The AirTAC SC50 Standard Cylinder SC50X820S is a genuine double-acting standard air cylinder with a Ø50mm bore and 820mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X820S is a double-acting single-rod pneumatic cylinder delivering 1374 N of push force at 0.7 MPa (1767 N at the 0.9 MPa maximum operating pressure). Its 50 mm bore and 820 mm stroke suit medium-force linear tasks where the extended length must reach deep into a fixture or machine frame.
A built-in magnet (-S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The cylinder uses a 20 mm diameter piston rod with an M16x1.5 male thread, PT1/4 ports, and an adjustable air cushion (21 mm length) to decelerate the piston quietly at each end of stroke.

The 820 mm stroke reaches across wide conveyors to actuate a stop or diverter gate. The built-in magnet confirms the gate is fully retracted or extended, preventing collisions.
Delivers 1767 N of clamping force at 0.9 MPa for holding workpieces during machining or welding. Sensor feedback verifies clamp engagement before the cycle starts.
Pushes cartons or totes off a wide roller bed onto a take-away line. The long 820 mm stroke clears the full bed width, and the magnet signals end-of-stroke to the PLC.
Choose the SC50 bore when your application needs roughly 982 N push at 0.5 MPa. If you require more force, step up to the SC63 (1559 N push at 0.5 MPa); for a lighter, more compact solution, the SC40 provides 628 N push at 0.5 MPa. For this 820 mm stroke, be aware that the unsupported 20 mm rod can bend under side load—consider an external linear guide or a guided cylinder if the load is not purely axial.
To replace an existing SC50X820S, match five points: 50 mm bore, 820 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting configuration. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with ISO 15552 cylinders.
Quick checklist
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At 0.7 MPa push force is 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf. These values assume clean, filtered air at 40 µm and a standard double-acting circuit.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip onto the barrel tie-rods. This lets you detect piston position anywhere along the 820 mm stroke without mechanical switches.
