About the Airtac SC80 Standard Cylinder SC80X270TC
The SC80X270TC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa. Its 80 mm bore and 270 mm stroke suit medium-duty linear actuation where a pivoting mount is needed.
This model features a 25 mm diameter piston rod, PT3/8 ports, and a 28 mm adjustable air cushion at each end. The TC centre trunnion mount (supplied with TCM1 bracket, part F-SC80TC) allows the cylinder to pivot during operation, accommodating swinging loads. Total extended body length is approximately 452 mm.

Where the Airtac SC80 Standard Cylinder SC80X270TC Is Used
Conveyor Diverter Gates
The pivoting TC mount and 270 mm stroke actuate diverter arms on packaging lines, reliably sorting products at standard plant air pressures.
Welding Fixture Clamping
Delivers 2513 N of clamping force at 0.5 MPa for holding fabrications in position, with the trunnion mount allowing the clamp arm to swing clear for part loading.
Agricultural Implement Control
Controls chute doors or flow gates on harvesting equipment, where the centre trunnion absorbs the angular motion of the linkage and the 25 mm rod withstands dusty conditions.
Is the Airtac SC80 Standard Cylinder SC80X270TC the Right Cylinder?
Choose the SC80 for its 2513 N push at 0.5 MPa. If your force requirement is lower, the SC63 bore offers 1559 N at the same pressure; for higher force, step up to the SC100 bore at 3927 N. The TC centre trunnion is ideal for applications requiring angular movement.
For this 270 mm stroke, ensure the rod is not subjected to significant side loading. If the load is not guided externally, consider adding an external guide rail or switching to a guided cylinder to prevent rod bending and premature seal wear. For direct replacement, match bore, stroke, PT port thread, TC mount, and the non-magnet specification.
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 SC80X270TC 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.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. Replace only with another AirTAC SC80 tie-rod cylinder matching the 270 mm stroke, PT3/8 ports, and TC centre trunnion mount.
