About the Airtac SC50 Standard Cylinder SC50X680
The SC50X680 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 680 mm stroke. At 0.5 MPa it generates 982 N pushing force and 825 N pulling force, while at the maximum operating pressure of 0.9 MPa the push thrust reaches 1767 N, making it suitable for medium-duty linear transfer tasks.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, and the body length A is 150 mm. The 680 mm stroke is within the 1200 mm maximum standard stroke for bore 50, so it is a standard-stroke configuration.

Where the Airtac SC50 Standard Cylinder SC50X680 Is Used
Part Transfer
Pushes or pulls components between conveyor lanes or indexing stations with 982 N of force, handling medium-weight pallets or fixtures.
Clamping & Pressing
Applies up to 1767 N of clamping force at 0.9 MPa for holding workpieces during welding, gluing, or light assembly press operations.
Material Feed
Advances strip, sheet, or bar stock into a cutting or forming zone with a consistent 680 mm feed stroke, driven by the double-acting air cycle.
Is the Airtac SC50 Standard Cylinder SC50X680 the Right Cylinder?
Choose the SC50X680 when your application needs around 982 N of push force at standard plant air pressure. If you require more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N at 0.5 MPa; for a lighter, more compact solution the 40 mm bore (SC40 series) delivers 628 N. The 680 mm stroke is moderately long: ensure the rod is not subjected to significant side loading, as a 20 mm rod extended this far can bend under lateral force. For guided motion, pair the cylinder with an external linear guide or consider a guided cylinder unit.
For direct replacement, match five key points: 50 mm bore, 680 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no built-in magnet. This is a tie-rod cylinder with a shorter overall length than an ISO 15552 profile, so it is not dimensionally interchangeable with ISO 15552 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 SC50X680 FAQ
At 0.5 MPa (approx. 5 bar) the push force is 982 N and the pull force is 825 N. At 0.7 MPa push force rises to 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf (1961 N).
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder of the same bore and stroke, so the mounting dimensions and overall length differ. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching bore, stroke, PT ports, and basic mounting.
