This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X165S, 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 SU80X165S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X165S is a double-acting profile-type standard cylinder with a Ø80mm bore and 165mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X165S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X165S
The AirTAC SU80X165S is a discontinued double-acting profile cylinder with an 80 mm bore and 165 mm stroke. It delivers 2513 N push force at 0.5 MPa. The direct replacement is the SAU80X165S, matching the exact bore, stroke, 3/8" port, and SC-series mounting.
The SAU upgrade switches the -S magnet to CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B, and adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X165S 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 SAU80X165S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×165 | 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 SU80X165S Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line utilizing the 2513 N push force at 0.5 MPa.
Carton Stacking
Actuates a 165 mm stroke lifting flap to align large corrugated cartons before strapping.
Clamp Actuation
Secures heavy steel weldments during machining, relying on the 128 kg vertical lift capacity.
Replacing the Airtac SU63-100 Standard Cylinder SU80X165S with the SAU80X165S
To replace this SU80X165S, order the SAU80X165S. Verify the 3/8" port, M20x1.5 rod thread, and SC-series mounting. Because the -S magnet is present, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If sizing neighbors, a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. The cushion only decelerates; for load holding on air loss, use an external rod lock or pilot-operated check valve. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU80X165S
- ✓ 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 SU80X165S FAQ
Yes, the SU80X165S is discontinued. The direct replacement is the SAU80X165S. It shares the same 80 mm bore, 165 mm stroke, output force, 3/8" port, and SC-series mounting, so it fits the same application directly.
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa push is 3518 N, with a theoretical max of 513 kgf at 1.0 MPa. The -S magnet works with legacy CS1-B/DS1-B switches; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
