This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X30S, 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 SU80X30S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X30S is a double-acting profile-type standard cylinder with a Ø80mm bore and 30mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X30S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X30S
The AirTAC SU80X30S is a discontinued double-acting profile-type cylinder with a 30 mm stroke. It delivers 2513 N of push force at 0.5 MPa through an extruded aluminum barrel, making it shorter and more compact than an ISO 15552 cylinder of the same bore. The direct replacement is the SAU80X30S, matching the 80 mm bore, 3/8" port, output force, and SC-series mounting.
The -S magnet on this legacy unit worked with CS1-B/DS1-B switches, but the SAU replacement uses current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF variant with a built-in valve the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X30S 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 SAU80X30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU80X30S Is Used
Short-Stroke Clamping
Ideal for high-force 2513 N clamping of heavy castings in CNC machining centers where a 30 mm stroke securely locks the part.
Heavy Diverting
Provides robust 80 mm bore actuation to push heavy pallets or bulk containers off a main conveyor line in packaging facilities.
Pallet Stopping
Acts as a heavy-duty end-stop for loaded pallets arriving at 30 mm height differentials, decelerating loads with its 28 mm cushion.
Replacing the Airtac SU63-100 Standard Cylinder SU80X30S with the SAU80X30S
To replace this discontinued SU80X30S, order the SAU80X30S. Verify your 3/8" port, M20x1.5 rod thread, PT/G/NPT thread standard, and SC-series mounting (LB/FA/FB/CA/CB) all carry over directly. Because this SKU includes a -S magnet, note the sensor family changes from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG on the SAU. If you need to downsize, a 63 mm bore gives 1559 N push at 0.5 MPa; if you need more force, a 100 mm bore yields 3927 N. A plain cylinder does not hold load without live air, so add an external rod lock or pilot-operated check valve for safety. For higher cycling automation, consider the SAUF built-in 4M solenoid valve option.
Replacement checklist
- ✓ Same bore / stroke → SAU80X30S
- ✓ 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 SU80X30S FAQ
Yes, the SU80X30S is discontinued. The direct replacement is the SAU80X30S. It shares the same 80 mm bore, 30 mm stroke, 3/8" port, output force, and SC-series mounting accessories, 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, and the theoretical max is 513 kgf at 1.0 MPa. The -S magnet on this unit works with legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
