The AirTAC Airtac SC Standard Cylinders SC50X470T is a genuine double-acting standard air cylinder with a Ø50mm bore and 470mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X470T is a double-acting tie-rod cylinder with NPT 1/4 tapered ports, the North-American pipe thread that seals on the thread itself, so it mates directly with existing NPT fittings and manifolds without adaptors. With a 470 mm stroke on a 50 mm bore it reaches about 982 N at 0.5 MPa (around 200 kgf theoretical max), comfortably covering mid-duty push, lift and eject tasks on imperial-plumbed machinery. A 20 mm hardened rod and 21 mm adjustable cushions help it run 30-800 mm/s without harsh end-of-stroke impact. Body length A is 150 mm, so fully extended the cylinder measures roughly 620 mm front to rear before the rod is included. Across the 470 mm stroke the piston sweeps 582 cm3 on the push side, so size your FRL and valve flow for a cylinder this length, not just this bore. Cushion needles on both ends let you trim deceleration independently for extend and retract.

At 982 N at 0.5 MPa the 50 mm bore kicks pallets or totes onto a side lane; the 470 mm stroke clears a wide divert bed, and NPT ports connect to the line's existing imperial plumbing.
Cardboard and packaging waste bins need mid-range force over a long travel; 1767 N at 0.9 MPa gives headroom, and the 21 mm cushions soften the strike at full compression.
Raising a die cart or fixture riser through 470 mm of travel suits this stroke exactly; external guide rails carry the off-centre load the bare rod should not see.
Size both ways against neighbours: the SC32 gives about 402 N at 0.5 MPa if your load is under roughly 40 kg, while stepping up to SC63 raises force to about 1559 N at 0.5 MPa if duty cycles or side conditions tighten. Stay at bore 50 when 0.5 MPa working pressure and a moderate duty cycle match your load with margin. A 470 mm stroke means a long, relatively slender rod: unsupported side load will bend the rod and wear the front bearing prematurely. Keep the load guided externally, or specify a guided cylinder version, and align the thrust axis precisely at installation. For a like-for-like replacement, match five points: 50 mm bore, 470 mm stroke, NPT 1/4 port thread, the mounting accessory (LB, FA, FB, CA, CB, TC or TCM1), and the magnet option (-S if sensors are used).
Quick checklist
At 0.5 MPa the bore-50 piston pushes with about 982 N and pulls with about 825 N (the rod side loses area). At 0.9 MPa push force reaches about 1767 N, and the theoretical maximum at 1.0 MPa is roughly 200 kgf. Working pressure range is 0.15-1.0 MPa with 1.5 MPa proof pressure, so always size the load below the 0.5 MPa figures if your plant runs at nominal line pressure.
Match five things for a drop-in swap: 50 mm bore, 470 mm stroke, NPT 1/4 port thread, mounting accessory code, and whether a magnet (-S) is fitted. The NPT thread matters because this T-suffix variant is the imperial-port version for North-American plumbing; the standard SC50 uses tapered PT (Rc) ports, and a G/BSPP version is a separate SKU. NPT seals on the tapered threads with sealant or tape, not on a face washer, so never substitute the thread variant on an existing manifold without checking the ports.
