This model is discontinued

AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X250, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.

Airtac SU63-100 Standard Cylinder SU80X250

The AirTAC Airtac SU63-100 Standard Cylinder SU80X250 is a double-acting profile-type standard cylinder with a Ø80mm bore and 250mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X250, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X250

The AirTAC SU80X250 is a discontinued double-acting profile-type cylinder with an 80mm bore and 250mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, using a 25mm rod and 3/8" port. AirTAC replaced this unit with the SAU80X250, a direct alternative retaining the exact body dimensions, force, and SC-series mounting.

The SAU upgrade introduces CMSG/DMSG/EMSG sensors (replacing the legacy CS1-B/DS1-B) and adds the SAUF built-in-valve option the SU lacked. Since this specific SKU has no magnet, it cannot accept a sensor.

Pushes heavy pallets off a main conveyor line, safely handling a 1508N working load while reusing existing AirTAC SC-series mounting brackets.

Replacing the Airtac SU63-100 Standard Cylinder SU80X250 with the SAU80X250

To replace this discontinued SU80X250, order the SAU80X250 direct equivalent, matching the 80mm bore, 250mm stroke, 3/8" port, and M20x1.5 rod thread. Because this SKU lacks a magnet (-S), it cannot support sensing; if you need position detection, specify an SAU80X250S and migrate to CMSG/DMSG/EMSG switches. For loads needing 3518N at 0.7MPa, step up to a 100mm bore; if 1767N suffices, step down to a 50mm bore. A plain cylinder drifts on air loss—the 28mm cushions only decelerate—so use an external rod lock or pilot-operated check valve for holding. At 250mm stroke, ensure guide alignment to prevent rod bending. The SAUF variant integrates a 4M valve if compact actuation is needed.

Replacement checklist

  • ✓ Same bore / stroke → SAU80X250
  • ✓ Port/thread type (PT/G/NPT)
  • ✓ Magnet (-S): sensor family CS1-B → CMSG
  • ✓ Mounting reused (FA/FB/CA/CB/LB)
  • ✓ Need a built-in valve? → SAUF

Airtac SU63-100 Standard Cylinder SU80X250 FAQ

Yes, the AirTAC SU80X250 is discontinued. The direct replacement is the SAU80X250. It shares the same 80mm bore, 250mm stroke, 3/8" port, output force, and SC-series mounting, so it fits the same application without mechanical modifications.

It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf maximum at 1.0MPa. This specific no-magnet SKU cannot accept sensors; the SAU replacement uses CMSG/DMSG/EMSG switches, but you must order the -S version for detection.
