The AirTAC Airtac SC50 Standard Cylinder SC50X730S is a genuine double-acting standard air cylinder with a Ø50mm bore and 730mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X730S is a double-acting tie-rod cylinder with a 50 mm bore and a 730 mm stroke, delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration at end-of-stroke, making it suitable for medium-duty linear tasks.
This model includes the built-in magnet suffix (-S), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing. The standard PT1/4 port and TPU seals cover a -20 to +70 °C operating range, with a body length A of 150 mm plus the 730 mm stroke.

Pushes or diverts boxes and totes on a conveyor line. The 730 mm stroke reaches across wide belt sections, and the built-in magnet confirms extend/retract position.
Applies 1767 N of clamping force at 0.9 MPa to hold workpieces during machining or welding. The sensor magnet enables interlocked cycle start signals.
Acts as a pneumatic stop or lift gate in pallet-handling systems. The long 730 mm stroke provides ample reach, and the adjustable cushion softens the stop impact.
For a 50 mm bore at 730 mm stroke, the SC50X730S provides 982 N at 0.5 MPa. If the load requires more force, stepping up to a 63 mm bore (SC63) raises push force to 1559 N at the same pressure. At this stroke length, the unsupported rod is subject to bending under side load; use an external linear guide or a guided cylinder if the load is not purely axial.
When replacing an existing cylinder, match five points: 50 mm bore, 730 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting. This tie-rod SC cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with it.
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, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC50X730S is a double-acting cylinder and will not hold position when pressure is exhausted or the directional valve is centered. For load holding, add a pilot-operated check valve or an external mechanical rod lock.
