The AirTAC Airtac SC Standard Cylinders SC63X75 is a genuine double-acting standard air cylinder with a Ø63mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC63X75 is a double-acting tie-rod cylinder with a 63 mm bore and a short 75 mm stroke, sized for compact push-and-pull work rather than long travel. At 0.5 MPa it develops about 1559 N on extension and 1402 N on retraction; pushed to 0.9 MPa the same barrel reaches 2805 N. The 20 mm rod and 28 mm adjustable cushions give this bore a solid margin against rod buckling at short stroke while keeping end-of-stroke impact under control.
Because the stroke is only 75 mm, the assembled cylinder measures roughly 228 mm from rod-end to cap (body length A of 153 mm plus stroke), so it fits where a longer actuator will not. Ports are PT1/4, the rod thread is M16x1.5, and the standard TPU seals cover -20 to +70 C with filtered air. This listing is for the basic (unbracketed) body in the standard SC single-rod configuration.

Fixtures and jigs that need a firm 1559 N clamp over just 75 mm of travel, where a long-stroke cylinder would waste space and cycle time.
Pushing parts off a nest or driving a light punch: 2182 N at 0.7 MPa with 28 mm cushions softens the strike without slowing the cycle.
Raising stoppers or kicking product between conveyor lanes, where the compact 228 mm body length clears tight guarding.
At 75 mm stroke you are in short-stroke territory: confirm the 75 mm travel covers your tooling clearance before stepping up to a 100 or 125 mm standard stroke. On force, the 63 mm bore gives 1559 N at 0.5 MPa - step down to a 50 mm bore (982 N) for lighter clamping, or up to an 80 mm bore (2513 N) if your load margin is thin. For strokes beyond 300 mm or any meaningful side load, move to an external guide or a guided cylinder rather than relying on the rod bearing alone.
Replacing an existing SC unit? Match all five points: bore (63), stroke (75), port thread (PT here, or G if the old code ends in G), mounting accessory (this one is basic, so no LB/FA/FB/CA/CB/TC bracket), and magnet (no -S suffix means no position sensing). A tie-rod SC is shorter than an ISO 15552 cylinder, so it is not a dimensional direct for ISO profile actuators.
Quick checklist
At 0.5 MPa it delivers about 1559 N extending and 1402 N retracting. At the full 0.7 MPa working pressure expect roughly 2182 N, and the theoretical peak at 0.9 MPa is 2805 N. Always size with a safety margin - a practical working load is well below the theoretical figure.
Match five things against your old cylinder: 63 mm bore, 75 mm stroke, PT1/4 port thread (G thread is a separate suffix), the mounting arrangement (this SC63X75 is basic with no bracket - foot, flange, clevis and trunnion accessories are ordered separately as F-SC63 codes), and whether a magnet (-S) is needed for CMSG/DMSG/EMSG sensors. Note the SC is not dimensionally interchangeable with ISO 15552 profile cylinders.
