This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X20CB, 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 SU32X20CB
The AirTAC Airtac SU32~50 Standard Cylinder SU32X20CB is a double-acting profile-type standard cylinder with a Ø32mm bore and 20mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X20CB, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X20CB
The AirTAC SU32X20CB is a discontinued double-acting profile-type standard cylinder with a 32 mm bore and 20 mm stroke. It delivers 402 N push force at 0.5 MPa through a 1/8" port. AirTAC replaced this end-of-line unit with the SAU32X20CB, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series CB mounting interface.
Because this SKU lacks a magnet (-S), it cannot accept a sensor. The SAU successor also uses modern CMSG/DMSG/EMSG switches, whereas the legacy SU relied on CS1-B/DS1-B reed sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the original SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X20CB carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X20CB 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 SU32X20CB Is Used
Short-Stroke Clamping
Ideal for compact 20 mm clamping tasks in machining fixtures, delivering 402 N of push force at 0.5 MPa within a tight footprint.
Small Part Ejection
Provides reliable ejection of lightweight components from automated test benches or assembly lines using its 345 N pull force.
Gripping Transfer Stops
Acts as a compact stopper or diverter in material handling systems, utilizing the CB rear hinge mount for pivoting motion.
Replacing the Airtac SU32~50 Standard Cylinder SU32X20CB with the SAU32X20CB
To replace the SU32X20CB, order the SAU32X20CB. Verify your 1/8" port thread (PT, G, or NPT) and confirm the CB mounting accessory is retained. Since this 20 mm stroke SKU has no magnet (-S), it cannot support position sensing; if you need switches, specify an SAU32X20CB-S and migrate to CMSG/DMSG/EMSG sensors. The 32 mm bore yields 402 N push at 0.5 MPa; if undersized, step up to the 40 mm bore (628 N push). For load holding, note that a standard cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for suspended loads.
Replacement checklist
- ✓ Same bore / stroke → SAU32X20CB
- ✓ 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 SU32X20CB FAQ
Yes, the SU32X20CB is discontinued. The direct replacement is the AirTAC SAU32X20CB. It shares the same 32 mm bore, 20 mm stroke, 402 N force, 1/8" port, and SC-series CB mounting, fitting the same application directly.
At 0.5 MPa it provides 402 N push and 345 N pull; at 0.7 MPa it pushes 563 N, with a theoretical max of 82 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot accept sensors; the SAU replacement uses CMSG/DMSG/EMSG switches if sensing is required.
