The AirTAC Airtac SC Standard Cylinders SC63X600 is a genuine double-acting standard air cylinder with a Ø63mm bore and 600mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC63X600 is a double-acting tie-rod cylinder with a 63 mm bore and a long 600 mm stroke. 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. The 20 mm rod carries that force over the full travel, and the 28 mm adjustable cushion decelerates the piston at each end of the 600 mm run.
This is a long-stroke build: body length A is 153 mm, so the fully extended length is roughly 753 mm. Operating pressure spans 0.15-1.0 MPa with 1.5 MPa proof pressure, fluid is air filtered to 40 um, and the TPU seal set works from -20 to +70 C. Ports are PT1/4 and the rod thread is M16x1.5.

With 600 mm of travel and 1559 N of push at 0.5 MPa, this cylinder swings or lifts product across wide conveyor lanes in a single stroke.
The 63 mm bore raises medium-weight assemblies through a 600 mm vertical run; the 28 mm adjustable cushion softens the stop at both ends. Add a mechanical lock or pilot-operated check valve if the load must hold when air is lost.
Push-pull duty on machine slides, doors and gates across a long span, running at 30-800 mm/s on filtered 40 um air.
At 600 mm stroke this SC63X600 sits in the mid-range of the 63 mm bore's 1500 mm standard stroke limit, so it is a catalogue item, not a made-to-order length. If 1559 N at 0.5 MPa feels marginal for your load, step up to the SC80, which pushes about 2513 N at the same pressure; if you are overspec, the SC50 gives roughly 982 N and saves envelope. A 600 mm unsupported rod is exposed to bending under side load, so mount the load on an external guide or specify a guided cylinder rather than letting the rod bearing take lateral force.
Replacing an existing unit? Match all five points: 63 mm bore, 600 mm stroke, PT1/4 port thread, the same mounting accessory, and whether the old cylinder carries the -S magnet option. This SC is a tie-rod cylinder that runs shorter than an ISO 15552 body, so it is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa it delivers 1559 N extending and 1402 N retracting. At 0.7 MPa extension force is 2182 N, and at the 0.9 MPa maximum operating pressure it reaches 2805 N. The theoretical maximum is about 318 kgf at 1.0 MPa.
Yes, in most cases. A 600 mm unsupported rod will bend under side load, so carry the load on an external guide or choose a guided cylinder instead of loading the rod bearing laterally. For a like-for-like replacement, match bore, stroke, PT1/4 port thread, mounting accessory and the magnet option.
