About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1330S
The AirTAC SC125X1330S is a large-bore, double-acting pneumatic cylinder with a 125 mm bore and an extended 1330 mm non-standard stroke, built for heavy industrial linear actuation. At the maximum operating pressure of 0.9 MPa, this tie-rod cylinder generates a substantial push force of 11045 N, making it suitable for demanding clamping, pressing, and lifting applications.
This model features a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the barrel for precise end-of-stroke position sensing. The 32 mm diameter piston rod provides high rigidity, while the 28 mm adjustable air cushion at each end decelerates the high inertial load smoothly. The total extended body length is approximately 1533 mm, and it uses a PT1/2 port for pneumatic connections.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1330S Is Used
Heavy Press Tool Actuation
Provides the high 11045 N thrust at 0.9 MPa needed to operate large forming dies, punch presses, or heavy-duty clamping fixtures in metal fabrication cells.
Timber & Panel Handling
The 1330 mm stroke is ideal for pushing or stacking large-format plywood sheets and timber boards in sawmill and furniture production lines, with sensors confirming full extension.
Palletizer Pusher Arm
Delivers the long reach and high force to transfer fully loaded heavy pallets onto conveyor systems, where the built-in magnet enables reliable cycle counting and position verification.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1330S the Right Cylinder?
When selecting a cylinder for this force class, the SC125 bore provides 6136 N of push force at 0.5 MPa. If your application requires higher force, stepping up to the SC160 bore offers 10053 N at the same pressure. For lower force requirements, the SC100 bore delivers 3927 N at 0.5 MPa. Always match the bore, stroke, PT port thread, and the -S magnet option when replacing an existing unit.
With a stroke length of 1330 mm, the piston rod extends significantly, creating a large moment arm. Side loads on the unsupported rod can cause bending, seal wear, and premature failure. For this non-standard stroke, it is critical to guide the load externally with rails or use a guided cylinder variant to prevent any radial force from reaching the rod bearing.
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 AIRTAC SC125-160 Standard Cylinder SC125X1330S FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No, this cylinder is designed for axial loads only. The 1330 mm stroke creates a long lever arm, making the 32 mm rod susceptible to bending under side loads. You must use an external linear guide or rail system to absorb any radial forces and protect the rod bearings and seals.
