This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X650, 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 SU32X650
The AirTAC Airtac SU32~50 Standard Cylinder SU32X650 is a double-acting profile-type standard cylinder with a Ø32mm bore and 650mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X650, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X650
The AirTAC SU32X650 is a discontinued double-acting profile-type cylinder with a 32mm bore and 650mm stroke. It delivers 402N push force at 0.5MPa via a 1/8 port. AirTAC replaced it with the SAU32X650, a direct upgrade retaining the exact bore, stroke, output, and SC-series mounting.
The SAU upgrade uses current CMSG/DMSG/EMSG sensors, whereas this legacy SU used CS1-B/DS1-B switches. Since this specific SKU lacks a magnet, it cannot accept any sensor. The SAU also introduces the SAUF valve-integrated variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X650 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 SAU32X650 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 SU32X650 Is Used
Bin Actuation
Extends 650mm to open tall storage chute doors where a compact 32mm profile body is required.
Light Part Ejection
Cycles at 30-800 mm/s to eject small plastic moldings from a press, needing external guides for the long rod.
Replacing the Airtac SU32~50 Standard Cylinder SU32X650 with the SAU32X650
To replace this SU32X650, order the SAU32X650, confirming the 32mm bore, 650mm stroke, 1/8 port, M10x1.25 rod thread, and SC-series mounting. Because this SKU has no magnet, it cannot hold a sensor; if detection is needed, specify an SAU-S model and use CMSG/DMSG/EMSG switches. For load holding, note that a standard cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot check valve. With a 650mm stroke, prevent rod bending by guiding the load externally. If 402N at 0.5MPa is insufficient, step up to a 40mm bore (628N); if oversizing, a 25mm stroke reduces space. The SAUF variant adds a built-in valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU32X650
- ✓ 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 SU32X650 FAQ
Yes, the SU32X650 is end-of-life. The direct replacement is the AirTAC SAU32X650. It matches the 32mm bore, 650mm stroke, 402N force at 0.5MPa, 1/8 port, and SC-series mounting accessories. You can install the SAU without modifying the machine.
The 32mm bore provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. This specific SKU lacks a magnet, so it cannot accept a sensor. The SAU replacement supports CMSG/DMSG/EMSG switches if you order the -S magnet version.
