The AirTAC SC50 Standard Cylinder SC50X560S is a genuine double-acting standard air cylinder with a Ø50mm bore and 560mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X560S is a double-acting pneumatic cylinder delivering 1374 N of push force at 0.7 MPa, built on a 50 mm bore with a 20 mm diameter piston rod. Its 560 mm stroke exceeds the standard 1200 mm maximum for this bore, making it a non-standard length order for applications needing extended reach without stepping up to a larger frame size.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for contactless position feedback. The adjustable air cushion at each end decelerates the 20 mm rod smoothly, with a 21 mm cushion length and PT1/4 ports for standard pneumatic plumbing.

The 560 mm stroke pushes a stop gate across a wide conveyor lane. The built-in magnet confirms gate position at each end, preventing collisions in automated sortation.
Extends a clamp arm deep into a welding fixture. The 1374 N force at 0.7 MPa holds the workpiece rigidly, while cushioning reduces impact vibration at full extension.
Transfers pallets between roller beds with a 560 mm stroke. Magnetic sensors signal the PLC when the transfer arm is fully retracted, enabling safe cross-traffic sequencing.
Choose the SC50 when your load requires around 982 N of push at 0.5 MPa. If you need more force, the SC63 bore provides 1559 N at the same pressure, while the SC40 offers a lighter 628 N alternative. For this 560 mm stroke, the unsupported rod length demands attention: side loads or high-speed cycling can induce bending stress on the 20 mm rod, so consider an external linear guide or a guided cylinder configuration.
To replace an existing unit, match five key points: 50 mm bore, 560 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting style. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
Quick checklist
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At 0.7 MPa push force rises to 1374 N. The maximum operating pressure of 1.0 MPa yields 1767 N of push force (200 kgf theoretical).
No. A 20 mm rod extended 560 mm is vulnerable to bending under side load. The rod bearing is designed for axial thrust, not lateral forces. Always use an external guide rail or rod-alignment coupler for any off-axis loading to prevent premature seal and bearing wear.
