The AirTAC SC50 Standard Cylinder SC50X720S 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 AirTAC SC50X720S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and 720 mm stroke, delivering 982 N of push force at 0.5 MPa (1767 N at the maximum operating pressure of 0.9 MPa). Its built-in magnet (-S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact position feedback.
The 20 mm diameter piston rod and PT1/4 ports provide a robust fluid connection, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly. With a body length A of 150 mm, the total extended length is approximately 870 mm. This cylinder operates on filtered air (40 µm) from -20 to +70 °C with standard TPU/NBR seals.

The 720 mm stroke pushes components across a conveyor or between workstations. The built-in magnet enables end-of-stroke and mid-stroke position sensing for automated sortation logic.
Delivers up to 1767 N of clamping force at 0.9 MPa for holding workpieces during welding, gluing, or CNC machining. Sensor feedback confirms the clamp is fully engaged before the cycle starts.
Long 720 mm reach pushes bins, boxes, or layers onto a pallet. The adjustable cushion absorbs kinetic energy smoothly, reducing noise and mechanical shock at the end of the stroke.
With 982 N of force at 0.5 MPa, the SC50 suits moderate clamping and transfer tasks. If your application needs more force, the SC63 bore steps up to 1559 N push at the same pressure; for a lighter, faster actuator, the SC40 provides 628 N. For this 720 mm stroke, ensure the rod is not subjected to side loading—long, unsupported rods can bend under lateral force. Use an external guide or a guided cylinder if side loads are present.
For a direct replacement, match five points: 50 mm bore, 720 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC50 of the same configuration.
Quick checklist
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At 0.7 MPa push force is 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.
No. The SC50X720S is a double-acting cylinder and will not hold position if pressure is lost or the directional valve is centered—the piston can drift. To safely hold a load without live pressure, you must add a pilot-operated check valve, an external rod lock, or a mechanical brake.
