This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X30STC, 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 SU50X30STC
The AirTAC SU32~50 Standard Cylinder SU50X30STC 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 SAU50X30STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X30STC
The AirTAC SU50X30STC is a discontinued double-acting profile-type cylinder with a 50mm bore, 30mm stroke, and 1/4" port. It delivers 982N push force at 0.5MPa. AirTAC replaced this legacy unit with the SAU50X30STC, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting interface.
This compact extruded-aluminum body is shorter than an ISO 15552 cylinder of the same bore. Because your code includes -S, note the legacy CS1-B/DS1-B switches are obsolete; the SAU uses CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF valve-integrated option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X30STC 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 SAU50X30STC 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. |
| ×30 | 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 SU50X30STC Is Used
Short-Stroke Clamping
Ideal for securing 50kg workpieces in machining fixtures, utilizing the 982N push force within a compact 30mm travel envelope.
Package Diverting
Provides rapid sorting actuation on conveyor lines where the 30mm stroke pushes lightweight goods to alternate lanes without lag.
Pallet Stop Gates
Acts as a compact pneumatic stop for pallet accumulation, delivering reliable stopping force while saving space via the profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU50X30STC with the SAU50X30STC
To replace this SU50X30STC with the SAU50X30STC, verify the 50mm bore, 30mm stroke, and 1/4" port. Your TC mounting is an SC-series accessory that carries over directly. The -S magnet means you must upgrade sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG. For force sizing, this bore pushes 982N at 0.5MPa; if you need less force step down to a 40mm bore (628N), or step up to 63mm (1559N) for more. A plain cylinder drifts without live air—the cushion only decelerates—so fit an external rod lock for held loads. If you need self-switching, explore the SAUF variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X30STC
- ✓ 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 SU50X30STC FAQ
Yes, the SU50X30STC is discontinued. The direct replacement is the AirTAC SAU50X30STC, matching the 50mm bore, 30mm stroke, 1/4" port, force, and SC-series TC mounting.
It pushes 982N and pulls 825N at 0.5MPa, pushes 1374N at 0.7MPa, with a theoretical max of 200kgf at 1.0MPa. The -S magnet works with legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
