This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X410, 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 SU40X410
The AirTAC SU32~50 Standard Cylinder SU40X410 is a double-acting profile-type standard cylinder with a Ø40mm bore and 410mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X410, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X410
The AirTAC SU40X410 is a discontinued double-acting profile-type cylinder with a 40mm bore and 410mm stroke. It delivers 628N push and 528N pull at 0.5MPa via a 1/4" port. The direct replacement is the SAU40X410, matching the bore, stroke, force, port and SC-series mounting.
This SKU lacks a magnet and cannot accept a sensor, whereas the SAU upgrade supports CMSG/DMSG/EMSG switches and a SAUF built-in valve option. The 410mm stroke requires external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X410 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 SAU40X410 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 SU40X410 Is Used
Package Diverting
Pushes light to medium cartons at 90 degrees on a sorting line, utilizing the 628N push force and 410mm reach to clear adjacent lanes.
Pallet Stopper Gate
Acts as a retractable stop for pallets entering a stretch wrapper, with the long stroke providing ample clearance for varying load widths.
Component Ejection
Ejects machined aluminum parts from a fixture, using the 528N pull force to retract the 16mm rod safely behind a machine guard.
Replacing the Airtac SU32~50 Standard Cylinder SU40X410 with the SAU40X410
To replace this discontinued SU40X410, order the SAU40X410 direct equivalent. Confirm the 1/4" port, M12x1.25 rod thread, PT/G/NPT thread choice, and SC-series mounting. Because this SKU has no magnet (-S), it cannot take a sensor; if sensing is needed, order the SAU40X410-S and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For sizing, the neighboring 32mm bore yields 402N push at 0.5MPa, while the 50mm bore yields 982N. A plain cylinder drifts on air loss—the 21mm cushions only decelerate—so use an external rod lock or pilot-operated check valve for load holding. At 410mm stroke, use external guides to prevent rod bending. The SAUF valve-integrated variant is available if you need a self-switching cylinder.
Replacement checklist
- ✓ Same bore / stroke → SAU40X410
- ✓ 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 SU40X410 FAQ
Yes, the AirTAC SU40X410 is discontinued and end-of-life. The direct replacement is the SAU40X410. It shares the identical 40mm bore, 410mm stroke, 1/4" port, output force, and SC-series mounting accessories, so it fits the same application directly.
At 0.5MPa it pushes 628N and pulls 528N; at 0.7MPa it pushes 879N, and the theoretical max is 128kgf at 1.0MPa. The 1/4" port cylinder runs 30-800mm/s. It cannot hold a load without live air, as the 21mm cushions only decelerate; use an external rod lock for holding.
