The AirTAC SC50 Standard Cylinder SC50X30 is a genuine double-acting standard air cylinder with a Ø50mm bore and 30mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X30 is a compact-stroke member of the AirTAC SC tie-rod cylinder family, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 30 mm stroke suits short linear positioning tasks where a 20 mm diameter piston rod and a body length of just 150 mm keep the overall envelope tight.
This double-acting cylinder uses filtered air to power both extend and retract strokes, with an adjustable pneumatic cushion at each end to decelerate the piston smoothly over 21 mm. The standard PT1/4 port threads and M16x1.5 rod thread provide straightforward pneumatic connections and tooling attachment.

The 30 mm stroke is ideal for end-stops and part gates on conveyors, providing a firm 982 N holding force to accurately position light packages or components without excessive travel.
Used in jigs and welding fixtures, the SC50X30 applies consistent clamping pressure. The 20 mm rod is rigid enough for direct push-plate mounting in short-stroke, low-side-load scenarios.
Delivers up to 1767 N for light pressing, stamping, or ejecting parts from a mold. The adjustable cushion protects the tooling from impact damage at the end of the fast 30 mm cycle.
For applications needing slightly more force in the same bore class, the 63 mm bore SC63 series steps up to 1559 N at 0.5 MPa. Conversely, if 982 N exceeds the requirement and a lighter, more compact unit is preferred, the 40 mm bore SC40 series offers 628 N at 0.5 MPa. When replacing this cylinder, match five key points: 50 mm bore, 30 mm stroke, PT port thread, basic mounting (no accessory brackets), and the absence of a magnet. This ensures a direct dimensional and performance interchange with another AirTAC SC50 tie-rod cylinder.
Quick checklist
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, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X30 is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centered. For load-holding in a power-off state, an external pilot-operated check valve or a mechanical rod lock must be added to the circuit.
