This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X75S, 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 SU80X75S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X75S is a double-acting profile-type standard cylinder with a Ø80mm bore and 75mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X75S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X75S
The AirTAC SU80X75S is a discontinued double-acting profile cylinder with an 80 mm bore and 75 mm stroke. AirTAC replaced this unit with the SAU80X75S, a direct replacement retaining the exact bore, stroke, output force, 3/8" port, and SC-series mounting.
The extruded aluminum profile is shorter than an 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 requires current CMSG/DMSG/EMSG sensors. The SAU family also adds a 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 SAU80X75S 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 SAU80X75S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU80X75S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×75 | 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 SU80X75S Is Used
Heavy Press Ejection
Provides the 2513 N push force at 0.5 MPa needed to reliably eject dense metal stampings from a hydraulic press bed.
Pallet Diverting
Handles robust 75 mm strokes to push heavy loaded pallets onto secondary packaging lines without requiring external guides.
Replacing the Airtac SU63-100 Standard Cylinder SU80X75S with the SAU80X75S
To replace this discontinued SU80X75S, order the SAU80X75S. Verify your 80 mm bore, 75 mm stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) match. Since this is an -S magnet model, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If sizing alternatives, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. A plain cylinder drifts without live air; the 28 mm adjustable cushion only decelerates the piston. For load holding on air loss, install an external rod lock or pilot-operated check valve. If you need integrated pneumatic control, explore the SAUF built-in-valve variant.
Replacement checklist
- ✓ Same bore / stroke → SAU80X75S
- ✓ 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 SU80X75S FAQ
Yes, the SU80X75S is discontinued. The direct replacement is the AirTAC SAU80X75S. It shares the identical 80 mm bore, 75 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 it pushes 3518 N, with a theoretical max of 513 kgf at 1.0 MPa. Because this is an -S magnet model, it used legacy CS1-B/DS1-B switches; upgrading to the SAU requires switching to current CMSG/DMSG/EMSG sensors.
