The AirTAC SC50 Standard Cylinder SC50X275S is a genuine double-acting standard air cylinder with a Ø50mm bore and 275mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X275S is a double-acting AirTAC tie-rod cylinder with a 50 mm bore and 275 mm stroke, factory-equipped with a built-in magnet. The magnet allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing — ideal for automated sequences where end-of-stroke or mid-stroke confirmation is required.
At 0.5 MPa this model delivers 982 N pushing and 825 N pulling, rising to 1767 N push at the 0.9 MPa maximum operating pressure. The 20 mm diameter piston rod carries an M16x1.5 male thread, and the adjustable air cushion (21 mm length) decelerates the piston smoothly at each end. The body length A is 150 mm, giving a total extended length of approximately 425 mm.

The 275 mm stroke and sensor-ready magnet make this cylinder a strong fit for pusher and diverter stations on packaging or assembly conveyors, where mid-stroke sensor flags confirm product position before the next cycle.
With 982 N of clamping force at standard line pressure, the SC50X275S holds workpieces securely in CNC machining fixtures or welding jigs. The built-in magnet enables clamp-open and clamp-closed verification sensors.
Used to open and close chute gates or hopper doors in material handling, the 275 mm stroke provides ample travel. Magnetic sensors confirm the gate is fully open or sealed shut, preventing spillage and improving process safety.
For applications needing more force, the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa; for a lighter, more compact solution the 40 mm bore offers 628 N. The SC50X275S is a standard-stroke model (bore 50 max standard stroke is 1200 mm) with PT1/4 ports. When replacing an existing cylinder, match five points: 50 mm bore, 275 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic mounting configuration. Because the 275 mm stroke is moderately long for a 20 mm rod, avoid unsupported side loads — if the load is not guided externally, consider adding a linear guide or switching to a guided-cylinder assembly to protect the rod bearing from bending stress.
Quick checklist
At 0.5 MPa air pressure the cylinder produces 982 N extending (push) and 825 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf. All forces assume clean, filtered air at 40 µm and a stable supply pressure.
Yes. The -S suffix indicates a built-in magnet inside the piston, so AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors clip directly onto the barrel tie-rods. No external brackets or target flags are needed. If your application does not require sensors, the standard SC50X200 (without -S) offers the same mechanical performance.
