This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X1000S, 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 SU40X1000S
The AirTAC SU32~50 Standard Cylinder SU40X1000S is a double-acting profile-type standard cylinder with a Ø40mm bore and 1000mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X1000S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X1000S
The AirTAC SU40X1000S is a discontinued double-acting profile cylinder with a 40mm bore and 1000mm stroke, delivering 628N push force at 0.5MPa. AirTAC replaced this end-of-line unit with the SAU40X1000S, a direct alternative retaining the exact bore, stroke, 1/4" port, M12x1.25 rod thread and SC-series mounting. The extruded aluminium body is shorter than an ISO 15552 cylinder of the same bore.
Because this SKU includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches; the SAU replacement upgrades to current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF valve-integrated option, which the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X1000S 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 SAU40X1000S 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 SU40X1000S Is Used
Long-Stroke Diversion
Pushes packages across a 1-meter transfer lane using the 628N force at 0.5MPa, guided externally to prevent rod bending on the 1000mm extension.
Linear Indexing
Shifts a machining pallet 1000mm between stations, using the 21mm adjustable air cushions at both ends to decelerate the 40mm bore smoothly.
Replacing the Airtac SU32~50 Standard Cylinder SU40X1000S with the SAU40X1000S
To replace this discontinued SU40X1000S, order the SAU40X1000S. Confirm the 1/4" port (default PT, with G or NPT available), M12x1.25 rod thread, and your SC-series mounting (LB/FA/FB/CA/CB). If sizing alternatives, a 32mm bore yields 402N push at 0.5MPa, while a 50mm bore yields 982N. Because this is a 1000mm stroke, use external guides to prevent rod bending and side-load damage. Note the -S magnet requires switching from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock for held loads. The SAUF variant adds a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU40X1000S
- ✓ 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 SU40X1000S FAQ
Yes, the AirTAC SU40X1000S is discontinued. The direct replacement is the SAU40X1000S. It matches the 40mm bore, 1000mm stroke, 628N force, 1/4" port and SC-series mounting. The body is unchanged, but the -S magnet now requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 40mm bore uses a 1/4" port. At 0.5MPa it provides 628N push and 528N pull force. This increases to 879N push at 0.7MPa, 1130N push at 0.9MPa, and a theoretical max of 128kgf at 1.0MPa. The rod is 16mm with an M12x1.25 thread, operating at 30-800mm/s.
