The AirTAC SC50 Standard Cylinder SC50X775S is a genuine double-acting standard air cylinder with a Ø50mm bore and 775mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X775S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the 0.9 MPa maximum operating pressure. With a 50 mm bore and a 20 mm piston rod, it handles a 775 mm stroke within the standard stroke range for this bore size.
The built-in magnet (suffix -S) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact position sensing. The cylinder body length A is 150 mm, giving an approximate extended length of 925 mm. TPU seals provide a standard operating temperature range of -20 to +70 °C.

The 775 mm stroke and built-in position sensing make it ideal for long-reach diverter gates on packaging or sorting conveyors, with sensors confirming open/closed status.
Delivers consistent linear motion for dispensing heads across wide panels. The -S magnet provides end-of-stroke feedback to the PLC for precise cycle control.
With 982 N of force at 0.5 MPa, it reliably pushes finished cases onto pallets. The long 775 mm stroke clears the full conveyor width in a single motion.
Choose the SC50 when your application needs roughly 1000 N at typical plant air pressure; stepping up to the SC63 bore raises force to 1559 N at 0.5 MPa, while the SC40 delivers 628 N. For this 775 mm stroke, ensure the rod is not subjected to side loads—long unsupported strokes can cause rod bearing wear or bending; use an external guide or a guided cylinder if lateral forces are present.
To replace an existing cylinder, match five points: 50 mm bore, 775 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting configuration. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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.
Yes. The -S suffix in SC50X775S indicates a built-in magnet on the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for reliable end-of-stroke or mid-stroke position detection.
