About the Airtac SAI125 Standard Air Cylinder SAI125X60
The AirTAC SAI125X60 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial push force of 6136 N at 0.5 MPa, this 125 mm bore unit paired with a 60 mm stroke excels in short-travel, high-impact tasks. The extruded aluminum barrel omits tie-rods, providing a clean profile that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration features a standard carbon steel piston rod and PT tapered port threads. Because it lacks the -S magnet option, position sensing requires external limit switches rather than the integrated sensor grooves. For applications requiring position holding upon air loss, the SAIL variant provides an integrated locking mechanism.

Where the Airtac SAI125 Standard Air Cylinder SAI125X60 Is Used
Heavy-Duty Stamping
Provides the 6136 N force at 0.5 MPa required for short-stroke metal forming and stamping operations.
Industrial Pressing
Ideal for pressing bearings or bushings into heavy housings where a 60 mm stroke is sufficient.
Pallet Halting
Acts as a robust stopper for heavy pallets on assembly lines, absorbing kinetic energy with adjustable cushions.
Is the Airtac SAI125 Standard Air Cylinder SAI125X60 the Right Cylinder?
Select this 125 mm bore when a 100 mm cylinder's 3927 N at 0.5 MPa is insufficient for moving heavy masses. The 60 mm stroke is optimal for compact, high-force clamping or pressing. Operating speed for this bore is 30-500 mm/s.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other standard cylinders with identical bore and stroke dimensions. Ensure your setup uses the PT port thread type and appropriate mounting accessories like FA flanges or CA clevises. Note that standard air cushions only decelerate the piston at end-of-stroke; they do not hold loads if air pressure drops.
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 SAI125X60 FAQ
