The AirTAC Airtac SC Standard Cylinders SC100X300T is a genuine double-acting standard air cylinder with a Ø100mm bore and 300mm stroke, PT1/2 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC100X300T is a double-acting tie-rod cylinder with a 100 mm bore and 300 mm stroke, configured with NPT 1/2 in tapered ports for North-American pipe plumbing. At 0.5 MPa it produces about 3927 N of push force, and at the 0.9 MPa upper end of its operating band it reaches 7068 N - enough to stamp, eject or press steel and aluminum parts without a booster. The 300 mm stroke sits well inside the 1500 mm maximum standard stroke for this bore, so it is a catalog item, not a made-to-order length. Under the rod end cover is a 29 mm adjustable cushion, the longest in the SC range up to this size, which decelerates the 25 mm rod piston near end of stroke and softens impact at these force levels. The body length A is 188 mm, giving an extended length of roughly 488 mm - noticeably shorter than an ISO 15552 cylinder of the same stroke, which is why the SC fits into tighter machine envelopes.

A 300 mm stroke lets the piston draw back clear of the fixture, and 7068 N at 0.9 MPa swages or flattens mild-steel brackets in a workholding press.
Rejects full-layer pallet loads sideways on a conveyor line; the NPT 1/2 ports tie directly into the plant's threaded pipe drops common in US distribution centers.
Extracts a deep core from a molded housing on a 300 mm pull; the 29 mm adjustable cushion stops the core gently so the mold parting line is not hammered stroke after stroke.
Thread is the first checkpoint: the SC100X300T ends in T, meaning NPT 1/2 tapered ports that seal on the thread itself with sealant or tape. If your machine is a North-American build with NPT manifold blocks and pipe nipples, this is the correct variant; European or Asian OEM lines usually run the G (BSPP parallel) version instead, which seals on a bonded face washer. Match the thread to your existing fittings before ordering - adapters work, but a straight thread match is cleaner and leak-proof. Size both ways before committing: the next bore down, SC80, delivers 2513 N push at 0.5 MPa, while the next bore up, SC125, delivers 6136 N. If your load plus friction sits well below 3000 N, the 80 mm bore saves air and space; above about 4500 N, step to the 125. At 300 mm of stroke the slender 25 mm rod will bend under side load, so guide the tooling externally or specify a guided cylinder rather than letting the rod carry lateral force. For replacement, match bore, stroke, port thread, mounting accessory and magnet (-S) exactly.
Quick checklist
At 0.5 MPa: 3927 N push and 3681 N pull. At 0.7 MPa: 5497 N push. At the 0.9 MPa maximum operating pressure: 7068 N push. The theoretical maximum at 1.0 MPa is 801 kgf. Subtract seal friction and the load of your tooling from these figures when sizing; the pull side is always lower because the 25 mm rod reduces the effective annulus area.
Only for another AirTAC SC tie-rod cylinder - or a functionally identical tie-rod design - with the same 100 mm bore, 300 mm stroke, NPT 1/2 port thread, mounting accessory and magnet option. It is shorter than an ISO 15552 profile cylinder of the same stroke, so it is not dimensionally interchangeable with ISO 15552 hardware. Confirm port thread before swapping: the T version has NPT tapered ports, not the standard PT (Rc) or G (BSPP) threads.
