About the Airtac SC50 Standard Cylinder SC50X920SFAY
The AirTAC SC50X920SFAY is a double-acting single-rod tie-rod cylinder with a 50 mm bore and a 920 mm stroke, delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. It features a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 port connections, making it a robust choice for medium-duty linear actuation tasks.
This model is configured with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG position sensors, and comes with a front rectangular flange (FA mount, accessory F-SC50FA) for secure panel or bulkhead installation. The adjustable pneumatic cushion at each end (21 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact for a total extended body length of approximately 1070 mm.

Where the Airtac SC50 Standard Cylinder SC50X920SFAY Is Used
Material Transfer Gates
The 920 mm stroke and 1767 N push force at 0.9 MPa are well-suited for actuating diverter gates on wide conveyor lines, where the FA front flange allows direct mounting to the gate framework.
Automated Press Feeders
Delivers consistent, repeatable linear motion for feeding sheet material into stamping presses, with the built-in magnet enabling end-of-stroke sensing for cycle control.
Palletising Pushers
Ideal for pushing boxes or trays across a roller bed onto a pallet. The tie-rod design handles repetitive impact, and the adjustable cushion protects the cylinder at the end of the long stroke.
Is the Airtac SC50 Standard Cylinder SC50X920SFAY the Right Cylinder?
The SC50 bore sits between the lighter SC40 (628 N at 0.5 MPa) and the heavier SC63 (1559 N at 0.5 MPa). If your application requires higher force or a stiffer 20 mm rod for the same 920 mm stroke, stepping up to an SC63 is advisable; for a more compact solution with lower force, the SC40 is an option. Always match bore, stroke, PT port thread, FA front flange mounting, and the -S magnet when replacing an existing unit.
With a 920 mm stroke, the rod is fully extended well beyond the body length, making it susceptible to bending under side loads. For this stroke length, use an external linear guide or rod support to prevent bearing wear and rod buckling, or consider a guided cylinder assembly if the load is not purely axial.
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 SC50X920SFAY FAQ
At the standard 0.5 MPa operating 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.
Direct replacement requires matching the FA front flange mount. If your existing cylinder uses a different mount (such as foot or clevis), you will need to either adapt the machine frame or order the correct mounting variant, such as the SC50X920SLB for foot mounting. The critical matching points are the 50 mm bore, 920 mm stroke, PT1/4 ports, and the -S magnet.
