About the Airtac SC80 Standard Cylinder SC80X70TC
The AirTAC SC80X70TC is an 80 mm bore, 70 mm stroke double-acting pneumatic cylinder supplied with a centre trunnion mount for pivoting applications. At 0.5 MPa it generates 2513 N pushing force and 2268 N pulling force, rising to 4523 N at the 0.9 MPa maximum operating pressure.
This model features a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 port connections. The 28 mm adjustable air cushion at each end decelerates the piston smoothly, while the TC centre trunnion (supplied with TCM1 bracket, order code F-SC80TC) allows the cylinder to swing through an arc, ideal for clamping and lever-drive mechanisms.

Where the Airtac SC80 Standard Cylinder SC80X70TC Is Used
Conveyor Diverter Gates
The pivoting TC mount and 2513 N push force at 0.5 MPa allow the SC80X70TC to swing diverter gates on packaging and sortation conveyors, directing product flows reliably.
Welding Fixture Clamps
Centre trunnion mounting provides a clean swing arc for clamping arms in welding jigs. The 28 mm cushion absorbs impact at stroke end, protecting the fixture from vibration.
Process Valve Actuation
With 4523 N of thrust at 0.9 MPa, this cylinder actuates quarter-turn ball or butterfly valves via a scotch-yoke mechanism, where the trunnion mount absorbs reaction torque.
Is the Airtac SC80 Standard Cylinder SC80X70TC the Right Cylinder?
Choose the SC80 bore when your application needs roughly 2500 N of force at standard shop air; if you can accept less force, the 63 mm bore delivers 1559 N at 0.5 MPa and saves space. For heavier loads, the 100 mm bore provides 3927 N at the same pressure. The 70 mm stroke is a standard length within the 80 mm bore’s 1500 mm maximum.
When replacing an existing cylinder, match five points: 80 mm bore, 70 mm stroke, PT3/8 ports, centre trunnion (TC) mounting, and confirm whether a magnet (-S) is needed. The centre trunnion mount lets the cylinder pivot, so ensure the TCM1 bracket and pin are correctly sized for your clevis.
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 SC80X70TC FAQ
At 0.7 MPa (7 bar) the 80 mm bore generates 3518 N extending and 3175 N retracting. The maximum operating force at 0.9 MPa is 4523 N push / 4081 N pull.
The TC suffix means the cylinder body includes the centre trunnion bosses. It is supplied with the TCM1 bracket (F-SC80TC) and is designed to pivot on that bracket. If you need a fixed foot mount instead, order the basic SC80X70 with an LB foot bracket (F-SC80LB) added separately.
