About the Airtac SC80 Standard Cylinder SC80X50TC
The SC80X50TC is an 80 mm bore double-acting pneumatic cylinder with a short 50 mm stroke, factory-configured with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa it produces 2513 N of push force, and at the maximum operating pressure of 0.9 MPa the thrust reaches 4523 N, driven by a 25 mm diameter piston rod.
This model includes the TCM1 trunnion bracket, allowing the cylinder body to swing as the rod extends and retracts, which is essential for handling misaligned or arcing loads. The adjustable air cushion at each end (28 mm length) decelerates the piston smoothly, protecting the end caps during high-cycle operation. Ports are PT3/8 with an M20x1.5 rod thread.

Where the Airtac SC80 Standard Cylinder SC80X50TC Is Used
Part Diverter Gate
The short 50 mm stroke and trunnion mount allow the cylinder to pivot a diverter flap on a conveyor line. The 2513 N force at 0.5 MPa reliably shifts packages between lanes at high speed.
Welding Fixture Clamp
Mounted on a trunnion, this cylinder swings a clamp arm into place. The 28 mm air cushion absorbs the impact of the fast 50 mm stroke, protecting the fixture from vibration during automated welding.
Process Valve Actuator
The pivoting action suits quarter-turn valve actuation. The cylinder's 4523 N peak force at 0.9 MPa provides ample torque to cycle a sticky ball or butterfly valve handling viscous fluids.
Is the Airtac SC80 Standard Cylinder SC80X50TC the Right Cylinder?
For a centre-pivoting application, the SC80X50TC with its integrated trunnion bracket (F-SC80TC) eliminates the need for a rigid fixed mount. If 2513 N at 0.5 MPa is insufficient, stepping up to the 100 mm bore provides 3927 N; if the force is excessive and a lighter, more compact cylinder is preferred, the 63 mm bore delivers 1559 N.
When replacing an existing cylinder, match five key points: 80 mm bore, 50 mm stroke, PT3/8 port thread, the centre trunnion (TC) mounting style, and the absence of a magnet. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC series or equivalent tie-rod designs.
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 SC80X50TC FAQ
At 0.7 MPa (7 bar), the 80 mm bore SC cylinder generates a push force of 3518 N and a pull force of 2268 N. The maximum operating force at 0.9 MPa is 4523 N push.
Yes, the TC suffix means the cylinder is supplied with the TCM1 trunnion mounting bracket already assembled. The complete accessory code for the bracket set is F-SC80TC. This allows the cylinder body to pivot around its centre of gravity.
