About the Airtac SC50 Standard Cylinder SC50X155SFA
The AirTAC SC50X155SFA is a double-acting single-rod cylinder delivering 982 N of push force at 0.5 MPa and 1767 N at 0.9 MPa, making it a robust mid-range actuator for industrial automation. With a 155 mm stroke and a 20 mm diameter rod, it provides a balanced combination of reach and force, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact.
This model includes a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors and an FA front rectangular flange (accessory F-SC50FA) for secure panel or bulkhead mounting. The standard TPU seals and PT ports suit general-purpose pneumatic systems operating from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X155SFA Is Used
Clamping & Fixturing
Front-flange mounting and 982 N of clamping force at standard line pressure make this cylinder ideal for secure workpiece holding in CNC jigs and assembly fixtures.
Part Transfer
The 155 mm stroke and magnetic piston enable precise end-of-stroke sensing for reliable part pushing or lifting on packaging and material-handling conveyors.
Press & Forming Assist
With 1767 N of force at 0.9 MPa, it provides a compact power stroke for light pressing, stamping, or forming operations where panel mounting simplifies integration.
Is the Airtac SC50 Standard Cylinder SC50X155SFA the Right Cylinder?
Select the SC50X155SFA when your application needs a 50 mm bore with sensor feedback and rigid front-panel mounting. If your force requirement is lower, stepping down to the 40 mm bore reduces push force to 628 N at 0.5 MPa; for higher thrust, the 63 mm bore provides 1559 N. For this 155 mm stroke, side loads are generally well-managed by the rod bearing, but always align the load axially. When replacing, match bore, stroke, PT port thread, FA flange mount, and the -S magnet option to ensure full 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 SC50X155SFA FAQ
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It directly replaces another AirTAC SC50 cylinder with matching stroke, PT ports, FA front flange, and -S magnet.
