About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1600
The SC125X1600 is a large-bore, double-acting tie-rod cylinder engineered for applications requiring substantial force over an extended 1600 mm stroke. At the maximum operating pressure of 0.9 MPa, this 125 mm bore unit generates a push force of 11045 N, making it suitable for heavy-duty pushing, lifting, and clamping tasks in industrial automation.
This non-standard stroke length exceeds the 1500 mm maximum standard stroke for the SC125 bore, meaning it is a made-to-order configuration. The cylinder features a robust 32 mm piston rod with an M27x2 thread, a 28 mm adjustable air cushion for smooth end-of-stroke deceleration, and a body length A of 203 mm. Its PT1/2 ports supply the double-acting mechanism, and the operating speed range is 30-500 mm/s, conforming to the ISO 6430 class for larger bore cylinders.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1600 Is Used
Heavy Material Handling
Provides the 11045 N push force at 0.9 MPa needed to shift heavy pallets or steel components on a long-stroke transfer line, where the 1600 mm reach is essential.
Large-Scale Pressing
Delivers consistent, high-force clamping in a large laminating or veneer press, with the adjustable cushion protecting the tooling from impact damage at the end of each cycle.
Structural Testing Rigs
Applies controlled, high-magnitude loads in a test frame for civil engineering materials, where the 30-500 mm/s speed range allows for precise, repeatable test sequences.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1600 the Right Cylinder?
Select the SC125 when your application needs a push force around 6136 N at 0.5 MPa. If a higher force is required, stepping up to the SC160 bore provides 10053 N at the same pressure. For a more compact solution with lower force, the SC100 delivers 3927 N at 0.5 MPa. Always ensure the load is guided externally for strokes of this length, as the 32 mm rod is susceptible to bending under side loads.
For a direct replacement, match five key specifications: the 125 mm bore, the exact 1600 mm stroke, the PT1/2 port thread, the basic mounting configuration (no integrated bracket), and the absence of a built-in magnet. This cylinder is a tie-rod design and will not interchange with ISO 15552 profile cylinders; it is a direct fit only for another AirTAC SC125 cylinder with identical parameters.

- ✓ 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 SC125X1600 FAQ
At 0.7 MPa operating pressure, the theoretical push force is 8590 N. The maximum push force at the 0.9 MPa upper limit is 11045 N. For precise dynamic sizing, always factor in a safety margin for your specific load and friction conditions.
No. For any stroke of 300 mm or more, and especially for a non-standard 1600 mm stroke, the 32 mm diameter rod is vulnerable to bending and buckling under side loads. You must use an external guide rail or a guided cylinder assembly to absorb transverse forces and ensure reliable, long-lasting operation.
