The AirTAC Airtac SC Standard Cylinders SC63X80 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 AirTAC SC63X80 is a compact tie-rod, double-acting pneumatic cylinder with a 63 mm bore and a short 80 mm stroke. At the common 0.5 MPa working pressure it delivers about 1559 N on extension and 1402 N on retraction, rising to 2805 N at the 0.9 MPa maximum. The 20 mm hardened rod and 28 mm adjustable cushion give this short-stroke size a solid margin for fast, repetitive clamping and pressing cycles.
With a body length A of 153 mm, the fully extended length is roughly 233 mm, keeping the envelope tight for machines where every millimetre of stroke counts. Ports are PT1/4, the rod thread is M16x1.5, and the standard TPU seal set operates from -20 to +70 C on filtered air. This is a genuine AirTAC SC-series cylinder, not an ISO 15552 profile unit, so it sits shorter than ISO-sized equivalents.

The 80 mm stroke and 1559 N push force at 0.5 MPa suit fixture clamps and swing clamps that need quick, repeatable hold-down on jigs and welding fixtures.
Compact 233 mm extended length lets the SC63X80 drive ejectors, part kickers and indexing pins inside tight machine frames where longer cylinders will not fit.
With 1402 N of retraction force and a 28 mm adjustable cushion, this cylinder handles diverting and pushing small cartons at speeds up to 800 mm/s.
Choose the SC63X80 when your load needs roughly 1559 N at 0.5 MPa over a short 80 mm travel. If your force budget is under about 982 N, the 50 mm bore (982 N push at 0.5 MPa) saves space; if you need more than 2182 N at 0.7 MPa, step up to the 80 mm bore (2513 N at 0.5 MPa). At 80 mm stroke the rod is well supported, so side loads stay modest, but an external guide is still wise for any off-axis tooling.
Replacing an existing unit? Match all five points: 63 mm bore, 80 mm stroke, PT1/4 port thread (or specify G), the same mounting accessory code, and the same magnet option. This SC63X80 is a basic-mount, no-magnet, TPU-sealed, PT-threaded model, so it only swaps directly with another AirTAC SC tie-rod cylinder built to the same configuration.
Quick checklist
At 0.5 MPa the 63 mm bore gives about 1559 N pushing and 1402 N pulling. At 0.7 MPa push force is 2182 N, and at the 0.9 MPa maximum operating pressure it reaches 2805 N. Theoretical maximum force at 1.0 MPa is 318 kgf.
The SC is a tie-rod cylinder, not an ISO 15552 profile cylinder, so it is shorter than ISO-sized units and not dimensionally interchangeable with them. For a like-for-like swap, match the 63 mm bore, 80 mm stroke, PT1/4 port thread, mounting accessory and magnet option against another AirTAC SC cylinder.
