About the Airtac SC80 Standard Cylinder SC80X550STC
The SC80X550STC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 550 mm stroke, its 25 mm diameter piston rod provides robust linear thrust for medium-to-heavy automation tasks, while the 28 mm adjustable air cushion at each end decelerates the load smoothly.
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 includes the TCM1 bracket, allowing the cylinder body to pivot. The total extended body length is approximately 732 mm (body length A of 182 mm plus the 550 mm stroke).

Where the Airtac SC80 Standard Cylinder SC80X550STC Is Used
Part Diverter on Conveyors
The centre trunnion mount allows the cylinder to pivot, making it ideal for actuating a diverter gate on a conveyor line. The 550 mm stroke provides ample reach to redirect packages or components between lanes.
Clamping in Welding Fixtures
With 2513 N of force at 0.5 MPa, this cylinder delivers the high clamping pressure needed to hold steel fabrications securely in a welding jig. The magnet enables sensor confirmation of the clamp's open/closed state.
Bin Tipper Actuation
The pivoting TC mount and long 550 mm stroke are well-suited for tilting heavy bins or hoppers to empty bulk materials. The adjustable cushioning manages the inertia of the tipping load at the end of the stroke.
Is the Airtac SC80 Standard Cylinder SC80X550STC the Right Cylinder?
Choose the SC80 when your application requires a force between the SC63 (1559 N push at 0.5 MPa) and the SC100 (3927 N push at 0.5 MPa). For this 550 mm stroke, ensure the rod is protected from side loading; an external guide rail or a guided cylinder is strongly recommended to prevent rod bearing wear and bending, as the unsupported 25 mm rod is vulnerable to deflection under non-axial loads.
For a direct replacement, match five key points: an 80 mm bore, 550 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC80TC bracket, and the built-in magnet for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC80X550STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N and the pull force on the return stroke is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
Yes. The 'S' in the model code signifies a built-in magnet on the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the cylinder barrel's tie-rod slots to detect piston position without any additional brackets.
