About the Airtac SC80 Standard Cylinder SC80X185STC
The SC80X185STC is an 80 mm bore double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa, rising to 4523 N at the maximum operating pressure of 0.9 MPa. With a 185 mm stroke and a 25 mm diameter piston rod, it is well-suited for medium-duty clamping and pressing tasks where a compact tie-rod body is preferred.
This model is factory-configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) that ships with the TCM1 bracket (F-SC80TC). The 28 mm adjustable air cushion at each end decelerates the piston smoothly, helping to protect tooling in high-cycle applications.

Where the Airtac SC80 Standard Cylinder SC80X185STC Is Used
Part Diverter Gates
The trunnion mount lets the cylinder pivot as it actuates a diverter gate on a conveyor line, while the magnetic piston confirms gate position at each cycle.
Welding Fixture Clamping
Delivers over 4500 N of clamping force at 0.9 MPa to hold steel fabrications securely in a welding jig, with sensor feedback ensuring the clamp is closed before the arc strikes.
Chute or Hopper Door Actuation
Operates a discharge door on a hopper or chute, with the pivoting trunnion mount accommodating the door's swing path and the magnet signaling open/closed status to the controller.
Is the Airtac SC80 Standard Cylinder SC80X185STC the Right Cylinder?
For applications requiring more force, stepping up to the 100 mm bore provides 3927 N at 0.5 MPa, while the 63 mm bore offers 1559 N for lighter, more compact installations. The centre trunnion pivot allows the cylinder to swing, making it ideal for applications where the load moves through an arc.
When replacing this cylinder, match five points: 80 mm bore, 185 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet for sensor compatibility. This is a tie-rod cylinder, not 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 SC80X185STC FAQ
At 0.5 MPa, the cylinder pushes with 2513 N and pulls with 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. You can clamp AirTAC CMSG, DMSG, or EMSG reed or solid-state sensors directly onto the barrel's sensor groove to detect piston position without any additional brackets.
