The AirTAC Airtac SC Standard Cylinders SC50X470ST 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 SC50X470ST is a double-acting tie-rod cylinder with NPT 1/4 in tapered ports, sized for North-American pipe fittings, and a built-in magnet (-S) for CMSG, DMSG or EMSG switch position feedback. Its 470 mm stroke gives a long working sweep - about 620 mm overall extended length (body length A is 150 mm) - while the 50 mm bore pushes 982 N at 0.5 MPa, rising to 1767 N at the 0.9 MPa peak operating pressure. The 20 mm hardened rod and 21 mm adjustable cushion suit this model to long-travel push, lift and eject motions where the piston must be slowed gently at each end. The cushion only decelerates the piston near stroke end - it does not lock or hold the load, so any position that must be held without live air pressure needs a mechanical lock, external rod brake, or pilot-operated check valve.

A 470 mm stroke clears a deep die cavity on a 200-ton press, and the 982 N push at 0.5 MPa (1767 N at 0.9 MPa) ejects formed brackets without deforming thin-gauge parts. NPT 1/4 ports connect directly to standard press-shop fittings.
The long 470 mm sweep pushes mixed-size cartons fully off a 600 mm-wide takeaway belt, while the built-in magnet and an EMSG switch confirm home and extended positions for the PLC diverter logic.
Lifting the sliding gate of a powder-coat cure oven needs travel, not brute force - 825 N pull at 0.5 MPa raises a light gate leaf, and the adjustable 21 mm cushion stops the door slam at both ends of travel.
Because the trailing T on this model specifies NPT 1/4 in tapered ports, match it to your existing North-American fittings, manifolds and hose standard - do not substitute the PT-threaded SC50X470-S unless your plumbing uses Rc taper threads. Size in both directions: if 982 N at 0.5 MPa is marginal for your load, step up to the SC63 (1559 N at 0.5 MPa); if you are overspending on air, the SC40 (628 N at 0.5 MPa) may be enough. At 470 mm of stroke the rod is long relative to its 20 mm diameter, so side load or off-axis tooling will bend the rod and wear the bearing. Manage this with an external linear guide carrying the load, or specify a guided cylinder version, and keep the thrust axis aligned with the load centre. When replacing an existing unit, match all five points: bore, stroke, port thread (NPT here, not PT/G), mounting accessory (LB, FA, FB, CA, CB, TC, TCM1), and magnet suffix (-S).
Quick checklist
At 0.5 MPa the 50 mm bore delivers 982 N on extension and 825 N on retraction (the rod side area is smaller). At the 0.9 MPa maximum operating pressure, push force rises to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf. Subtract your load's friction and side-load losses before sizing, and remember the cylinder cannot hold position without live air pressure.
Yes if there is any side load. With a 470 mm stroke on a 20 mm rod, even modest off-axis force bends the rod and wears the front bearing, so carry the load on an external linear guide or choose a guided cylinder version. For a like-for-like replacement, match bore (50 mm), stroke (470 mm), port thread (NPT 1/4 in - the T suffix), mounting accessory code and the magnet (-S). Confirm accessory part numbers from the datasheet.
