This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X260, 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 SU40X260
The AirTAC Airtac SU32~50 Standard Cylinder SU40X260 is a double-acting profile-type standard cylinder with a Ø40mm bore and 260mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X260, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X260
The AirTAC SU40X260 is a discontinued double-acting profile cylinder with a 40mm bore and 260mm stroke. It delivers 628N push force at 0.5MPa via a 1/4" port. AirTAC replaced it with the SAU40X260 direct replacement, maintaining the exact body, stroke, force, and SC-series mounting.
This extruded profile is shorter than an ISO 15552 cylinder of the same bore. Since this SKU lacks a magnet, it cannot take a sensor; the SAU upgrade supports CMSG/DMSG/EMSG switches and adds a SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X260 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X260 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 SU40X260 Is Used
Package Diverting
Actuates diverter arms on packaging lines, using the 628N push force at 0.5MPa to push cartons reliably without overshooting.
Small Part Ejection
Ejects molded parts or sorted goods from workstation chutes, where the 260mm stroke provides adequate reach into bins.
Clamp Actuation
Drives lightweight clamping mechanisms in assembly fixtures, relying on the 528N pull force to hold components securely.
Replacing the Airtac SU32~50 Standard Cylinder SU40X260 with the SAU40X260
To replace this discontinued SU40X260, order the SAU40X260. Verify your 1/4" port thread (PT/G/NPT), M12x1.25 rod end, and SC-series mounting (LB/FA/FB/CA/CB). Because this specific SKU has no -S magnet, it cannot accept a sensor; if sensing is needed, the SAU replacement requires CMSG/DMSG/EMSG switches. For loads needing holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. If sizing alternatives, a 32mm bore offers 402N push at 0.5MPa, while a 50mm bore provides 982N. With the 260mm stroke, ensure guide rails prevent rod bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU40X260
- ✓ 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 SU40X260 FAQ
Yes, the AirTAC SU40X260 is discontinued. The direct replacement is the SAU40X260. It shares the same 40mm bore, 260mm stroke, 628N force, 1/4" port, and SC-series mounting accessories, so it fits the same application.
The bore 40mm cylinder provides 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a 128kgf max at 1.0MPa. This specific SKU lacks a magnet and cannot take a sensor. The SAU replacement uses CMSG/DMSG/EMSG switches.
