About the Airtac SAI125 Standard Air Cylinder SAI125X10
The AirTAC SAI125X10 is a double-acting ISO 15552 profile cylinder engineered for high-force automation in tight stroke envelopes. Delivering 6136 N of push force at just 0.5 MPa, this 125 mm bore unit is purpose-built for heavy pressing and clamping operations within a 10 mm travel range. The extruded aluminum barrel omits tie rods, presenting a clean profile that drops directly into standardized ISO 15552 mounting interfaces.
Because this specific configuration uses a standard carbon steel piston rod and lacks a magnet, it is optimized for purely mechanical force transmission without sensor feedback. For environments requiring high-temperature resilience up to +70 C, the standard TPU seals can be swapped for Viton (H) alternatives. Furthermore, if your sequence control demands integrated pneumatic locking, the related SAIL variant provides an air-released lock mechanism for secure load holding.

Where the Airtac SAI125 Standard Air Cylinder SAI125X10 Is Used
Heavy-Duty Stamping
Ideal for short-travel stamping tasks, delivering 8590 N of push force at 0.7 MPa to form or mark thick materials.
Rigid Workholding
Provides immense clamping pressure to secure heavy workpieces during machining, ensuring zero movement during aggressive milling.
Press Assembly
Perfect for bearing seating and bushing insertion, using its 10 mm stroke to apply controlled, high-impact force.
Is the Airtac SAI125 Standard Air Cylinder SAI125X10 the Right Cylinder?
Selecting this 125 mm bore over the neighboring 100 mm version is justified when you need to step up from 3927 N to a robust 6136 N at 0.5 MPa, effectively doubling your work output within the same 10 mm travel. The PT tapered port thread ensures a positive, leak-free mechanical seal during high-flow pneumatic actuation. Because the stroke is extremely short (10 mm), side-load bending on the rod bearing is negligible compared to longer strokes.
This standard SAI model does not hold its load if air pressure is removed or exhausted; the piston will drift under external force. If your clamping application requires true position maintenance during a loss of supply pressure, you must step up to the SAIL variant or utilize an external pilot-operated check valve. The ISO 15552 mounting dimensions make it fully interchangeable with other profile cylinders of the same bore and stroke.
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.
