About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1130H
The AirTAC SC125X1130H is a double-acting tie-rod cylinder with a 125 mm bore and an 1130 mm stroke, built with high-temperature Viton (FKM) seals that shift the operating range to 0–150 °C. At 0.5 MPa it pushes with 6136 N and pulls with 5734 N, while at the maximum operating pressure of 0.9 MPa the thrust reaches 11045 N — enough for heavy pressing, clamping, and lifting tasks in hot environments.
This model uses a 32 mm piston rod with an M27×2 knuckle thread and PT1/2 ports. The adjustable air cushion at each end (28 mm length) decelerates the piston smoothly, and the body length A of 203 mm keeps the overall envelope compact for its force class. The 1130 mm stroke is within the 1500 mm maximum standard stroke for bore 125, so this is a standard-stroke configuration.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1130H Is Used
High-Temperature Pressing
Viton seals allow continuous operation up to 150 °C, making the SC125X1130H suitable for hot presses, autoclave actuators, and foundry mould-clamping stations where standard seals would degrade.
Heavy Material Handling
With 6136 N push at 0.5 MPa and a long 1130 mm stroke, this cylinder can push or lift heavy bins, pallets, and structural components across conveyors and transfer stations.
Large-Format Clamping
The 11045 N thrust at 0.9 MPa delivers the force needed for large welding jigs, structural bonding fixtures, and assembly tools that require a long stroke to clear the workpiece.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1130H the Right Cylinder?
Choose the SC125 when your application needs roughly 6136 N push at 0.5 MPa; if you can accept a lower force, stepping down to the SC100 (3927 N push at 0.5 MPa) saves space and air consumption. For strokes above 300 mm like this 1130 mm unit, the long unsupported rod is sensitive to side loads — add an external linear guide or switch to a guided cylinder if the load is not perfectly axial. When replacing an existing cylinder, match five points: 125 mm bore, 1130 mm stroke, PT1/2 ports, the specific mounting accessory (this basic model has none), and the magnet option (this unit 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 SC125X1130H FAQ
At 0.5 MPa the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa push rises to 8590 N, and at the maximum operating pressure of 0.9 MPa it reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No — the SC125 is a double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centred. For load holding without live pressure, add a pilot-operated check valve, a mechanical rod lock, or an external brake.
