This model is discontinued

AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X300SN, 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 SU63X300SN

The AirTAC SU63-100 Standard Cylinder SU63X300SN is a double-acting profile-type standard cylinder with a Ø63mm bore and 300mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X300SN, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X300SN

The AirTAC SU63X300SN is a discontinued double-acting profile-type cylinder with a 63mm bore and 300mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa via a 3/8" port. AirTAC replaced it with the SAU63X300SN, a direct replacement retaining the exact bore, stroke, force, port, and SC-series mounting.

This SU-SKU used legacy CS1-B/DS1-B sensors, whereas the SAU uses CMSG/DMSG/EMSG switches. The NBR seal handles -20 to +70C, and the SAU line adds a SAUF valve-integrated option.

Ejects formed metal parts from a press, requiring the 1402N pull force at 0.5MPa.

Replacing the Airtac SU63-100 Standard Cylinder SU63X300SN with the SAU63X300SN

To replace this cylinder, order the SAU63X300SN. Confirm the 3/8" port, M16x1.5 rod thread, and SC-series mounts. Because this has a -S magnet, you must upgrade to CMSG/DMSG/EMSG sensors. For a 300mm stroke, use external guides to prevent rod bending under side loads. A plain cylinder drifts on air loss; use a rod lock for holding. The 63mm bore yields 1559N push at 0.5MPa; step down to a 50mm bore (982N) or up to an 80mm bore (2513N) if needed.

Replacement checklist

  • ✓ Same bore / stroke → SAU63X300SN
  • ✓ 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 SU63X300SN FAQ

Yes, the SU63X300SN is discontinued. The direct replacement is the AirTAC SAU63X300SN. It shares the identical 63mm bore, 300mm stroke, 3/8" port, output force, and SC-series mounting accessories, so it fits the same application.

It delivers 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a max of 318kgf at 1.0MPa. The -S magnet on this legacy model works with CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
