The AirTAC SC50 Standard Cylinder SC50X350 is a genuine double-acting standard air cylinder with a Ø50mm bore and 350mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X350 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 350 mm stroke, this model suits medium-force linear tasks where a compact footprint is required—the SC body is shorter than an equivalent ISO 15552 cylinder.
This configuration features a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 port connections. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. The standard TPU seals provide reliable operation from -20 to +70 °C.

Actuates a diverter gate on a packaging conveyor with 982 N of push force at standard plant air pressure, reliably sorting cartons by size or destination.
Provides consistent 350 mm stroke clamping for woodworking or metal fab jigs, holding workpieces securely during routing, drilling, or welding operations.
Opens and closes a discharge door on a seed or aggregate hopper, using the adjustable cushion to soften the stop at each end of the 350 mm travel.
For applications needing slightly less force, the 40 mm bore SC40 series produces 628 N at 0.5 MPa, while stepping up to the 63 mm bore SC63 yields 1559 N at the same pressure. At a 350 mm stroke, ensure side loads are minimized; long unsupported piston rods can experience bending under lateral force. Consider an external linear guide or a guided cylinder if the load is not perfectly axial.
To replace an existing cylinder, match five key points: 50 mm bore, 350 mm stroke, PT1/4 port thread, the specific mounting accessory (this is a basic body, so confirm if feet or flanges are needed), and the absence of a built-in magnet. This model uses the standard PT thread and TPU seals.
Quick checklist
At 0.5 MPa 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 reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X350 is a double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. For load holding without live pressure, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
