The AirTAC Airtac SC Standard Cylinders SC63X660S is a genuine double-acting standard air cylinder with a Ø63mm bore and 660mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC63X660S is a double-acting tie-rod cylinder with a 63 mm bore and a long 660 mm stroke, delivering roughly 1559 N of push force at 0.5 MPa and 2182 N at 0.7 MPa. The -S suffix means a magnet is built into the piston, so CMSG, DMSG or EMSG position sensors clamp directly onto the barrel for end-of-stroke or mid-stroke signalling without any external brackets.
With the rod extended, the cylinder measures approximately 813 mm overall (153 mm body length A plus 660 mm stroke). The 20 mm rod is carried in a generous 28 mm adjustable cushion at each end, which decelerates the piston near stroke end to soften impact on long travel moves. Ports are PT1/4 and the rod thread is M16x1.5.

The 660 mm stroke sweeps wide conveyor lanes or diverts products across the full belt width, with the built-in magnet confirming retract position via a barrel-mounted sensor.
Around 1559 N of push at 0.5 MPa raises and lowers light fixtures, gates and test rigs over a long vertical travel; add an external guide for anything with side load.
Drives long-travel machine slides and workpiece clamps where 2182 N at 0.7 MPa gives ample margin, and the 28 mm adjustable cushions tame end-of-stroke shock.
At 660 mm of stroke you are well inside the 1500 mm maximum standard stroke for the 63 mm bore, so no made-to-order build is needed. If your load needs more than about 1559 N at 0.5 MPa, step up to the SC80 bore (2513 N at 0.5 MPa); if the force is comfortably under the SC50's 982 N at 0.5 MPa, the smaller bore saves air and money.
A 660 mm stroke on a 20 mm rod means a long, relatively slender rod column: manage side load with an external guide or a guided cylinder, and align the load axis carefully to avoid rod-bearing wear. When replacing an existing unit, match all five points: 63 mm bore, 660 mm stroke, PT1/4 port thread (or G variant), mounting accessory, and the -S magnet option.
Quick checklist
At 0.5 MPa the 63 mm bore gives about 1559 N on the push stroke and 1402 N on the pull stroke (the 20 mm rod reduces pull area). At 0.7 MPa push force rises to roughly 2182 N, and at the 0.9 MPa operating ceiling it reaches about 2805 N. Theoretical maximum force at 1.0 MPa is 318 kgf.
With 660 mm of travel on a 20 mm rod, side load is the main risk: it bends the rod and wears the rod bearing. Mount the load on an external guide or use a guided cylinder, keep the thrust axis aligned, and use the adjustable cushions to soften stroke-end impact. Note the SC holds no position when air is lost - add a mechanical lock or pilot-operated check valve if the load must be held without pressure.
