The AirTAC Airtac SC Standard Cylinders SC40X500 is a genuine double-acting standard air cylinder with a Ø40mm bore and 500mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X500 is a double-acting tie-rod cylinder with a 40 mm bore and a long 500 mm stroke. At 0.5 MPa it delivers about 628 N on the push stroke and 528 N on the pull stroke, rising to 879 N at 0.7 MPa and 1130 N at the 0.9 MPa peak. The 16 mm rod carries that force over the full travel, and 21 mm adjustable cushions at both ends tame the piston as it decelerates into the caps.
With a 142 mm body length A, the extended length of this cylinder is roughly 642 mm, so check the envelope of your machine before ordering. It runs on 40 um filtered air at 0.15-1.0 MPa, from -20 to +70 C with the standard TPU seals, and ports are PT1/4. Speed range for this bore class is 30-800 mm/s.

A 500 mm stroke pushes or pulls product across a full conveyor lane, with 628 N at 0.5 MPa enough for cartons, totes and palletised layers.
The 16 mm rod and 879 N thrust at 0.7 MPa lift jigs, gates and small hoppers through 500 mm of vertical travel; add a guide for any off-centre load.
Drives machine slides, ejectors and clamp arms where 500 mm of travel and 21 mm end cushions give smooth, non-slamming stroke completion.
At 628 N push force, the SC40X500 sits between the SC32 (402 N at 0.5 MPa) and the SC50 (982 N). Step down to SC32 if your load is light and space is tight; step up to SC50 when the load climbs past roughly 500 kgf-equivalent or you want a stiffer 20 mm rod. A 500 mm stroke means a long, slender 16 mm rod: if there is any side load or the tooling is not guided, add an external guide rail or specify a guided cylinder, because long unsupported rods bend under side load and wear the front bearing.
Replacing an existing unit? Match all five points: 40 mm bore, 500 mm stroke, PT1/4 port thread (or G if the old cylinder used BSP parallel), the same mounting accessory, and the same magnet option. This SC40X500 is a basic-mount, non-magnetic cylinder with TPU seals, so it only swaps directly with another AirTAC SC tie-rod cylinder built to the same five points.
Quick checklist
At 0.5 MPa the SC40X500 pushes with about 628 N and pulls with about 528 N. At 0.7 MPa push force is roughly 879 N, and at the maximum operating pressure of 0.9 MPa it reaches about 1130 N. Theoretical maximum force at 1.0 MPa is around 128 kgf.
Not recommended. The 16 mm rod over a 500 mm stroke is relatively slender, so side loads cause rod bending and premature front-bearing wear. Mount an external guide or choose a guided cylinder arrangement, and match your replacement on bore, stroke, PT1/4 port thread, mounting accessory and magnet option.
