About the Airtac SC80 Standard Cylinder SC80X1120
The AirTAC SC80X1120 is a double-acting tie-rod cylinder delivering a substantial 2513 N of push force when operated 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 long 1120 mm stroke, this model is built for applications requiring extended linear travel, such as material transfer or door actuation on large machinery.
This cylinder features a 25 mm diameter piston rod and a 28 mm adjustable air cushion at each end to decelerate the load smoothly, reducing end-of-stroke impact. The total extended body length is approximately 1302 mm, combining the 182 mm body length with the 1120 mm stroke. It uses a PT3/8 port and is rated for an operating pressure range of 0.15 to 1.0 MPa with standard TPU seals suitable for -20 to +70 C.

Where the Airtac SC80 Standard Cylinder SC80X1120 Is Used
Long-Stroke Material Pusher
The 1120 mm stroke is ideal for pushing heavy bins or pallets off a conveyor line, where the 2513 N force at 0.5 MPa easily handles sliding friction over a long distance.
Large Door or Damper Actuation
Provides the extended linear travel needed to open and close large hopper doors or ventilation dampers in processing plants, with adjustable cushioning to soften the stop.
Long-Reach Part Transfer
Moves heavy fabricated parts between distant stations on an assembly jig, leveraging the 25 mm rod's strength when the load is properly supported on external linear guides.
Is the Airtac SC80 Standard Cylinder SC80X1120 the Right Cylinder?
For applications needing slightly less force in a more compact envelope, stepping down to the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa. Conversely, if 2513 N is insufficient, the 100 mm bore SC100 series offers 3927 N at the same pressure. This cylinder is a direct replacement only for another AirTAC SC80 tie-rod cylinder with matching 1120 mm stroke, PT3/8 port, basic mounting, and no magnet.
With a stroke of 1120 mm, the piston rod is highly extended and vulnerable to bending under side loads. It is critical to ensure the load is guided externally and aligned axially with the rod. For applications with inherent side forces, consider pairing this cylinder with an external guide rail or selecting a guided cylinder unit to prevent premature rod bearing and seal wear.
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 SC80X1120 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.
No, a tie-rod cylinder should not absorb side loads. At a 1120 mm stroke, the 25 mm rod is fully extended and susceptible to bending. You must use an external guide system to support the load and keep it aligned with the rod axis to ensure long service life.
