stepping down to the 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to the 160 mm bore provides 10053 N for the most demanding press fits. For this 125 mm bore, the standard operating speed is 30-500 mm/s, and it features a 40 mm cushion length to decelerate the heavy piston at stroke end.
Because the stroke is only 10 mm, rod-bearing bending from side loads is negligible. However, users must remember that standard double-acting cylinders cannot hold a load if air pressure is lost or the valve is centered; the piston will drift. If static holding is mandatory without live pressure, integrate the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. This model serves as a drop-in replacement for any ISO 15552 cylinder with a 125 mm bore, 10 mm stroke, PT port, and a magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAI125AX10S FAQ
The SAI125X10-S generates 6136 N of push force and 5734 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 8590 N, and it reaches a maximum theoretical force of 1251 kgf at 1.0 MPa.
Yes. As a genuine AirTAC ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders of the same 125 mm bore and 10 mm stroke. It uses PT tapered ports and standard mounting accessories like FA flanges or TC trunnions.
