About the Airtac SC80 Standard Cylinder SC80X20TC
The SC80X20TC is a double-acting pneumatic cylinder with an 80 mm bore and a short 20 mm stroke, built for compact linear movements that require pivoting freedom. It generates 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa, driven by a 25 mm diameter piston rod with M20x1.5 male threads.
This model comes factory-assembled with the TC centre trunnion mount, supplied together with the TCM1 bracket (order code F-SC80TC). The trunnion allows the cylinder body to pivot during operation, making it ideal for swinging or articulating linkages where the rod must follow a curved path without binding.

Where the Airtac SC80 Standard Cylinder SC80X20TC Is Used
Short-Stroke Clamping
Delivers a powerful 20 mm clamping stroke with 2513 N of force at 0.5 MPa, perfect for holding workpieces in machining or welding fixtures.
Diverter Gate Actuation
The centre trunnion mount lets the cylinder pivot as it pushes a small diverter gate on a conveyor, directing parts with a crisp 20 mm movement.
Linkage Pin Actuator
Ideal for actuating a short-throw linkage or toggle mechanism where the cylinder body must swing, eliminating side-load stress on the rod bearing.
Is the Airtac SC80 Standard Cylinder SC80X20TC the Right Cylinder?
Choose the SC80X20TC when your mechanism needs to pivot and the stroke is very short. If the 2513 N push at 0.5 MPa is more than required, stepping down to a 63 mm bore reduces force to 1559 N at the same pressure. For higher force, the 100 mm bore delivers 3927 N at 0.5 MPa.
For a direct replacement, match five points exactly: 80 mm bore, 20 mm stroke, PT port thread, TC centre trunnion mounting, and the absence of a magnet. 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 SC80X20TC FAQ
At 0.7 MPa (7 bar) supply pressure, the 80 mm bore SC cylinder produces 3518 N of push force. The pull force on the retract stroke is 2268 N at 0.5 MPa, reduced by the 25 mm rod area.
The TC suffix means this cylinder is supplied with a centre trunnion and TCM1 bracket for pivoting. If you need a basic cylinder without a bracket, order the SC80X20 model. The trunnion is integral to the tie-rod assembly and should not be removed for fixed mounting.
