About the Airtac SC80 Standard Cylinder SC80X125TC
The SC80X125TC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 125 mm stroke, it uses a 25 mm diameter piston rod and PT3/8 ports, providing a robust platform for medium-to-heavy linear actuation tasks.
This model is factory-configured with a TC centre trunnion mount, supplied complete with the TCM1 trunnion bracket (part code F-SC80TC), allowing the cylinder to pivot during operation. The adjustable air cushion at each end, with a 28 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact, while the standard TPU seals ensure reliable performance in temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X125TC Is Used
Conveyor Diverter Gates
The pivoting action of the TC mount and 2513 N push force at 0.5 MPa makes this cylinder ideal for actuating diverter gates on material handling conveyors, smoothly swinging the gate through an arc to redirect packages or bulk materials.
Clamping & Welding Fixtures
With a 125 mm stroke and centre trunnion mounting, this cylinder fits neatly into pivoting clamp arms on welding jigs and assembly fixtures, providing the high force needed to hold heavy workpieces securely during automated processing.
Agricultural Implement Control
The robust tie-rod construction and trunnion mount suit the harsh, dusty conditions of agricultural machinery, where it can control the angle of plough shares, harrows, or discharge chutes with a reliable 2513 N of force.
Is the Airtac SC80 Standard Cylinder SC80X125TC 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 moving up to a 100 mm bore increases it to 3927 N. The TC centre trunnion mount is ideal for applications where the cylinder body needs to swing through an arc, as it absorbs transverse forces that would otherwise bend a rigidly mounted rod.
When selecting a replacement, ensure an exact match on all five key points: 80 mm bore, 125 mm stroke, PT3/8 port thread, TC centre trunnion mounting with the TCM1 bracket, and the absence of a magnet on this non-S variant. This tie-rod cylinder is dimensionally shorter than an ISO 15552 profile, so it is not a drop-in replacement for that standard.
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 SC80X125TC FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides a theoretical push force of 2513 N and a pull force of 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable. It will only directly replace another AirTAC SC80 tie-rod cylinder with the same stroke, TC mount, and PT port thread.
