About the Airtac SC80 Standard Cylinder SC80X290TC
The AirTAC SC80X290TC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 290 mm stroke, this model uses a 25 mm diameter piston rod and features a 28 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact.
This configuration includes the TC centre trunnion mount, supplied with the TCM1 bracket (part code F-SC80TC), which allows the cylinder to pivot during operation—ideal for swinging or articulating loads. The body length A is 182 mm, making the total extended length approximately 472 mm. Standard PT ports (PT3/8) and TPU seals with a -20 to +70 °C operating range are fitted, ensuring reliable performance in general industrial environments.

Where the Airtac SC80 Standard Cylinder SC80X290TC Is Used
Conveyor Diverters
The pivoting action of the TC trunnion mount combined with 2513 N of force at 0.5 MPa makes this cylinder suitable for actuating gate or diverter arms on material handling conveyors.
Clamping & Fixturing
Delivering up to 4523 N of clamping force at 0.9 MPa, the SC80X290TC can securely hold workpieces in CNC machining centres or welding fixtures where a swinging clamp arm is needed.
Agricultural Equipment
The robust tie-rod design and centre trunnion mount are well-suited for the dusty conditions of agricultural machinery, such as actuating chutes or levers on harvesters and spreaders.
Is the Airtac SC80 Standard Cylinder SC80X290TC the Right Cylinder?
For applications requiring less force, stepping down to a 63 mm bore reduces push force to 1559 N at 0.5 MPa, while a step up to a 100 mm bore increases it to 3927 N. The 290 mm stroke on an 80 mm bore is well within standard limits, but always check for side loads; if the load is not guided, consider adding an external guide rail to protect the rod bearing from bending moments.
When replacing this cylinder, match five key points: 80 mm bore, 290 mm stroke, PT3/8 port thread, the TC centre trunnion mounting accessory (F-SC80TC), and the absence of a magnet. This ensures dimensional and functional interchangeability with another AirTAC SC tie-rod cylinder.
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 SC80X290TC FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
The TC mount is a centre trunnion that allows the cylinder body to pivot. It is supplied together with the TCM1 trunnion mounting bracket. The complete accessory part code for this assembly is F-SC80TC.
