The AirTAC Airtac SC Standard Cylinders SC63X800 is a genuine double-acting standard air cylinder with a Ø63mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC63X800 is a double-acting AirTAC SC tie-rod cylinder with a 63 mm bore and a long 800 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 operating pressure. The 20 mm rod and 28 mm adjustable cushions make it a solid choice for long-travel push, lift and index motions.
With the 153 mm body length A, the fully extended length is roughly 953 mm. Ports are PT1/4, the rod thread is M16x1.5, and the standard TPU seals cover a -20 to +70 C temperature range with filtered air at 0.15-1.0 MPa.

Raising chutes, gates and platform sections through 800 mm of travel, where 1559 N at 0.5 MPa handles moderate dead loads. Fit a mechanical lock or pilot-operated check valve if the load must be held with air off.
Pushing product lanes or indexing pallet fixtures along a long travel path, with the 28 mm adjustable cushions decelerating the piston near stroke end to cut impact noise.
Driving a slide or clamp bridge on packaging and assembly machinery, where the 800 mm stroke covers full-open to full-closed positions in one double-acting move.
At 800 mm stroke this cylinder is within the 1500 mm standard stroke limit 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, which produces roughly 2513 N at the same pressure; if you are over-sized, the SC50 gives about 982 N and saves space. Because the 20 mm rod is slender over an 800 mm travel, keep side loads off the rod: use an external guide or a guided cylinder whenever the tooling is not positively guided, and align the mounting so the rod sees pure axial force.
Replacing an existing unit? Match all five points: 63 mm bore, 800 mm stroke, PT1/4 port thread, the same mounting accessory, and the magnet option (-S if the old cylinder carried sensors).
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. Theoretical maximum force at 1.0 MPa is 318 kgf.
Yes, in most cases. The 20 mm rod is unsupported over 800 mm, so side loads will bend it and wear the rod bearing. Mount the cylinder so the load travels purely axially, or add an external guide rail or a guided cylinder to carry any lateral force.
