This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X500, 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 SU40X500
The AirTAC Airtac SU32~50 Standard Cylinder SU40X500 is a double-acting profile-type standard cylinder with a Ø40mm bore and 500mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X500, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X500
The AirTAC SU40X500 is a discontinued double-acting profile-type cylinder with a 40mm bore and 500mm stroke. Delivering 628N push force at 0.5MPa via a 1/4" port, it is replaced directly by the SAU40X500. This direct upgrade matches the original body, M12x1.25 rod thread, force class, and SC-series mounting accessories exactly.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU40X500 upgrade modernizes sensing to CMSG/DMSG/EMSG switches if you add an -S option, and introduces the SAUF built-in-valve variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X500 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 SAU40X500 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 SU40X500 Is Used
Vertical Lift Gate
Raises a 32kg access panel using the 628N push force at 0.5MPa, requiring an external check valve to hold the load safely.
Material Ejection
Cycles parts out of a machining area at 30-800mm/s, relying on the 21mm adjustable cushions to decelerate the 500mm travel.
Replacing the Airtac SU32~50 Standard Cylinder SU40X500 with the SAU40X500
To replace this discontinued SU40X500, order the SAU40X500 direct equivalent, verifying your 1/4" port, PT/G/NPT thread choice, and SC-series mounting (LB/FA/FB/CA/CB). This non-magnetic SKU cannot hold a position sensor; if you need detection on the new SAU, specify the -S magnet and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For the 500mm stroke, prevent rod bending by using an external guide to absorb side loads. If checking neighbouring bores, a 32mm bore offers 402N push at 0.5MPa while a 50mm bore provides 982N. Note that air cushions only decelerate the load; use an external rod lock or pilot-operated check valve for secure holding.
Replacement checklist
- ✓ Same bore / stroke → SAU40X500
- ✓ 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 SU40X500 FAQ
Yes, the AirTAC SU40X500 is discontinued. The direct replacement is the SAU40X500. It shares the identical 40mm bore, 500mm stroke, 628N force, 1/4" port, and SC-series mounting, so it fits your existing assembly directly.
At 0.5MPa it provides 628N push and 528N pull force, increasing to 879N push at 0.7MPa, with a theoretical max of 128kgf at 1.0MPa. This specific non-magnetic SKU cannot accept a sensor; the SAU replacement requires an -S option and uses CMSG/DMSG/EMSG switches.
