About the Airtac SC80 Standard Cylinder SC80X120TC
The AirTAC SC80X120TC is a double-acting pneumatic cylinder with an 80 mm bore and 120 mm stroke, factory-equipped with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa it generates 2513 N pushing force and 2268 N pulling force, rising to 4523 N push at the 0.9 MPa maximum operating pressure.
This model uses a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 ports. The adjustable air cushion at each end (28 mm length) decelerates the piston smoothly. The TC mount includes the TCM1 bracket under part code F-SC80TC, allowing the cylinder to swing as the load moves through an arc.

Where the Airtac SC80 Standard Cylinder SC80X120TC Is Used
Conveyor Diverter Gates
The 80 mm bore provides ample force to shift medium-weight diverter gates on packaging and sortation conveyors, while the centre trunnion mount lets the cylinder pivot freely as the gate swings.
Clamping & Holding Fixtures
With 2513 N at standard line pressure, this cylinder delivers consistent clamping force for CNC welding jigs and assembly fixtures, where the trunnion mount simplifies alignment on pivoting clamp arms.
Agricultural Implement Actuation
The SC80X120TC suits chute controls and bin gates on farm machinery. The centre trunnion absorbs angular misalignment, and the TPU seals handle dusty, damp conditions from -20 to +70 °C.
Is the Airtac SC80 Standard Cylinder SC80X120TC the Right Cylinder?
Choose the SC80 when the SC63's 1559 N push at 0.5 MPa is marginal—this bore steps force up by over 60%. If your stroke exceeds 300 mm with this 25 mm rod, evaluate side-load and bending moment; an external guide or guided cylinder is recommended to protect the rod bearing.
For direct replacement, match five points: 80 mm bore, 120 mm stroke, PT port thread, centre trunnion (TC) mounting with F-SC80TC bracket, and no magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X120TC FAQ
At 0.5 MPa air pressure the cylinder produces 2513 N extending (push) and 2268 N retracting (pull). At 0.7 MPa push force is 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so mounting dimensions and accessory interfaces differ. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder matching the bore, stroke, PT port thread, and TC centre trunnion mount.
