The AirTAC SC50 Standard Cylinder SC50X520S is a genuine double-acting standard air cylinder with a Ø50mm bore and 520mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X520S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and an extended 520 mm stroke, delivering 982 N of push force at 0.5 MPa. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration, while the built-in magnet enables direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors for end-of-stroke detection without external brackets.
This non-standard stroke length exceeds the typical 1200 mm maximum for the 50 bore, making it a made-to-order configuration for applications requiring precise mid-range linear travel. The cylinder body length A is 150 mm, resulting in a total extended length of approximately 670 mm, and it uses PT1/4 ports with an M16x1.5 rod thread as standard.

The 520 mm stroke and 1767 N peak force at 0.9 MPa make it effective for raising and lowering conveyor line stops or diverters, where the built-in magnet provides clean sensor feedback to the PLC.
Delivers 982 N at 0.5 MPa for secure workpiece clamping in CNC or welding fixtures. The -S magnet allows compact CMSG sensor mounting to confirm clamp engagement without adding bulky external flags.
Ideal for a long-stroke case packer pusher arm, moving products 520 mm across a conveyor. The adjustable cushion absorbs impact at the end of travel, protecting the carton and reducing noise in high-cycle packaging lines.
Select the SC50 bore when your application needs around 982 N of force at standard plant pressure; if you require less force and a lighter assembly, step down to the SC40 (628 N push at 0.5 MPa). For strokes of 300 mm or more, like this 520 mm unit, evaluate side-load conditions carefully—long, unsupported 20 mm rods are susceptible to bending under lateral force. Use an external linear guide or a guided cylinder to protect the rod bearing and ensure consistent cycle life.
To replace an existing cylinder, match five points: 50 mm bore, 520 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting configuration. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC series or equivalent tie-rod designs.
Quick checklist
At 0.7 MPa (7 bar) operating pressure, the SC50 cylinder produces a theoretical push force of 1374 N. At the maximum operating pressure of 0.9 MPa, it generates 1767 N. Always apply a safety factor for real-world dynamic loads.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than a comparable ISO 15552 profile cylinder. It will not drop into the same mounting footprint. Use it to replace another AirTAC SC50 tie-rod cylinder with matching stroke, port, and magnet options, or verify all mounting dimensions against your machine before ordering.
