The AirTAC Airtac SC Standard Cylinders SC63X80S is a genuine double-acting standard air cylinder with a Ø63mm bore and 80mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC63X80S is a 63 mm bore, 80 mm stroke double-acting tie-rod cylinder from AirTAC's SC series. At 0.5 MPa it delivers about 1559 N on extension and 1402 N on retraction, rising to 2182 N at 0.7 MPa and 2805 N at the 0.9 MPa peak. The 80 mm stroke suits short, repetitive moves such as clamping, pressing and part ejection, and the compact body keeps the extended length to roughly 233 mm (body length A 153 mm plus the 80 mm stroke).
The S suffix means a magnet is built into the piston, so CMSG, DMSG or EMSG switch sensors clamp directly onto the barrel for end-of-stroke or mid-stroke signalling. Ports are PT1/4, the rod is 20 mm with an M16x1.5 knuckle thread, and the adjustable cushion is 28 mm long to decelerate the piston smoothly at both ends. Speed range is 30-800 mm/s.

Short-stroke clamping of fixtures and jigs, where 1559 N at 0.5 MPa holds parts firmly and the magnet confirms full clamp via a CMSG sensor.
Ejecting stamped or machined parts from a die or nest on an 80 mm kick, with the 28 mm cushion absorbing the impact at stroke end.
Pushing cartons or trays off a conveyor line, with DMSG or EMSG sensors on the barrel signalling extend and retract positions to the PLC.
At 80 mm stroke this cylinder sits in the mid-force band: 1559 N push at 0.5 MPa. Step down to a 50 mm bore (982 N at 0.5 MPa) if space or air consumption matters; step up to an 80 mm bore (2513 N at 0.5 MPa) if the load approaches the 63 mm limit. The 80 mm stroke is well inside the 1500 mm maximum for this bore, so no non-standard order is needed.
Replacement match checklist: same bore (63), same stroke (80), same port thread (PT1/4, PT as standard or G on request), same mounting accessory, and the magnet option (-S) if sensors are used. For side-loaded or guided work, pair the cylinder with external linear guides rather than relying on the rod bearing alone.
Quick checklist
At 0.5 MPa it pushes with about 1559 N and pulls with about 1402 N. At 0.7 MPa push force is 2182 N, and at 0.9 MPa it reaches 2805 N. Theoretical maximum force at 1.0 MPa is roughly 318 kgf. Note the cylinder does not hold position if air pressure is lost - use a mechanical lock or pilot-operated check valve where load holding is required.
S indicates a built-in piston magnet, allowing CMSG, DMSG or EMSG position sensors to clamp onto the cylinder barrel for stroke-end or intermediate position detection. Otherwise the model is a standard SC 63 mm bore: 80 mm stroke, PT1/4 ports, TPU seals rated -20 to +70 C, and basic mounting without brackets.
