About the Airtac SC50 Standard Cylinder SC50X1105S
The AirTAC SC50X1105-S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and an extended 1105 mm stroke, built with a built-in magnet for sensor compatibility. This non-standard stroke length exceeds the standard 1200 mm maximum, making it a made-to-order unit for applications requiring precise long-reach linear motion.
At 0.5 MPa, this cylinder delivers 982 N of push force and 825 N of pull force, scaling to 1767 N at the maximum operating pressure of 0.9 MPa. The 20 mm diameter piston rod features an M16x1.5 male thread, and the body length A is 150 mm, resulting in a total extended length of approximately 1255 mm. It uses a 21 mm adjustable air cushion and PT1/4 ports.

Where the Airtac SC50 Standard Cylinder SC50X1105S Is Used
Long-Stroke Part Transfer
Moves components across a wide gap in automated assembly lines, using the 1105 mm reach to bridge conveyor sections where a standard-stroke cylinder falls short.
Automated Sorting Gate
Acts as a long-throw actuator for diverting packages or materials on high-speed sorting systems, with the built-in magnet providing end-of-stroke confirmation via CMSG sensors.
Custom Machine Tool Actuation
Provides the extended linear motion for a custom-built clamping or feeding mechanism on a special-purpose machine, delivering 1767 N of clamping force at full pressure.
Is the Airtac SC50 Standard Cylinder SC50X1105S the Right Cylinder?
Select the SC50 bore when your application needs around 982 N of force at standard plant air pressure; if you require more force, step up to the SC63 bore which provides 1559 N at the same 0.5 MPa. For this 1105 mm stroke, carefully evaluate side-loading conditions. Long, unsupported strokes on a 20 mm rod are susceptible to bending under lateral forces—consider adding an external guide rail or switching to a guided cylinder assembly to protect the rod bearings and seals from premature wear.
To ensure a correct replacement, match five key points: 50 mm bore, 1105 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting style. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC series cylinders.
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 SC50X1105S FAQ
At 0.5 MPa (approximately 73 psi), the cylinder produces 982 N of push force and 825 N of pull 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.
The 1105 mm stroke is non-standard and made-to-order. To replace an existing cylinder, you must match the 50 mm bore, 1105 mm stroke, PT1/4 ports, and the -S magnet option. This is an AirTAC SC tie-rod cylinder, so it will only directly interchange with another AirTAC SC unit of the same specifications, not with ISO 15552 profile cylinders.
