About the Airtac SAI125 Standard Air Cylinder SAI125X150TC
The AirTAC SAI125X150 is a double-acting ISO 15552 profile cylinder built for heavy-duty operations. It generates 6136N of push force at 0.5MPa, extending to a 150mm stroke. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that matches standard ISO 15552 mounting dimensions exactly.
This configuration features a standard carbon steel piston rod and PT tapered port threads. It lacks a magnet (-S), so it cannot host CMSE or DMSE sensor switches. If your workflow requires position detection, you must select a -S variant. For environments exceeding standard temperature limits, Viton (H) seals are available instead of the default TPU.

Where the Airtac SAI125 Standard Air Cylinder SAI125X150TC Is Used
Heavy Stamping
Drives large metal forming presses requiring substantial push force and a 150mm stroke.
Pallet Diverting
Shifts heavy-loaded pallets transversely on high-throughput packaging conveyor lines.
Automated Clamping
Secures bulky automotive components during machining and welding operations.
Is the Airtac SAI125 Standard Air Cylinder SAI125X150TC the Right Cylinder?
With a 125mm bore providing 6136N of thrust at 0.5MPa, stepping down to a 100mm bore yields 3927N, while scaling up to a 160mm bore offers 10053N. The TC trunnion mount supplied here allows pivot articulation. Because this is a standard cylinder, it will drift if air pressure is lost; use the SAIL or BSAI variants if your application requires strict load holding without live pressure.
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.
