The AirTAC SC50 Standard Cylinder SC50X740S is a genuine double-acting standard air cylinder with a Ø50mm bore and 740mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X740S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and a 740 mm stroke, factory-equipped with a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors. Its 20 mm diameter piston rod and PT1/4 ports supply a push force of 1767 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-range actuator.
This model uses the standard TPU/NBR seals for a working temperature range of -20 to +70 °C and features an adjustable air cushion (21 mm length) to decelerate the piston quietly at end of travel. With a body length A of 150 mm, the total extended length reaches approximately 890 mm, suitable for long linear transfer tasks where position feedback is required.

The 740 mm stroke and 1767 N of force at 0.9 MPa move heavy trays or pallets between conveyor lanes. The built-in magnet lets CMSG sensors confirm end-of-stroke position at both ends.
With 1374 N of push at 0.7 MPa, this cylinder powers the horizontal axis of a gantry. The magnet enables mid-stroke sensing for multi-position stops when paired with a 3-position valve.
Delivers 982 N at 0.5 MPa to shift a diverter gate in a material handling chute. The long 740 mm stroke provides the clearance needed for wide conveyor merges.
The SC50 bore provides 982 N of push force at 0.5 MPa. If your load requires more force, stepping up to the SC63 bore delivers 1559 N at the same pressure. For a lighter, more compact solution, the SC40 bore offers 628 N. At a 740 mm stroke, the unsupported rod length is significant; side loads must be avoided to prevent rod bending and premature bearing wear. Use an external linear guide or a guided cylinder if the load is not perfectly axial.
For a direct replacement, match these five points: 50 mm bore, 740 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix) for sensor compatibility, and the basic (no-bracket) mounting configuration. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa operating pressure, the SC50 bore generates a theoretical push force of 1374 N (extending) and a pull force of 825 N (retracting). The maximum push force at 0.9 MPa is 1767 N.
Ensure the replacement matches all five key specifications: 50 mm bore, 740 mm stroke, PT1/4 pneumatic ports, the -S magnet option for barrel-mounted sensors, and the basic mounting style. The SC series is a tie-rod cylinder; it is not interchangeable with ISO 15552 profile cylinders.
