The AirTAC Airtac SC Standard Cylinders SC32X140SHT is a genuine double-acting standard air cylinder with a Ø32mm bore and 140mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X140SHT is a double-acting tie-rod cylinder with NPT 1/8 in tapered ports and a built-in magnet, so CMSG, DMSG or EMSG switches can be mounted directly on the tube. At 0.5 MPa it pushes with about 402 N over its 140 mm stroke, rising to 724 N when run at the 0.9 MPa maximum operating pressure. This 32 mm bore carries a 12 mm rod with an M10x1.25 knuckle thread, a 21 mm adjustable cushion, and a 140 mm body length A, giving an extended length of roughly 280 mm. It runs on air filtered to 40 um at 0.15-1.0 MPa, with a speed range of 30-800 mm/s.

Swinging a divert gate on a parcel-conveyor line in a North-American distribution centre: the cylinder screws straight into NPT solenoid manifolds, and 402 N at 0.5 MPa moves lightweight gates across the 140 mm throw at up to 800 mm/s.
A small bench punch shearing tabs from rubber gaskets or soft shim stock: 563 N at 0.7 MPa shears thin non-metallic material, and the 21 mm adjustable cushion softens the break-through so the punch does not hammer the die.
Clamping small sheet-metal brackets in a weld jig: the built-in magnet lets a CMSG switch confirm the clamp is closed without adding external proximity sensors, a tidy option for compact NPT-plumbed fixtures.
Bore 32 is the smallest in the SC range, so the only sizing step is upward: if 402 N at 0.5 MPa is marginal for your load, move to the SC40, which gives 628 N at the same pressure. Keep the SHT version only when the machine is plumbed with NPT fittings and NPT manifolds, which is the norm on North-American builds; if your lines use PT (Rc) or G (BSPP) hardware, order the plain SC32X140S instead, because NPT (60 degree thread form) and PT (55 degree) do not seal interchangeably even though both taper. As a replacement, match five points before ordering: bore, stroke, port thread (NPT 1/8 on this SKU), the mounting accessory code, and the magnet suffix.
Quick checklist
At 0.5 MPa it pushes 402 N and pulls 345 N. At the common 0.7 MPa working pressure, push force is 563 N, and at the 0.9 MPa maximum operating pressure it reaches 724 N. The theoretical ceiling is about 82 kgf at 1.0 MPa. Deduct seal friction and derate for your mounting orientation when sizing the load.
Mechanically yes, if bore, stroke, mounting accessory and magnet all match, but the ports are the difference: this SHT version has NPT 1/8 tapered threads that seal on the thread with sealant, while the standard version uses PT (Rc) with a 55 degree form. Match the thread to your existing fittings and manifold. Note also that the SC is a tie-rod cylinder built shorter than an ISO 15552 body, so it is not an ISO 15552 drop-in replacement.
