About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1130
The AirTAC SC125X1130 is a double-acting tie-rod cylinder delivering a substantial 6136 N of push force at 0.5 MPa, scaling up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 32 mm diameter piston rod and an M27x2 rod-end thread, this big-bore actuator is built for heavy linear work.
This model features a 1130 mm stroke, well within the 1500 mm maximum standard stroke for the 125 mm bore. The adjustable pneumatic cushion at each end (28 mm length) decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 203 mm, giving a total extended length of approximately 1333 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1130 Is Used
Heavy Press & Forming
Provides the high force (up to 11045 N) needed for clamping, bending, or light stamping operations in metal forming cells.
Pallet & Bulk Handling
The long 1130 mm stroke is ideal for pushing heavy pallets or large components across roller conveyors in distribution centers.
Structural Testing Rigs
Applies a controlled, repeatable linear force for load testing on beams, joints, and structural assemblies in civil engineering labs.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1130 the Right Cylinder?
For applications requiring less force, consider stepping down to the 100 mm bore SC series, which provides 3927 N at 0.5 MPa. If the 6136 N output of the SC125X1130 is insufficient, the 160 mm bore model offers 10053 N at the same pressure. At this 1130 mm stroke, the long, extended 32 mm rod is susceptible to bending under side loads; always use an external guide or rod support to prevent bearing damage and ensure linear motion. When replacing an existing cylinder, match five key points: 125 mm bore, 1130 mm stroke, PT port thread, basic (no) mounting, and confirm the magnet requirement (this model has no built-in magnet).
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 SC125X1130 FAQ
At 0.7 MPa operating pressure, the theoretical push force is 8590 N, and the pull force on the retract stroke is 5734 N. The maximum force at 0.9 MPa is 11045 N.
No. The SC125X1130 is a standard double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. For load holding, you must add an external pilot-operated check valve or a mechanical rod brake.
