The AirTAC Airtac SE ISO 15552 Cylinders SE50X165G is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø50mm bore and 165mm stroke, PT1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SE50X165G is a double-acting, single-rod profile cylinder built to the ISO 15552 / VDMA 24562 interface, fitted with G1/4 BSPP ports - the parallel-thread option of the SE50 series. At 0.5 MPa it delivers 982 N on extend and 825 N on retract, climbing to 1374 N at 0.7 MPa, a force class well matched to carton pushing, fixture clamping and gate actuation. The 165 mm stroke is inside the 50 mm bore's 1200 mm standard range, so this is supplied as a catalogue build. What separates the G variant from the default PT model is the port itself: the G1/4 thread is cut parallel and seals on a bonded face washer or O-ring at the fitting, not on the thread flanks - the standard plumbing style on many EU and Asia OEM manifolds, usually a made-to-order thread versus the tapered PT version. The square extruded aluminum barrel carries no external tie rods, so the body mounts flush against machine plates and resists corrosion in open framing. Adjustable cushion screws at both ends (30 mm cushion travel on this bore) let you tune deceleration at the end stops from the field, and the 20 mm hard-chrome rod with M16x1.5 thread handles the side loads typical of pusher tooling.

Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B). Seals: TPU (blank) / FKM high-temp (H) / NBR (N). Thread: PT (blank) / G. Mounting: Basic, LB, FA, FB, CA, CB, CR, TC, FTC, TCM1, TCM2. Related SE-family variants: SED (double rod), SEJ (adjustable stroke), BSE (rod lock), BSED (double-rod rod lock).
Ejects corrugated cases from an infeed conveyor lane into a shrink-wrap magazine across a 165 mm transfer. The 982 N extend force at 0.5 MPa comfortably moves stacked cartons, while field-adjustable cushions keep the push from slamming the case stop.
Actuates a diverter gate that routes PET bottles between filler lanes. A G1/4 BSPP port bolts straight onto the stainless manifold common on European bottling OEMs, and 825 N retract pulls the gate back against line back-pressure.
Clamps aluminium brackets into a drilling jig for a 165 mm-stroke load/unload cycle. The 1374 N push at 0.7 MPa holds the workpiece against drill torque, and the 20 mm hard-chrome rod resists the coolant mist around the machine.
Size in both directions before ordering: if 982 N of extend force at 0.5 MPa overshoots the load, the SE40 next bore down provides 628 N at the same pressure; if the tooling sees shock or heavier inertia, the SE63 steps up to 1559 N. For a retrofit, match the outgoing ISO 15552 cylinder on bore (50 mm), stroke (165 mm), mounting style (Basic, LB, FA, FB, CA, CB, TC or trunnion variants) and add the -S magnet only if CMSE / DMSE switches will sense position. On plumbing, confirm your regional standard first: this model takes BSPP parallel fittings sealing on a bonded washer - if your manifold is tapped for tapered PT/Rc threads, order the SE50X165 rather than the G version so the ports match your existing hardware.
Quick checklist
At 0.5 MPa the 50 mm bore produces 982 N push (extend) and 825 N pull (retract); at 0.7 MPa push rises to 1374 N. At the full 1.0 MPa rating the maximum push is 200 kgf. Extension always exceeds retraction because air acts on the full bore area when extending and only the annulus around the 20 mm rod when retracting.
Yes - the SE follows the ISO 15552 / VDMA 24562 mounting interface, so it is dimensionally interchangeable with other ISO 15552 cylinders of matching bore and stroke; match the mounting accessory and add -S if CMSE (reed) or DMSE (electronic) switches are needed. The G suffix means the 1/4 in ports are G (BSPP) parallel threads that seal on a bonded washer at the fitting, unlike the tapered default PT/Rc version - verify which standard your fittings and manifold use before ordering, since the two threads do not interchange reliably.
