The AirTAC Airtac SC Standard Cylinders SC80X175ST is a genuine double-acting standard air cylinder with a Ø80mm bore and 175mm stroke, PT3/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC80X175ST is a double-acting tie-rod cylinder with NPT 3/8 in tapered ports, sized for North-American pipe plumbing where fittings seal on the thread itself rather than on a face washer. Its 80 mm bore delivers about 2513 N of push force at 0.5 MPa and up to 4523 N at the 0.9 MPa maximum, putting this model in the medium-heavy thrust class between the 63 mm and 100 mm bores. The 175 mm stroke (a standard size, no made-to-order surcharge) suits mid-length transfers, gate actuation and clamping slides. The piston carries a built-in magnet as standard on this suffix, so CMSG/DMSG/EMSG reed or hall sensors can report end positions without external brackets. Inside, a 25 mm chrome rod runs in the front head, and the adjustable cushion works over a 28 mm deceleration stroke at each end to soften piston landing at cycle speeds up to 800 mm/s. The tie-rod body measures 182 mm (dimension A) before stroke, so the fully extended length is roughly 357 mm.

With 2513 N at 0.5 MPa the SC80X175ST shoves a loaded 600 mm pallet section sideways off a conveyor in one 175 mm move, while the built-in magnet confirms the retracted park position to the PLC every cycle.
The 80 mm bore holds a hinged chute gate against fabric spring-back, and the 28 mm adjustable cushion keeps the 25 mm rod from hammering the gate stop at the 30-800 mm/s speed range's upper end.
At 0.7 MPa this cylinder delivers 3518 N - enough to strip finished castings off the trim die, with NPT 3/8 ports tying straight into the press's existing imperial solenoid-valve manifold.
Size both ways before committing: stepping down to an SC63 of the same stroke gives you 1559 N at 0.5 MPa - enough only if your load plus friction stays under roughly 140 kgf with a safety margin. Stepping up to an SC100X175 raises thrust to 3927 N at 0.5 MPa if you need headroom or plan to run below 0.5 MPa. At 175 mm stroke the 25 mm rod is comfortably inside its buckling limit for pure axial load, but any side load or long overhang calls for an external guide rail or an F-SC80-guided arrangement. Plumbing note: the ST suffix means NPT tapered ports - match it to existing NPT fittings and manifolds; if your line is plumbed to European BSPP standards with bonded-washer sealing, order the G-suffix version instead. For a like-for-like replacement, match all five points: 80 mm bore, 175 mm stroke, NPT3/8 port thread, mounting accessory (F-SC80LB, FA, FB, CA, CB, TC or TCM1) and the magnet suffix - this unit already includes -S.
Quick checklist
At 0.5 MPa it pushes with 2513 N and pulls with 2268 N (the difference is the 25 mm rod area). At the 0.9 MPa maximum operating pressure, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf. Real usable force is lower by seal friction and supply-line drop, so size with a 25-50% margin.
T designates NPT 3/8 in tapered pipe ports instead of the standard PT (Rc) threading - both are tapered and seal on the thread, and the two are mechanically similar enough that a thread-conversion fitting usually bridges them. Beyond the port thread, a drop-in replacement must match the same 80 mm bore, 175 mm stroke, mounting accessory and magnet (-S). The SC is a tie-rod cylinder, not an ISO 15552 profile - it is shorter than ISO 15552 dimensions, so it is not dimensionally interchangeable with ISO 15552 cylinders.
