About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X180
The SC125X180 is a double-acting tie-rod cylinder delivering a substantial 6136 N of push force at 0.5 MPa (11045 N at the maximum operating pressure of 0.9 MPa). With a 125 mm bore and a 32 mm piston rod, this model is built for heavy-duty linear applications where high force in a compact envelope is critical.
This 180 mm stroke variant stays well within the 1500 mm maximum standard stroke for the 125 mm bore. It features a 28 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly, and its body length A is 203 mm. The standard PT1/2 port and M27x2 rod thread ensure straightforward integration into existing pneumatic circuits.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X180 Is Used
Heavy Press & Clamping
Generates over 11,000 N of force at 0.9 MPa for holding, pressing, or clamping large workpieces in machine tools and welding fixtures.
Material Forming
Provides the high thrust needed for bending, punching, or light forming operations in metal and plastic fabrication cells.
Palletising & Lift Systems
Powers vertical lift stations and palletisers, handling heavy totes and pallets with the robust 32 mm piston rod and adjustable end-cushioning.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X180 the Right Cylinder?
Select the SC125X180 when your application requires a force class above what an SC100 can provide (3927 N at 0.5 MPa) but does not yet need the full capacity of an SC160 (10053 N at 0.5 MPa). Always verify that the 32 mm rod is adequately supported for the stroke length, especially if any side load is present.
For a direct replacement, match five key points: 125 mm bore, 180 mm stroke, PT1/2 port thread, basic mounting (no bracket), and the absence of a magnet. This SC cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders, but it conforms to the ISO 6430 class for big-bore cylinders.
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 SC125X180 FAQ
At the standard 0.5 MPa operating pressure, the push force is 6136 N. At 0.7 MPa it is 8590 N, and at the maximum operating pressure of 0.9 MPa it reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 profile cylinder, so mounting dimensions and body length A (203 mm) will differ. It is an ISO 6430 class cylinder. For a drop-in replacement, match the bore, stroke, port thread (PT1/2), and mounting accessory from another SC series cylinder.
