The AirTAC SC50 Standard Cylinder SC50X280SN is a genuine double-acting standard air cylinder with a Ø50mm bore and 280mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X280SN is a 50 mm bore, 280 mm stroke double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise position feedback. The NBR seal (-N) offers dependable performance in standard industrial environments, and the PT1/4 port thread ensures straightforward pneumatic connection.

The 280 mm stroke and sensor-ready magnet make this cylinder ideal for diverting packages on conveyor lines, with position confirmation at each end of travel.
Delivers 982 N of clamping force at standard line pressure, suitable for holding workpieces in CNC fixtures or assembly jigs with NBR seal durability.
Pushes boxes or trays onto pallets with a controlled 280 mm linear stroke, using the adjustable cushion to minimize impact and noise at full extension.
For applications needing slightly more force, stepping up to a 63 mm bore provides 1559 N at 0.5 MPa. At 280 mm stroke, the rod is well-supported within standard limits, but avoid direct side loads without an external guide to prevent rod bending and premature seal wear.
When replacing this cylinder, match five key points: 50 mm bore, 280 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the NBR seal material. This ensures a direct fit with existing sensor and control setups.
Quick checklist
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston, allowing AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the cylinder barrel for end-of-stroke detection.
