About the Airtac SC80 Standard Cylinder SC80X65TC
The SC80X65TC is an 80 mm bore, 65 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, supplied with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa air pressure it generates 2513 N of push force and 2268 N on the pull stroke, moving a 25 mm diameter piston rod with an adjustable air cushion of 28 mm at each end.
This model's 65 mm stroke sits well within the 1500 mm maximum standard stroke for the 80 mm bore, ensuring standard production lead times. The TC mounting configuration includes the TCM1 trunnion bracket (order code F-SC80TC), allowing the cylinder body to pivot as the load travels through an arc, which reduces rod bending stress compared to a rigidly fixed cylinder in swinging applications.

Where the Airtac SC80 Standard Cylinder SC80X65TC Is Used
Conveyor Diverter Gates
The 65 mm stroke and centre trunnion mount allow the cylinder to pivot smoothly, making it ideal for actuating diverter flaps or gates on packaging and sortation conveyors where the cylinder body must swing through an angle.
Clamping & Welding Fixtures
Delivers a firm 2513 N clamping force at 0.5 MPa for holding steel fabrications or machined parts. The trunnion mount lets the fixture designer place the pivot exactly at the clamp arm's centre of rotation.
Agricultural Implement Control
Used to control chutes, hopper doors, or linkage movements on farming equipment. The TC mount handles the arcing motion of a linkage, while the 80 mm bore provides ample force for heavy grain or soil loads.
Is the Airtac SC80 Standard Cylinder SC80X65TC the Right Cylinder?
Choose the SC80 bore when your application needs between roughly 2500 N and 4500 N of force at typical shop air pressures. If 2513 N at 0.5 MPa is more than required, stepping down to the 63 mm bore (1559 N at 0.5 MPa) can reduce air consumption and physical size. For higher force, the 100 mm bore provides 3927 N at the same pressure.
To replace an existing cylinder, match five key points: 80 mm bore, 65 mm stroke, PT1/8 port thread, centre trunnion (TC) mounting with the F-SC80TC bracket, and no magnet (this model does not include the -S magnet option for sensors). Always verify the trunnion pin centreline dimension against the original to ensure the pivot point is identical.
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 SC80X65TC FAQ
At the standard operating pressure of 0.5 MPa, the cylinder produces 2513 N of force when extending (push) and 2268 N when retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. These values are based on the 80 mm bore and 25 mm rod diameter.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. The mounting dimensions, tie-rod spacing, and overall envelope are different. It will only directly interchange with another AirTAC SC tie-rod cylinder of the same bore, stroke, and mounting configuration.
