This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X375S, 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 SU80X375S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X375S is a double-acting profile-type standard cylinder with a Ø80mm bore and 375mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X375S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X375S
The AirTAC SU80X375S is a discontinued double-acting profile-type cylinder with an 80 mm bore and 375 mm stroke. It delivers 2513 N push force at 0.5 MPa through a 3/8 inch port. AirTAC replaced this EOL unit with the SAU80X375S, a direct alternative retaining the exact bore, stroke, force, port size, and SC-series mounting footprint.
The compact extruded aluminum body is shorter than a standard ISO 15552 cylinder of the same bore. Because this SKU includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches; the SAU replacement upgrades to current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X375S 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 SAU80X375S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×375 | 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 SU80X375S Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line using the 2513 N thrust at 0.5 MPa, with the 375 mm stroke clearing the belt frame completely.
Press Ejection
Ejects dense stamped parts from a press bed, where the compact profile body saves machine space compared to older ISO standard cylinders.
Replacing the Airtac SU63-100 Standard Cylinder SU80X375S with the SAU80X375S
To replace this discontinued SU80X375S, order the SAU80X375S. Verify your 3/8 inch port threads (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, TC). Because this is an -S magnet model, note that your legacy CS1-B/DS1-B switches are obsolete and must be replaced by CMSG, DMSG, or EMSG sensors on the SAU. If you need self-switching control, consider the SAUF80 variant with its integrated 4M valve. For load holding, a plain cylinder drifts on air loss—the 28 mm cushions only decelerate—so add an external rod lock or pilot-operated check valve. With a 375 mm stroke, use external guides to prevent rod bending under side loads. If downsizing, a 63 mm bore yields 1559 N push at 0.5 MPa; if upsizing, a 100 mm bore provides 3927 N.
Replacement checklist
- ✓ Same bore / stroke → SAU80X375S
- ✓ 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 SU80X375S FAQ
Yes, the SU80X375S is discontinued. The direct replacement is the AirTAC SAU80X375S. It matches the 80 mm bore, 375 mm stroke, 3/8 inch port, output force, and SC-series mounting. You simply order the SAU80X375S as a direct fit.
The force ratings are 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a maximum theoretical force of 513 kgf at 1.0 MPa. Because your SU model has a magnet (-S), the old CS1-B/DS1-B switches are obsolete; the SAU replacement requires current CMSG, DMSG, or EMSG sensors.
