This model is discontinued

AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X300-40, 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 SUJ Adjustable Cylinder SUJ32X300-40

The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X300-40 is a double-acting profile-type standard cylinder with a Ø32mm bore and 300mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X300-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X300-40

The AirTAC SUJ32X300-40 is a double-acting, double-rod profile cylinder with an adjustable stroke, discontinued and replaced by the direct replacement SAUJ32X300-40. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 260-300 mm stroke (the 300 mm nominal is the maximum). The stop sets the end position and is not a load lock. This 32 mm bore uses a 1/8" port, a Ø12 mm rod, and 21 mm adjustable cushions.

The SAUJ successor retains the exact bore, force, and FA/LB mounting, but upgrades sensing to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B. This non-magnet SKU cannot take a switch.

Where the Airtac SUJ Adjustable Cylinder SUJ32X300-40 Is Used

precision_manufacturing

Variable Pitch Indexing

Dialing the extend stop down 40 mm lets a 32 mm bore unit push parts to varying pitches on the same line without swapping cylinders.

conveyor_belt

Adjustable Transfer Stops

Trimming the extend stroke on-site sets precise 260-300 mm gate positions for diverting different carton widths off a belt.

Tunable Forming Depth

The external stop screw provides repeatable end-position tuning for a packaging press when material thickness varies run to run.

Replacing the Airtac SUJ Adjustable Cylinder SUJ32X300-40 with the SAUJ32X300-40

To replace the discontinued SUJ32X300-40, order the SAUJ32X300-40; it is a direct keeping the 32 mm bore, 300 mm max stroke, 40 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 40 mm adjust window if your extend target sits between 260 mm and 300 mm. Because this SKU lacks a magnet, it cannot accept a switch; the SAUJ requires CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. At a 300 mm stroke, use external guides to prevent rod bending and manage side loads. A plain cylinder drifts on air loss, so fit an external rod lock for held loads.

Replacement checklist

  • ✓ Same bore / stroke → SAUJ32X300-40
  • ✓ 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 SUJ Adjustable Cylinder SUJ32X300-40 FAQ

Yes, the SUJ32X300-40 is discontinued. The direct replacement is the SAUJ32X300-40. It shares the same 32 mm bore, 300 mm max stroke, 40 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors from the old CS1-B/DS1-B.

It is a double-acting double-rod cylinder with a 1/8" port. The nominal 300 mm stroke is the maximum; the external stop screw trims the extend stroke by up to 40 mm on-site, giving a 260-300 mm usable range. The stop sets end position and is not a load lock.
