This model is discontinued

AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X900S, 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 SU100X900S

The AirTAC SU63-100 Standard Cylinder SU100X900S is a double-acting profile-type standard cylinder with a Ø100mm bore and 900mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X900S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X900S

The AirTAC SU100X900S is a discontinued double-acting profile-type cylinder with a 100mm bore and 900mm stroke. Delivering 3927N push force at 0.5MPa, it features an extruded aluminum barrel and 1/2" ports. AirTAC replaced it with the SAU100X900S, a direct replacement matching the bore, stroke, force, and SC-series mounting.

This long-stroke unit carries a piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU family also adds a SAUF valve-integrated option. Note that a plain cylinder drifts without live air; use an external rod lock for holding.

Where the Airtac SU63-100 Standard Cylinder SU100X900S Is Used

conveyor_belt

Heavy Material Transfer

Drives large pallets or heavy assemblies over 900mm on conveyor lines, utilizing the 3927N push force at 0.5MPa to move substantial loads reliably.

warehouse

Automated Warehousing

Executes long-stroke pushing and sorting of heavy inventory at distribution hubs, where the compact profile saves space compared to standard ISO cylinders.

precision_manufacturing

Large Press Feeding

Feeds heavy sheet metal or components into industrial presses, requiring external guides to support the 900mm stroke and prevent rod bending under high side loads.

Replacing the Airtac SU63-100 Standard Cylinder SU100X900S with the SAU100X900S

To replace this SU100X900S, order the SAU100X900S. Verify your 1/2" port, M20x1.5 rod thread, and SC-series mounting. Because this has an -S magnet, plan to swap legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors. If you need self-switching, explore the SAUF valve-integrated variant. For forces, the 100mm bore yields 3927N push at 0.5MPa; if undersizing, an 80mm bore gives 2513N. At 900mm, prevent rod bending by using external guides to manage side loads. The cushion only decelerates; install a pilot-operated check valve to hold loads.

Replacement checklist

  • ✓ Same bore / stroke → SAU100X900S
  • ✓ 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 SU100X900S FAQ

Yes, the SU100X900S is discontinued. The direct replacement is the SAU100X900S. It matches the 100mm bore, 900mm stroke, 3927N force, 1/2" port, and SC-series mounting. You can swap it directly without modifying your machine.

At 0.5MPa it pushes 3927N and pulls 3681N; at 0.7MPa it pushes 5497N, with a theoretical max of 801kgf at 1.0MPa. This -S model uses legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
