This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X430, 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 SU40X430
The AirTAC SU32~50 Standard Cylinder SU40X430 is a double-acting profile-type standard cylinder with a Ø40mm bore and 430mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X430, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X430
The AirTAC SU40X430 is a discontinued double-acting profile-type standard cylinder with a 40 mm bore and 430 mm stroke. It delivers 628 N push and 528 N pull at 0.5 MPa, operating at 30-800 mm/s through a 1/4" port. AirTAC replaced this end-of-line unit with the SAU40X430 direct replacement, retaining the exact extruded aluminium body, M12x1.25 rod thread, 21 mm cushions and SC-series mounts.
This shorter-than-ISO profile body saves space while matching legacy SC accessories. This specific SKU lacks a magnet, so it cannot accept sensors; the SAU upgrade adds CMSG/DMSG/EMSG switch compatibility and a SAUF built-in-valve option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X430 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 SAU40X430 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 SU40X430 Is Used
Package Diversion
Pushes medium-weight cartons off a sorting line using the 628 N push force at 0.5 MPa, with the 430 mm stroke clearing adjacent lanes.
Pallet Stopper Gate
Acts as a pneumatic stop for inbound pallets, handling the impact via adjustable end cushions before releasing goods downstream.
Component Ejection
Ejects machined aluminium parts from a fixture, safely moving loads under 377 N without overstressing the 16 mm piston rod.
Replacing the Airtac SU32~50 Standard Cylinder SU40X430 with the SAU40X430
To replace this discontinued SU40X430, order the SAU40X430 with the same 40 mm bore, 430 mm stroke, 1/4" port (PT/G/NPT thread) and SC-series mounting hardware. Because this SKU has no -S magnet, it cannot take a sensor; if you need position detection on the SAU, specify the -S option and migrate to CMSG/DMSG/EMSG switches from the old CS1-B/DS1-B family. For loads needing holding on air loss, add an external rod lock or pilot-operated check valve, as the 21 mm cushions only decelerate. With a 430 mm stroke, use an external guide to prevent rod bending and side loads. If you need more force, the 50 mm bore yields 982 N push at 0.5 MPa; if less is acceptable, the 32 mm bore provides 402 N.
Replacement checklist
- ✓ Same bore / stroke → SAU40X430
- ✓ 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 SU40X430 FAQ
Yes, the AirTAC SU40X430 is discontinued. The direct replacement is the SAU40X430. It matches the 40 mm bore, 430 mm stroke, 628 N force at 0.5 MPa, 1/4" port and SC-series mounting. You just swap the cylinder with no mechanical changes.
The 40 mm bore delivers 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and a theoretical max of 128 kgf at 1.0 MPa. This specific SKU has no magnet and cannot accept sensors. The SAU40X430 replacement supports CMSG/DMSG/EMSG switches if you order the -S variant.
