About the Airtac SC80 Standard Cylinder SC80X1250TC
The SC80X1250TC is a double-acting pneumatic cylinder delivering 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa). With an 80 mm bore and 1250 mm stroke, it features a 25 mm diameter piston rod, PT3/8 ports, and a 28 mm adjustable air cushion for reliable end-of-stroke deceleration.
This model is configured with a TC centre trunnion mount (supplied with TCM1 bracket, order code F-SC80TC), allowing the cylinder to pivot during operation. The standard TPU seals provide a working temperature range of -20 to +70 °C, and the body length A is 182 mm.

Where the Airtac SC80 Standard Cylinder SC80X1250TC Is Used
Long-Reach Material Transfer
Pushes or pulls components across wide conveyor gaps where a pivoting cylinder mount is required to follow the load arc.
Clamping & Fixturing
Applies 2513 N of clamping force at standard line pressure, ideal for large weld fixtures or assembly jigs needing a swing-away cylinder.
Agricultural Equipment Actuation
Operates chutes, gates, or diverters on harvesters and spreaders, with the trunnion mount absorbing misalignment in rugged conditions.
Is the Airtac SC80 Standard Cylinder SC80X1250TC the Right Cylinder?
For lower force requirements, stepping down to a 63 mm bore (1559 N at 0.5 MPa) may suffice; for heavier loads, the 100 mm bore offers 3927 N. At 1250 mm stroke, the extended rod is susceptible to bending under side loads—always use an external guide or ensure purely axial loading. When replacing, match bore, stroke, PT port thread, TC centre trunnion mounting, and confirm the magnet requirement (this model has no built-in magnet).
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 SC80X1250TC 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, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. A 1250 mm stroke with a 25 mm rod is highly susceptible to bending and bearing wear under side loads. You must guide the load externally with linear rails or rods, or switch to a guided cylinder assembly. The adjustable air cushion only decelerates the piston, it does not support side forces.
