The AirTAC SC50 Standard Cylinder SC50X720 is a genuine double-acting standard air cylinder with a Ø50mm bore and 720mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X720 is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, scaling up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 50 mm bore and 20 mm piston rod provide a robust linear drive for medium-duty applications requiring a 720 mm stroke, making it well-suited for material transfer and pressing tasks.
This tie-rod cylinder features a 21 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 150 mm, giving a total extended length of approximately 870 mm. With PT1/4 ports and an M16x1.5 rod thread, it integrates easily into standard pneumatic circuits.

Moves components between conveyor lines with a 720 mm reach. The 982 N force at 0.5 MPa reliably pushes pallets or workpieces across transfer stations.
Applies up to 1767 N of clamping force at 0.9 MPa for gluing, riveting, or assembly fixtures. The adjustable cushion protects tooling from impact damage.
Advances sheet material or extrusions into cutting or forming machinery. The 20 mm rod diameter provides good column strength over the 720 mm stroke.
For applications needing more force, stepping up to the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 40 mm bore SC40 delivers 628 N. At a 720 mm stroke, ensure the rod is not subjected to significant side loading; if lateral forces are present, use an external guide rail or a guided cylinder to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match five key points: 50 mm bore, 720 mm stroke, PT1/4 port thread, basic mounting (no accessory brackets), and the absence of a built-in magnet. This ensures a direct dimensional and performance swap for another AirTAC SC50 tie-rod unit.
Quick checklist
At 0.7 MPa operating pressure, the SC50X720 produces a theoretical push force of 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa, due to the area reduction from the 20 mm piston rod.
No. The SC50X720 is a double-acting cylinder and will not hold position if air pressure is lost or the valve is centered. The piston can drift or drop. For load holding without live pressure, you must add an external rod lock, brake, or a pilot-operated check valve.
