About the Airtac SAI125 Standard Air Cylinder SAI125BX60
The AirTAC SAI125X60 is a double-acting ISO 15552 profile cylinder offering a substantial 6136 N push force and 5734 N pull force at 0.5 MPa. This 125 mm bore unit features a 60 mm stroke, making it highly effective for short, heavy-duty clamping or lifting operations. The extruded aluminum barrel design omits tie rods, providing a clean profile while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
Built for demanding environments, this specific configuration incorporates a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. The barrel includes integrated sensor grooves on both sides, and while this unit is supplied without a magnet, adding the -S code enables CMSE or DMSE reed switch detection for automated feedback.

Where the Airtac SAI125 Standard Air Cylinder SAI125BX60 Is Used
Heavy-Duty Stamping
Provides the robust 6136 N force required to execute short-stroke stamping and forming tasks on thick metal sheets.
Industrial Clamping
Ideal for securing heavy workpieces during machining operations, utilizing its 60 mm stroke to lock large components firmly in place.
Pallet Lifting
Generates enough thrust to elevate and lower loaded pallets in automated distribution hubs, handling weights that smaller bores cannot manage.
Is the Airtac SAI125 Standard Air Cylinder SAI125BX60 the Right Cylinder?
Select this 125 mm bore when applications require upward of 6000 N of force at just 0.5 MPa. If your fixture demands less force, stepping down to an 80 mm bore yields 2513 N, which may be sufficient and more compact. Conversely, if you need over 10000 N, the 160 mm bore provides 10053 N. For this 60 mm stroke, side-load stress on the rod bearing is minimal.
This cylinder uses a PT tapered port thread and operates at speeds between 30-500 mm/s. Because it is a standard double-acting cylinder, it will not hold a load if air pressure is lost; for fail-safe holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard cylinder sharing this mounting interface.
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 SAI125BX60 FAQ
At a 0.5 MPa operating pressure, this 125 mm bore cylinder generates 6136 N of push force and 5734 N of pull force. If pressure is increased to 0.7 MPa, the push force reaches 8590 N.
Yes, the SAI125X60 is a genuine ISO 15552 profile cylinder. Its standardized mounting interface and PT G1/2 ports make it dimensionally interchangeable with other ISO 15552 cylinders, allowing for seamless drop-in replacement.
