About the Airtac SC80 Standard Cylinder SC80X1200N
The AirTAC SC80X1200N is a double-acting tie-rod cylinder delivering a substantial push force of 2513 N at 0.5 MPa (4523 N at the 0.9 MPa maximum operating pressure). With an 80 mm bore and a long 1200 mm stroke, this model is built for applications requiring extended linear travel with consistent pneumatic power.
This variant is fitted with NBR (nitrile) seals, offering reliable performance within the standard temperature range of -20 to +70 °C. The cylinder features a 25 mm diameter piston rod with an M20x1.5 male thread, a 28 mm adjustable air cushion for smooth end-of-stroke deceleration, and a PT3/8 port. The total body length A is 182 mm, making the extended length approximately 1382 mm.

Where the Airtac SC80 Standard Cylinder SC80X1200N Is Used
Long-Stroke Material Pusher
The 1200 mm stroke and 2513 N force at 0.5 MPa make this cylinder ideal for pushing heavy boxes or pallets across wide conveyor transfer stations, providing the necessary reach and power.
Automated Panel Gluer
In woodworking or automotive, this cylinder can extend a glue applicator head across a large 1200 mm panel. The adjustable cushion ensures a smooth stop, preventing vibration that could affect bead consistency.
Vertical Bin Door Actuator
With a pull force of 2268 N at 0.5 MPa, it can reliably lift and hold a tall, heavy industrial bin door open, utilizing its full 1200 mm stroke for complete clearance.
Is the Airtac SC80 Standard Cylinder SC80X1200N the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N of push force at 0.5 MPa. If a shorter, more compact solution is acceptable, the 63 mm bore SC63 series delivers 1559 N at the same pressure. Always match the replacement cylinder across five key points: bore (80 mm), stroke (1200 mm), PT port thread, basic mounting, and seal material (NBR).
Given the 1200 mm stroke, careful consideration of side loads is critical. The long, unsupported 25 mm piston rod is susceptible to bending under lateral forces. To ensure long seal and bearing life, use an external guide system or a self-guided tooling plate to absorb any off-axis loads, preventing them from reaching the rod bearing.
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 SC80X1200N FAQ
At the standard operating pressure of 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.
For a stroke of 1200 mm, the 25 mm rod is vulnerable to buckling and side-load damage. It is essential to mount the load on an external linear guide rail or rodless actuator to absorb all transverse forces. The cylinder rod should only be used to push or pull in a straight axial line, connected via a floating joint to prevent binding.
