This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X65S, 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 SU80X65S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X65S is a double-acting profile-type standard cylinder with a Ø80mm bore and 65mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X65S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X65S
The AirTAC SU80X65S is a discontinued double-acting profile-type cylinder with an 80mm bore and 65mm stroke. It delivers 2513N push force at 0.5MPa via a 3/8 inch port. The direct replacement is the SAU80X65S, matching the bore, stroke, output, port and SC-series mounting.
The SAU upgrade uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S model, and adds a SAUF valve-integrated option. The cushion only decelerates; it does not hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X65S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X65S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 80 | Bore size in mm. |
| ×65 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU80X65S Is Used
Pallet Diversion
Pushes heavy pallets sideways at 65mm stroke using 2513N push force at 0.5MPa without requiring full system pressure.
Clamp Actuation
Secures large metal castings for machining, relying on the 80mm bore profile body and adjustable 28mm cushions for smooth stops.
Replacing the Airtac SU63-100 Standard Cylinder SU80X65S with the SAU80X65S
To replace this SU80X65S, order the SAU80X65S. Verify your 3/8 inch port, M20x1.5 rod thread and SC-series mounts. Because this SKU has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. A 65mm stroke is under the 300mm threshold, so rod bending is minimal. If stepping down to a 63mm bore yields 1559N push at 0.5MPa; stepping up to 100mm gives 3927N. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the cushion only decelerates. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU80X65S
- ✓ 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 SU80X65S FAQ
Yes, the SU80X65S is discontinued. The direct replacement is the SAU80X65S. It matches the 80mm bore, 65mm stroke, 2513N force, 3/8 inch port and SC-series mounting. You just order the SAU equivalent.
It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a max of 513kgf at 1.0MPa. The -S suffix means it has a magnet for legacy CS1-B/DS1-B switches. The SAU replacement upgrades these to CMSG/DMSG/EMSG sensors.
