The AirTAC SC50 Standard Cylinder SC50X815S is a genuine double-acting standard air cylinder with a Ø50mm bore and 815mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X815S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa) from its 50 mm bore. With an 815 mm stroke, it suits long-reach transfer and positioning tasks, while the built-in magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the barrel for rod-position feedback.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston near stroke end to reduce impact. Body length A is 150 mm, giving an approximate extended length of 965 mm. Operating pressure is 0.15-1.0 MPa with TPU seals rated for -20 to +70 °C.

The 815 mm stroke moves components between distant conveyor stations. The built-in magnet enables end-of-stroke sensing for automated sequencing.
982 N of force at 0.5 MPa secures workpieces in machining fixtures. CMSG sensors confirm clamp/unclamp status for interlocked machine safety.
Operates diverter gates on material-handling lines. The long stroke provides the throw needed, while magnetic sensors verify gate position.
For lighter loads, the 40 mm bore SC40 series provides 628 N at 0.5 MPa; for heavier demands, step up to the 63 mm bore SC63 delivering 1559 N. At 815 mm stroke, the 20 mm rod is susceptible to bending under side load—use an external guide or linear rail to protect the rod bearing. When replacing, match bore (50 mm), stroke (815 mm), PT port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting configuration.
Quick checklist
At 0.5 MPa, push force is 982 N and pull force is 825 N. At 0.7 MPa, push reaches 1374 N. The maximum theoretical force at 1.0 MPa is 200 kgf (1960 N push).
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the barrel for non-contact position detection.
