About the Airtac SC50 Standard Cylinder SC50X1200SFA
The AirTAC SC50X1200SFA is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a long 1200 mm stroke, it uses a 20 mm diameter piston rod and PT1/4 ports, making it suitable for material transfer and clamping applications requiring extended linear reach.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for precise position feedback. The FA front rectangular flange (F-SC50FA) provides rigid panel mounting at the rod end, while the standard TPU seals ensure reliable operation in temperatures from -20 to +70 °C. The adjustable air cushion at each end decelerates the piston smoothly over a 21 mm cushion length.

Where the Airtac SC50 Standard Cylinder SC50X1200SFA Is Used
Long-Reach Material Transfer
The 1200 mm stroke moves lightweight components between distant conveyor stations, with the magnet enabling end-of-stroke confirmation sensors.
Automated Clamping & Fixturing
Applies 982 N of clamping force at 0.5 MPa to hold workpieces in CNC or welding fixtures, with the FA flange providing rigid front-panel mounting.
Packaging & Palletising Pushers
Pushes cartons or layers onto pallets in packaging lines, using the full 1200 mm stroke for deep reach across roller beds.
Is the Airtac SC50 Standard Cylinder SC50X1200SFA the Right Cylinder?
For applications needing higher force, stepping up to the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If a shorter, more compact stroke is sufficient, the 50 mm bore is also available in standard strokes down to 25 mm. This 1200 mm stroke is at the maximum standard length for the 50 mm bore, so verify that the application does not impose side loads on the fully extended 20 mm rod; an external guide or a guided cylinder is strongly recommended to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match five key points: 50 mm bore, 1200 mm stroke, PT1/4 port thread, FA front flange mounting (F-SC50FA), and the built-in magnet for sensor compatibility. The SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile 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 SC50X1200SFA FAQ
At 0.5 MPa (5 bar) air pressure, the cylinder produces 982 N pushing force 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.
A 1200 mm stroke with a 20 mm rod is highly susceptible to side-load bending at full extension. It is strongly recommended to use an external guide rail or rod support to protect the rod bearing and ensure straight-line motion. The cylinder's adjustable air cushion only decelerates the piston at stroke end; it does not support side loads.
