This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X470S, 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 SU40X470S
The AirTAC SU32~50 Standard Cylinder SU40X470S is a double-acting profile-type standard cylinder with a Ø40mm bore and 470mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X470S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X470S
The AirTAC SU40X470S is a discontinued double-acting profile cylinder featuring a 40mm bore, 470mm stroke, and a 1/4" port. Generating 628N push force at 0.5MPa, its direct replacement is the SAU40X470S, which preserves the original bore, stroke, output force, and SC-series mounting compatibility.
This extruded aluminium profile body is more compact than an ISO 15552 equivalent. The SAU upgrade switches the legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors and introduces the SAUF built-in valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X470S 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 SAU40X470S 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 SU40X470S Is Used
Package Diverting
Pushes light to medium cartons on a sorting line using a 470mm extension, safely operating within the 377N working load limit.
Pallet Positioning
Shifts empty pallets into alignment at a wrapping station, taking advantage of the compact 40mm profile body to fit tight frames.
Light Press Downstroke
Provides a steady 628N downward clamping force at 0.5MPa for assembling small components, requiring external guides for the long rod.
Replacing the Airtac SU32~50 Standard Cylinder SU40X470S with the SAU40X470S
To replace this discontinued SU40X470S, order the SAU40X470S direct equivalent, verifying your 1/4" port, M12x1.25 rod thread, and SC-series mounting. If sizing alternatives, the adjacent 32mm bore yields 402N push at 0.5MPa, while the 50mm bore provides 982N. For the 470mm stroke, use external guides to prevent rod bending under side loads. The -S magnet means your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. Note that air cushions only decelerate; use an external rod lock or pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU40X470S
- ✓ 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 SU40X470S FAQ
Yes, the SU40X470S is discontinued. The direct replacement is the SAU40X470S. It matches the 40mm bore, 470mm stroke, 1/4" port, output force, and SC-series mounting, so it fits the same application directly.
The 40mm bore provides 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a 128kgf maximum at 1.0MPa. Because this SU40X470S has a magnet, its legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU upgrade.
