The AirTAC SC Standard Cylinders SC63X500S is a genuine double-acting standard air cylinder with a Ø63mm bore and 500mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC63X500S is a double-acting AirTAC SC tie-rod cylinder with a 63 mm bore and a long 500 mm stroke, ordered with the -S option so a magnet is built into the piston. 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 maximum operating pressure. The 500 mm stroke is a standard length for this bore, which is rated up to 1500 mm.
The 20 mm rod and 28 mm adjustable cushion give this model a solid margin for longer travel duties, and the extended body length is approximately 653 mm (body length A of 153 mm plus the 500 mm stroke). Ports are PT1/4 with an M16x1.5 rod thread, and the TPU seals cover a -20 to +70 C working range on filtered air at 0.15-1.0 MPa. Because the magnet is built in, CMSG, DMSG or EMSG sensors clamp directly onto the barrel for end-of-stroke or mid-stroke position signals.

With 1559 N of push at 0.5 MPa and 500 mm of travel, this cylinder ejects cartons or totes from wide conveyor lanes in one full stroke.
The built-in magnet lets CMSG or EMSG sensors confirm clamp and release positions on fixtures, while the 63 mm bore holds 2182 N at 0.7 MPa.
A 20 mm rod and 1402 N of pull force at 0.5 MPa suit vertical lifting of moderate loads over a 500 mm lift; add an external guide to keep the rod straight.
Choose the SC63X500S when your load sits between the SC50 class (982 N push at 0.5 MPa) and the SC80 class (2513 N push at 0.5 MPa); step down to SC50 for lighter duty or up to SC80 if you need over 2000 N at half pressure. At 500 mm of travel the rod is well exposed, so keep side loads off the piston rod - use an external guide or a guided cylinder if the tooling cannot be aligned, since a long unsupported 20 mm rod will bend under lateral force.
Replacing an existing unit? Match all five points: 63 mm bore, 500 mm stroke, PT1/4 port thread (or specify G), the same mounting accessory, and the -S magnet if sensors are fitted. This cylinder is a tie-rod design, not an ISO 15552 profile cylinder, so it is shorter than ISO 15552 dimensions and is not a direct for them - match against another AirTAC SC of the same specification instead.
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 roughly 2182 N, and at the 0.9 MPa maximum operating pressure it reaches about 2805 N. The theoretical maximum at 1.0 MPa is around 318 kgf for this 63 mm bore.
The cylinder itself is not guided, and at 500 mm the exposed 20 mm rod is prone to bending if any side load is present. Mount the cylinder so the load axis is pure push-pull, or add an external guide or a guided cylinder for the tooling. Also note the adjustable cushion only decelerates the piston near stroke end - it does not lock or hold the load if air pressure is lost.
