The AirTAC SC50 Standard Cylinder SC50X735S is a genuine double-acting standard air cylinder with a Ø50mm bore and 735mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X735S is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). With a 50 mm bore and a 735 mm stroke, this model is configured with a built-in magnet, enabling direct mounting of CMSG, DMSG, or EMSG sensors for end-of-stroke detection without external brackets.
This tie-rod cylinder features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 port connections. The adjustable air cushion at each end provides a 21 mm deceleration zone, effectively reducing impact noise and vibration. Its body length A is 150 mm, and the total extended length reaches approximately 885 mm, making it well-suited for medium-force linear transfer tasks.

Provides 982 N of force at 0.5 MPa for pressing components into fixtures or sliding tooling plates on linear guides. The built-in magnet allows sensor confirmation of full extension and retraction.
The 735 mm stroke actuates a diverter arm on a conveyor line. Adjustable cushioning softens the stop at each end, protecting the gate mechanism and reducing noise in high-cycle sorting operations.
Moves a stop plate or aligning arm across a pallet station. The long stroke spans the pallet width, while the magnetic piston enables interlock signals to confirm the arm is clear before indexing the conveyor.
Choose the SC50 bore for applications requiring around 982 N of force at standard plant pressure. If your load demands more thrust, stepping up to the SC63 bore provides 1559 N at 0.5 MPa. For lighter, faster cycling, the SC40 bore offers 628 N. At a 735 mm stroke, the 20 mm rod is extended significantly; ensure the load is guided externally to prevent rod bending and premature bearing wear from side forces.
For a direct replacement, match these five attributes: 50 mm bore, 735 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting configuration. This cylinder is not dimensionally interchangeable with ISO 15552 profiles; it is designed as a direct fit for AirTAC SC tie-rod series installations.
Quick checklist
At 0.7 MPa operating pressure, the theoretical push force is 1374 N, and the pull force on the return stroke is 1155 N. For dynamic applications, we recommend sizing at 50-70% of these theoretical values to account for friction and load variations.
Yes. The -S suffix indicates a magnet is built into the piston. This allows you to clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without any additional mounting hardware.
