About the Airtac SAI125 Standard Air Cylinder SAI125BX160S
The AirTAC SAI125X160-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 6136 N push force at 0.5 MPa, this 125 mm bore unit is designed to execute demanding linear motion tasks with reliability. The 160 mm stroke provides substantial travel for pressing, clamping, or lifting substantial masses in industrial environments.
Built to precise dimensional standards, this cylinder features a highly corrosion-resistant SUS304 stainless steel piston rod, making it suitable for harsh or washdown environments. The integrated magnet (-S) allows seamless operation with CMSE and DMSE series sensor switches, which mount directly into the extruded aluminum barrel's dual sensor grooves for precise position detection.

Where the Airtac SAI125 Standard Air Cylinder SAI125BX160S Is Used
Heavy-Duty Pressing
Generates 6136 N of thrust at 0.5 MPa for securely seating bearings and bushings in automated assembly lines.
Industrial Clamping
Provides the rigid holding power required to immobilize large weldments or cast components during machining operations.
Pallet Lifting
Delivers the necessary push and pull force to elevate and lower heavy loaded pallets in high-throughput logistics hubs.
Is the Airtac SAI125 Standard Air Cylinder SAI125BX160S the Right Cylinder?
Select this 125 mm bore model when your application requires substantial thrust that exceeds the 3927 N push force of the 100 mm bore variant at 0.5 MPa. If the 6136 N output is excessive for your payload, stepping down to the 80 mm bore yields 2513 N, optimizing air consumption. The PT tapered port threads ensure a robust, sealant-assisted pneumatic connection.
For applications requiring the load to remain safely suspended without continuous air pressure, note that the standard SAI cylinder lacks a mechanical lock. In such scenarios, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant to prevent unintended drift or dropping upon pressure loss.
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 SAI125BX160S FAQ
At a standard operating pressure of 0.5 MPa, this 125 mm bore cylinder generates a push force of 6136 N and a pull force of 5734 N. At 0.7 MPa, the push force increases to 8590 N.
Yes. The SAI125X160-S is a genuine ISO 15552 profile cylinder, meaning its mounting interface and envelope dimensions are fully interchangeable with other ISO 15552 standard cylinders, allowing for seamless drop-in replacement.
