The AirTAC SC50 Standard Cylinder SC50X800SFA is a genuine double-acting standard air cylinder with a Ø50mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X800SFA is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), built around a 50 mm bore and an 800 mm stroke. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration, making it suitable for medium-duty linear tasks that require a long working reach.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise end-of-stroke or mid-stroke position feedback. The front rectangular flange (FA, accessory F-SC50FA) allows rigid panel or bulkhead mounting, while the standard PT1/4 port threads and TPU seals keep it compatible with common filtered-air systems operating from -20 to +70 °C.

The 800 mm stroke and 982 N push force move components between distant conveyor stations or indexing tables, with magnetic sensors confirming full extension and retraction.
Front-flange mounting secures the cylinder to a frame, while the long stroke actuates a material diverter gate or chute flap in packaging and sortation lines.
Delivers consistent clamping force for large-part assembly or welding fixtures, with the adjustable cushion absorbing impact energy at the end of the 800 mm travel.
For applications needing more force, stepping up to the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa. If a shorter, more compact build is acceptable, the 40 mm bore SC40 delivers 628 N at the same pressure. With an 800 mm stroke, the extended 20 mm rod is susceptible to bending under side loads—always guide the load externally or use a guided cylinder if lateral forces are present. When replacing an existing unit, match these five points exactly: 50 mm bore, 800 mm stroke, PT1/4 port thread, front flange FA mounting, and the built-in magnet (-S) for sensor compatibility.
Quick checklist
At 0.5 MPa the cylinder provides 982 N pushing and 825 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel to detect piston position without external brackets.
