The AirTAC Airtac SC Standard Cylinders SC63X75S 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 SC63X75S is a double-acting AirTAC SC tie-rod cylinder with a 63 mm bore and a short 75 mm stroke. At 0.5 MPa it delivers about 1559 N on extension and 1402 N on retraction, rising to 2805 N at the 0.9 MPa peak of its 0.15-1.0 MPa working range. The 20 mm rod and 28 mm adjustable cushion make it a solid pick for short, punchy clamping and indexing moves.
The S suffix means a magnet is built into the piston, so CMSG, DMSG or EMSG sensors clamp straight onto the barrel for end-of-stroke or mid-stroke signalling. With a 153 mm body length A, the extended length is roughly 228 mm, keeping the footprint tight on compact fixtures. Ports are PT1/4 and the standard TPU seals cover -20 to +70 C.

1559 N of push at 0.5 MPa over just 75 mm is ideal for hold-down clamps on machining and assembly fixtures, with the magnet confirming the clamp is fully seated.
A quick 75 mm kick clears parts off chutes or nests; the 28 mm adjustable cushion softens the stop so the mechanism is not hammered at each cycle.
Use the magnet and a CMSG sensor to time pusher actions on conveyor lines, diverting or stopping product with repeatable, sensed positioning.
At 75 mm stroke this cylinder suits short-travel work where position feedback matters. If you need more muscle, step up to the 80 mm bore, which pushes about 2513 N at 0.5 MPa; if 1559 N is generous for your load, the 50 mm bore (about 982 N at 0.5 MPa) saves space and air. The 75 mm stroke is well inside the 1500 mm maximum for this bore, so side-load bending is not a concern, but keep external side forces off the rod or use a guided arrangement.
Replacing an existing unit? Match all five points: 63 mm bore, 75 mm stroke, PT1/4 port thread (PT, not G), mounting accessory, and the -S magnet option. This code has no mounting bracket, so order any F-SC63 accessory separately if your machine needs one.
Quick checklist
At 0.5 MPa it pushes with about 1559 N and pulls with about 1402 N. At 0.7 MPa the 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 around 318 kgf.
S means a magnet is built into the piston. CMSG, DMSG and EMSG reed or solid-state sensors clamp onto the barrel to signal extend, retract or intermediate positions. When replacing an older unit, keep the -S suffix so your existing sensors still work.
