This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X575S, 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 SU80X575S
The AirTAC SU63-100 Standard Cylinder SU80X575S is a double-acting profile-type standard cylinder with a Ø80mm bore and 575mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X575S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X575S
The AirTAC SU80X575S is a discontinued double-acting profile-type cylinder featuring an 80mm bore, 575mm stroke, and a 3/8" port. Delivering 2513 N of push force at 0.5 MPa, its extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore while sharing AirTAC SC-series mounting. The direct replacement is the SAU80X575S, matching the bore, stroke, output force, port size, and accessories.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace this unit's legacy CS1-B/DS1-B switches, and adds the SAUF built-in-valve option the SU line lacked. Note that standard cylinders drift without live air; the 28 mm cushions only decelerate, so use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X575S 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 SAU80X575S 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 SU80X575S Is Used
Pallet Diversion
Pushes heavy pallets across transfer lines using the 2513 N push force at 0.5 MPa, with external guides handling the 575 mm stroke.
Press Ejection
Ejects formed metal parts from hydraulic presses, benefiting from the compact profile body and 4523 N thrust available at 0.9 MPa.
Replacing the Airtac SU63-100 Standard Cylinder SU80X575S with the SAU80X575S
To replace this discontinued SU80X575S, order the SAU80X575S direct equivalent, verifying your 3/8" port, M20x1.5 rod thread, and SC-series mount. Because this is a 575 mm stroke, support the load with external guides to prevent rod bending and side-load wear. If downsizing, a 63 mm bore yields 1559 N push at 0.5 MPa; if upsizing, a 100 mm bore provides 3927 N. The -S magnet means your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. Remember, the cushion decelerates but does not hold; for load holding on air loss, install a pilot-operated check valve or rod lock. The SAUF variant offers a built-in valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU80X575S
- ✓ 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 SU80X575S FAQ
Yes, the SU80X575S is discontinued. The direct replacement is the SAU80X575S. It matches the 80 mm bore, 575 mm stroke, 3/8" port, 513 kgf max force, and SC-series mounting. You must upgrade your legacy CS1-B/DS1-B sensors to the CMSG/DMSG/EMSG family.
It has a 3/8" port. The force ratings are: 2513 N push and 2268 N pull at 0.5 MPa; 3518 N push at 0.7 MPa; 4523 N push at 0.9 MPa; and a theoretical maximum of 513 kgf at 1.0 MPa. The cylinder operates at 30-800 mm/s.
