This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X1500S, 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 SU32X1500S
The AirTAC SU32~50 Standard Cylinder SU32X1500S is a double-acting profile-type standard cylinder with a Ø32mm bore and 1500mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X1500S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X1500S
The AirTAC SU32X1500S is a discontinued double-acting profile-type cylinder with a 32 mm bore and a 1500 mm stroke. Because 1500 mm exceeds the 1000 mm standard maximum for this bore, this unit is a non-standard, made-to-order configuration. As a compact extruded-aluminium profile, it is shorter than an ISO 15552 cylinder of the same bore and uses a 1/8" port.
AirTAC replaced the SU line with the SAU family. The direct replacement is the SAU32X1500S, matching the bore, stroke, output force, 1/8" port, and SC-series mounting accessories. The upgrade switches the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches, and the SAU line introduces a SAUF variant with a built-in 4M solenoid valve that the SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X1500S 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 SAU32X1500S 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 SU32X1500S Is Used
Long-Reach Diversion
Pushes light packages across a wide transfer zone using the full 1500 mm travel, relying on external guides to support the extended 12 mm rod.
High-Bay Ejection
Ejects totes from deep racking where a compact 32 mm profile body saves space, delivering 402 N push at 0.5 MPa to clear the shelf.
Linear Indexing
Moves small jigs along a long axis, using the 1/8" port for fast cycling and CMSG sensors on the SAU replacement for precise end-position detection.
Replacing the Airtac SU32~50 Standard Cylinder SU32X1500S with the SAU32X1500S
To replace this discontinued SU32X1500S, order the SAU32X1500S direct equivalent, verifying the 32 mm bore, 1500 mm non-standard stroke, 1/8" port, M10x1.25 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU includes the -S magnet, you must upgrade your sensing setup: the old CS1-B/DS1-B switches are obsolete, and the SAU replacement requires CMSG/DMSG/EMSG sensors. A 1500 mm stroke on a 12 mm rod is highly susceptible to side-load and rod-bending, so an external guide is strongly recommended to prevent premature seal failure. If sizing alternatives, a neighbouring 40 mm bore offers higher force (628 N push at 0.5 MPa), while the 32 mm class itself is limited to 82 kgf at 1.0 MPa. Note that this cylinder cannot hold a load without live air—the cushions only decelerate—so add an external rod lock or pilot-operated check valve for vertical holding. For faster cycling without external valves, consider the SAUF built-in-valve option.
Replacement checklist
- ✓ Same bore / stroke → SAU32X1500S
- ✓ 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 SU32X1500S FAQ
Yes, the AirTAC SU32X1500S is discontinued and end-of-life. The direct replacement is the SAU32X1500S. It provides identical performance with the same 32 mm bore, 1500 mm stroke, output force, 1/8" port, and SC-series mounting. You can swap it directly without modifying your machine.
The 32 mm bore provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa. Because this is a -S magnet model, note that the legacy CS1-B/DS1-B switches are obsolete; the SAU32X1500S replacement uses current CMSG/DMSG/EMSG sensors.
