About the Airtac SC50 Standard Cylinder SC50X1100SFA
The AirTAC SC50X1100SFA is a double-acting single-rod pneumatic cylinder delivering 982 N of push force and 825 N of pull force when operated at 0.5 MPa. With a 50 mm bore and an extended 1100 mm stroke, it uses a 20 mm diameter piston rod and features an adjustable air cushion length of 21 mm to decelerate end-of-stroke loads smoothly.
This model is configured with a built-in magnet (-S) for mounting CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel, enabling precise position feedback. The FA front rectangular flange (F-SC50FA) allows rigid panel mounting on the rod side, while the standard PT1/4 port threads and TPU seals with a -20 to +70 °C operating range suit general industrial automation.

Where the Airtac SC50 Standard Cylinder SC50X1100SFA Is Used
Long-Reach Material Transfer
The 1100 mm stroke and 982 N push force at 0.5 MPa suit long-distance part transfer stations on packaging or assembly lines, where the front flange mount secures the cylinder to a machine frame.
Automated Sorting Gates
With a built-in magnet for end-of-stroke sensors, this cylinder reliably actuates diverter gates on conveyor systems, confirming gate position with CMSG/DMSG switches before product flow is redirected.
Pallet Dispensing Systems
Used in pallet magazine dispensers, the 1100 mm stroke pushes a single pallet from a stack onto a roller conveyor, leveraging the 20 mm rod’s strength for consistent, repeatable cycles in logistics hubs.
Is the Airtac SC50 Standard Cylinder SC50X1100SFA the Right Cylinder?
For applications requiring less force, consider stepping down to the 40 mm bore SC40 series, which provides 628 N of push force at 0.5 MPa. If higher force is needed, the 63 mm bore SC63 series offers 1559 N at the same pressure. At this 1100 mm stroke length, the unsupported rod is susceptible to bending under side loads; use an external linear guide or a guided cylinder assembly to protect the rod bearing and ensure long service life. To ensure a correct replacement, match five key points: 50 mm bore, 1100 mm stroke, PT1/4 port thread, FA front flange mounting accessory, and the built-in magnet (-S) for sensor compatibility.
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 SC50X1100SFA FAQ
At 0.5 MPa, the cylinder produces 982 N pushing and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Match these five specifications exactly: 50 mm bore, 1100 mm stroke, PT1/4 pneumatic ports, FA front flange mounting, and the built-in magnet (-S) for sensor mounting. This tie-rod cylinder is dimensionally interchangeable only with another AirTAC SC50 tie-rod cylinder of the same configuration.
