This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X230SH, 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 SU50X230SH
The AirTAC SU32~50 Standard Cylinder SU50X230SH is a double-acting profile-type standard cylinder with a Ø50mm bore and 230mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X230SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X230SH
The AirTAC SU50X230SH is a discontinued double-acting profile cylinder with a 50mm bore, 230mm stroke, and a high-temperature Viton seal. It delivers 982 N of push force at 0.5 MPa. AirTAC replaced this unit with the SAU50X230SH, a direct replacement retaining the exact profile body, 1/4" port, M16x1.5 rod thread, and SC-series mounting compatibility.
This upgrade introduces current CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches used on this -S magnet model. The SAU line also adds 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 SAU50X230SH 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 SAU50X230SH produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×230 | 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 SU32~50 Standard Cylinder SU50X230SH Is Used
Hot Product Diversion
Routes packaged goods along heat-shrink tunnels using the 230mm stroke and Viton seals rated for 150C environments.
Clamping in Molding
Secures thermoplastic molds during heating cycles, utilizing 982 N of push force at 0.5 MPa with reliable high-temp endurance.
Replacing the Airtac SU32~50 Standard Cylinder SU50X230SH with the SAU50X230SH
To replace this SU50X230SH, order the SAU50X230SH, confirming the 50mm bore, 230mm stroke, 1/4" port, and high-temp Viton -H seal. Because the -S magnet is present, you must switch from the old CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family. If your application needs integrated flow control, explore the SAUF valve-integrated option. For sizing alternatives, a 40mm bore yields 628 N push at 0.5 MPa, while a 63mm bore provides 1559 N. A plain cylinder drifts on air loss, so add an external rod lock or pilot-operated check valve for load holding. At 230mm stroke, ensure guide alignment to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same bore / stroke → SAU50X230SH
- ✓ 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 SU50X230SH FAQ
Yes, the SU50X230SH is discontinued. The direct replacement is the SAU50X230SH. It matches the 50mm bore, 230mm stroke, 1/4" port, output force, and SC-series mounting, but uses current CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
The 50mm bore features a 1/4" port and M16x1.5 rod thread. It delivers 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. The Viton -H seal allows operation from 0 to 150 C.
