This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X30S, 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 SU50X30S
The AirTAC Airtac SU32~50 Standard Cylinder SU50X30S is a double-acting profile-type standard cylinder with a Ø50mm bore and 30mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X30S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X30S
The AirTAC SU50X30S is a discontinued double-acting profile-type cylinder with a 50mm bore and 30mm stroke. Built with an extruded aluminum barrel and adjustable air cushions at both ends, it delivers 982 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAU50X30S, a direct upgrade retaining the exact bore, stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting compatibility.
When upgrading to the SAU50X30S, your body dimensions and output force remain identical, but the sensor family changes: the SU's -S magnet used legacy CS1-B/DS1-B switches, whereas the SAU requires current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X30S 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 SAU50X30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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 SU50X30S Is Used
Short-Stroke Clamping
Ideal for holding parts during machining, utilizing the 30mm stroke and 982 N push force to secure workpieces firmly without excessive travel.
Package Diverting
Provides rapid actuation for sorting or diverting light packages on a line, where the compact profile body saves valuable machine space.
Pallet Stopper Gate
Functions as a reliable pneumatic stop for pallets, using the 50 kg vertical lift capacity to control product flow safely.
Replacing the Airtac SU32~50 Standard Cylinder SU50X30S with the SAU50X30S
To replace the SU50X30S, order the SAU50X30S, confirming the 1/4" port, M16x1.5 rod thread, PT/G/NPT thread standard, and your SC-series mounting brackets (LB/FA/FB/CA/CB). Because this SKU includes the -S magnet, you must upgrade your switches from the old CS1-B/DS1-B to the modern CMSG/DMSG/EMSG family. If your application needs integrated flow control, consider the SAUF variant with its built-in 4M valve. For sizing alternatives, a 40mm bore provides 628 N push at 0.5 MPa, while a 63mm bore yields 1559 N. Note that a plain cylinder drifts without live air—the cushion only decelerates near stroke end—so add an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU50X30S
- ✓ 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 SU50X30S FAQ
Yes, the AirTAC SU50X30S is discontinued. The direct replacement is the SAU50X30S. It matches the original 50mm bore, 30mm stroke, 1/4" port, output force, and SC-series mounting accessories, fitting the exact same application.
At 0.5 MPa, it provides 982 N push and 825 N pull force; 1374 N push at 0.7 MPa; and a theoretical max of 200 kgf at 1.0 MPa. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades these to CMSG/DMSG/EMSG sensors.
