About the Airtac SC50 Standard Cylinder SC50X1100
The SC50X1100 is a double-acting single-rod pneumatic cylinder from the AirTAC SC tie-rod family, combining a 50 mm bore with an extended 1100 mm stroke. At 0.5 MPa it produces 982 N of push force and 825 N on the pull stroke, while at the maximum operating pressure of 0.9 MPa the thrust reaches 1767 N, driven by a 20 mm diameter piston rod.
This cylinder features a compact body length of 150 mm (dimension A) and an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly. It is equipped with PT1/4 ports and an M16x1.5 rod thread, operating on filtered air within a standard temperature range of -20 to +70 °C using TPU seals.

Where the Airtac SC50 Standard Cylinder SC50X1100 Is Used
Long-Reach Part Transfer
The 1100 mm stroke moves components between distant conveyor stations or work cells, ideal for linear transfer systems requiring consistent mid-range pneumatic force.
Vertical Door Actuation
Operates tall industrial doors or vertical lift gates with 982 N of push force at 0.5 MPa, providing reliable open/close motion in logistics and warehouse environments.
Material Pusher in Sawmills
Pushes timber or sheet goods across a long bed into a cutting zone, using the 20 mm rod and adjustable cushion to handle the inertial load of the moving material.
Is the Airtac SC50 Standard Cylinder SC50X1100 the Right Cylinder?
For applications requiring less force, stepping down to the 40 mm bore SC40 series provides 628 N of push at 0.5 MPa, while moving up to the 63 mm bore SC63 series raises the push force to 1559 N at the same pressure. Always match the replacement cylinder across five key points: bore, stroke, port thread (PT), mounting accessory, and the presence of a magnet.
With a stroke of 1100 mm, this cylinder has a long, unsupported rod that is susceptible to bending under side loads. To prevent premature rod bearing wear or seal failure, use an external linear guide or pair the cylinder with a guided actuator for any application involving lateral forces.
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 SC50 Standard Cylinder SC50X1100 FAQ
At 0.7 MPa operating pressure, the SC50X1100 generates 1374 N of push force during extension and 825 N of pull force during retraction. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching stroke, port, and mounting configuration.
