This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X585S, 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 SU32X585S
The AirTAC SU32~50 Standard Cylinder SU32X585S is a double-acting profile-type standard cylinder with a Ø32mm bore and 585mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X585S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X585S
The AirTAC SU32X585S is a discontinued double-acting profile-type cylinder featuring a 32mm bore and 585mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. AirTAC replaced this legacy unit with the SAU32X585S, a direct equivalent retaining the exact bore, stroke, output force, and SC-series mounting footprint.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the SU's legacy CS1-B/DS1-B switches, and offers a new SAUF built-in-valve option. Note that standard cylinders drift without live air; use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X585S 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 SAU32X585S 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 SU32X585S Is Used
Bin Push-Off
Ejects parts from storage bins using the 32mm bore's 20kg vertical lift capacity, relying on external guides for the long stroke.
Light Assembly Transfer
Moves delicate sub-components between stations where the 1/8" port and 30-800mm/s speed provide precise pneumatic control.
Replacing the Airtac SU32~50 Standard Cylinder SU32X585S with the SAU32X585S
To replace this SU32X585S, order the SAU32X585S by confirming the 32mm bore, 585mm stroke, 1/8" port, and M10x1.25 rod thread. If your machine used the SU's -S magnet for position sensing, you must upgrade to the SAU's CMSG/DMSG/EMSG switch family. When sizing, neighboring bores (40mm) offer higher force (628N push at 0.5MPa), while this 32mm bore provides 402N. Because the 585mm stroke invites rod bending, use external guides to prevent side-load damage. For load holding during air loss, add a pilot-operated check valve, as cushions only decelerate. The SAUF variant adds a built-in 4M solenoid valve if self-switching is needed.
Replacement checklist
- ✓ Same bore / stroke → SAU32X585S
- ✓ 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 SU32X585S FAQ
Yes, the SU32X585S is discontinued. The direct replacement is the AirTAC SAU32X585S. It matches the 32mm bore, 585mm stroke, 402N force, 1/8" port, and SC-series mounting, so it drops right into the same application.
The 32mm bore provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and an 82kgf max at 1.0MPa. Because this SU32X585S has a -S magnet, it used legacy CS1-B/DS1-B switches; the SAU32X585S replacement requires the current CMSG/DMSG/EMSG sensor family.
