About the Airtac SC80 Standard Cylinder SC80X125H
The AirTAC SC80X125H is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa, making it a robust actuator for medium-duty industrial tasks. Its 125 mm stroke is well within the standard range for the 80 mm bore, and the 25 mm diameter piston rod provides excellent rigidity against bending.
This variant is equipped with Viton (FKM) seals, extending the operating temperature range to 0–150°C for hot or chemically aggressive environments. The cylinder features a 28 mm adjustable air cushion at each end to decelerate the piston smoothly, and uses PT1/4 ports for standard pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X125H Is Used
High-Temperature Actuation
With Viton seals rated to 150°C, this cylinder is ideal for clamping, pressing, or ejecting parts in ovens, autoclaves, and foundry equipment where standard seals would degrade.
Sorting & Diverting Gates
The 2513 N push force at 0.5 MPa provides ample power for medium-duty conveyor gates and diverters in packaging and logistics lines, handling product flow reliably.
Press & Clamp Fixtures
Delivers consistent clamping force for drilling, welding, and assembly fixtures. The adjustable cushioning protects tooling from impact shock at the end of the 125 mm stroke.
Is the Airtac SC80 Standard Cylinder SC80X125H the Right Cylinder?
When sizing, compare the SC80's 2513 N push at 0.5 MPa against the SC63 (1559 N) and SC100 (3927 N) to find the right force band without oversizing. For this 125 mm stroke, side loads are rarely an issue, but always center the load to protect the rod bearing.
To replace an existing cylinder, match five points: 80 mm bore, 125 mm stroke, PT port thread, basic mount (no brackets), and no magnet. This is a tie-rod cylinder, shorter than an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC80 of the same configuration.
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 SC80 Standard Cylinder SC80X125H FAQ
At the standard operating pressure of 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder and its body length (A=182 mm) is shorter than an equivalent ISO 15552 profile cylinder. It will only directly interchange with another AirTAC SC80 tie-rod cylinder matching the same bore, stroke, port, and mounting configuration.
