About the Airtac SC80 Standard Cylinder SC80X55STC
The SC80X55STC is an 80 mm bore, 55 mm stroke double-acting pneumatic cylinder delivering 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa). Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide reliable end-of-stroke deceleration for medium-duty linear tasks.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC) with the TCM1 bracket (F-SC80TC) for pivoting applications. The body length A is 182 mm, giving a compact extended length of approximately 237 mm.

Where the Airtac SC80 Standard Cylinder SC80X55STC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder body to pivot as it actuates a diverter gate on a conveyor line, while the magnetic piston enables end-of-stroke position feedback.
Clamping & Fixturing
Delivers 2513 N of clamping force at 0.5 MPa for holding workpieces during machining or welding, with sensor confirmation of the clamped state.
Pivoting Linkage Actuation
The TC mount is ideal for driving a pivoting linkage or lever arm where the cylinder body must swing through an arc during extension and retraction.
Is the Airtac SC80 Standard Cylinder SC80X55STC the Right Cylinder?
Choose the SC80 when your application needs around 2500 N of force at standard shop air. If you can accept a smaller footprint, the SC63 delivers 1559 N at 0.5 MPa; for heavier loads, the SC100 provides 3927 N. The 55 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
For direct replacement, match five points: 80 mm bore, 55 mm stroke, PT port thread, TC centre trunnion mount, and the -S magnet for sensor compatibility. Always use an external guide or guided cylinder if the rod will experience significant side loads, even on short strokes.
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 SC80X55STC FAQ
At 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 at 1.0 MPa is 513 kgf.
Yes, the TC centre trunnion mount is supplied together with the TCM1 trunnion bracket (order code F-SC80TC). The assembly allows the cylinder to pivot freely, which is essential for applications where the rod end travels in an arc.
