About the Airtac SC80 Standard Cylinder SC80X140TC
The SC80X140TC is an 80 mm bore, 140 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. At 0.5 MPa it provides 2513 N of push force and 2268 N on the pull stroke, driven by a 25 mm diameter piston rod with M20x1.5 male threads. The 140 mm stroke sits well within the 1500 mm maximum standard stroke for this bore, and the adjustable air cushion (28 mm length) decelerates the piston smoothly at each end.
This model is factory-configured with the TC centre trunnion mounting, supplied complete with the TCM1 bracket (order reference F-SC80TC). The trunnion allows the cylinder body to pivot, making it the correct choice for swinging or articulating loads. Ports are PT1/8 with the standard TPU/NBR seal package rated for -20 to +70 °C. The body length A is 182 mm, giving a total extended length of approximately 322 mm.

Where the Airtac SC80 Standard Cylinder SC80X140TC Is Used
Conveyor Diverter Gates
The 2513 N push force at 0.5 MPa easily actuates diverter arms on packaging and sortation conveyors. The centre trunnion mount lets the cylinder pivot as the gate swings through its arc.
Clamping & Welding Fixtures
Provides consistent clamping pressure for metal fabrication jigs. The adjustable cushion protects the fixture from impact shock, and the trunnion mount allows the cylinder to self-align during clamp/unclamp cycles.
Agricultural Implement Control
Operates chute deflectors or hopper doors on planting and harvesting equipment. The tie-rod construction is serviceable, and the pivot mount handles the off-axis motion common in field machinery.
Is the Airtac SC80 Standard Cylinder SC80X140TC the Right Cylinder?
Select the SC80 bore when your application needs roughly 2500 N of force at standard plant pressure. If the load is lighter, stepping down to the 63 mm bore saves space and air (1559 N at 0.5 MPa); for heavier work, the 100 mm bore delivers 3927 N at the same pressure. The 140 mm stroke is a standard catalogue length.
For any stroke over 300 mm, consider the risk of side-load bending on the 25 mm rod—external linear guides or a guided cylinder protect the rod bearing. When replacing an existing cylinder, match five points: 80 mm bore, 140 mm stroke, PT port thread, TC centre-trunnion mounting with TCM1 bracket, and confirm the magnet option (this unit has no built-in magnet).
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 SC80X140TC FAQ
At 0.5 MPa (5 bar) the cylinder produces 2513 N pushing out and 2268 N pulling in. At the maximum operating pressure of 1.0 MPa, theoretical push force reaches 5026 N. Always apply a safety factor for dynamic loads.
Yes, provided the existing unit is an 80 mm bore tie-rod cylinder with a 140 mm stroke and PT1/8 ports. The TC mount includes the TCM1 bracket; verify the trunnion pin diameter and position match your machine's mounting points. This cylinder does not have a built-in magnet, so if your application uses magnetic sensors, order the -S variant instead.
