This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X165, 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 SU100X165
The AirTAC Airtac SU63-100 Standard Cylinder SU100X165 is a double-acting profile-type standard cylinder with a Ø100mm bore and 165mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X165, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X165
The AirTAC SU100X165 is a discontinued double-acting profile-type cylinder with a 100mm bore and 165mm stroke. Delivering 3927 N push force at 0.5 MPa, its extruded aluminum barrel is more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this unit with the SAU100X165 direct replacement, retaining the exact 1/2" port, M20x1.5 rod thread, 29mm cushions, output force, and SC-series mounting.
Because this SKU lacks a magnet (-S), it cannot accept a sensor. If you previously used a magnet-equipped SU, note the SAU upgrade transitions from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors, and the SAUF variant adds a built-in valve the SU line never had.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X165 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SU63-100 Standard Cylinder SU100X165 Is Used
Heavy-Duty Pressing
Applies the 3927 N push force at 0.5 MPa to seat bearings or stake metal components securely in automated fabrication lines.
Bulk Material Diversion
Actuates heavy routing gates on high-capacity conveyors, relying on the 29mm adjustable air cushions to decelerate the 25mm rod smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU100X165 with the SAU100X165
To replace this SU100X165, order the SAU100X165 direct equivalent, verifying your 1/2" port, M20x1.5 rod thread, and SC-series mounting accessories. Since this specific SKU has no magnet, it cannot accept a sensor; if sensing is required, specify an SAU100X165-S and migrate to CMSG/DMSG/EMSG switches. For loads needing 5497 N at 0.7 MPa, this 100mm bore is ideal, whereas dropping to an 80mm bore yields 2513 N at 0.5 MPa. A plain cylinder drifts on air loss—the 29mm cushions only decelerate the piston—so install an external rod lock or pilot-operated check valve for load holding. For stroke lengths at or above 300mm, guide the load to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same bore / stroke → SAU100X165
- ✓ 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 SU100X165 FAQ
Yes, the SU100X165 is discontinued. The direct replacement is the AirTAC SAU100X165. It shares the identical 100mm bore, 165mm stroke, 1/2" port, output force, and SC-series mounting, so it bolts right in. The SAU line also adds the SAUF built-in-valve option the SU lacked.
At 0.5 MPa it pushes 3927 N and pulls 3681 N; at 0.7 MPa it pushes 5497 N, with a theoretical max of 801 kgf at 1.0 MPa. This specific SKU has no magnet and cannot take a sensor. If you need sensing, order the SAU100X165-S replacement, which uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
