This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X430S, 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 SU32~50 Standard Cylinder SU50X430S
The AirTAC SU32~50 Standard Cylinder SU50X430S is a double-acting profile-type standard cylinder with a Ø50mm bore and 430mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X430S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X430S
The AirTAC SU50X430S is a discontinued double-acting profile-type cylinder with a 50mm bore and 430mm stroke. AirTAC replaced this unit with the SAU50X430S, a direct upgrade retaining the exact 1/4" port, M16x1.5 rod thread, and SC-series mounting.
The SAU replacement matches the original body, force, and adjustable 21mm cushions, but upgrades the magnet sensing from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered. Because the 430mm stroke invites rod bending, use external guides to prevent side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X430S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X430S 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 SU32~50 Standard Cylinder SU50X430S Is Used
Mid-Range Sorting Diverter
Pushes 50 kg cartons laterally on a packaging line using the 430mm stroke, operating safely within the 589 N working load limit.
Vertical Lift Gate
Raises a lightweight access panel, benefiting from the compact profile body while requiring an external check valve to hold the load.
Long-Reach Part Ejector
Clears machined components from a press bed, relying on external guides to prevent rod bending over the 430mm extension.
Replacing the Airtac SU32~50 Standard Cylinder SU50X430S with the SAU50X430S
To replace the SU50X430S, order the SAU50X430S direct equivalent, verifying your 1/4" port thread (PT, G, or NPT) and SC-series mounting hardware. If downsizing, a 40mm bore provides 628 N push at 0.5 MPa; if upsizing, an 63mm bore yields 1559 N. The -S magnet on your legacy cylinder supported CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors. For the 430mm stroke, add external guides to prevent rod bending. Remember that a plain cylinder drifts without live air; use an external rod lock or pilot-operated check valve for load holding. Consider the SAUF variant if you need a built-in 4M valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X430S
- ✓ 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 SU32~50 Standard Cylinder SU50X430S FAQ
Yes, the AirTAC SU50X430S is discontinued. The direct replacement is the SAU50X430S. It shares the identical 50mm bore, 430mm stroke, 1/4" port, output force, and SC-series mounting, so it drops right into the same application.
The cylinder provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical maximum of 200 kgf at 1.0 MPa. Because your SU model has an -S magnet for legacy CS1-B/DS1-B switches, note that the SAU replacement requires the newer CMSG/DMSG/EMSG sensor family.
