This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X110, 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 SU40X110
The AirTAC Airtac SU32~50 Standard Cylinder SU40X110 is a double-acting profile-type standard cylinder with a Ø40mm bore and 110mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X110, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X110
The AirTAC SU40X110 is a discontinued double-acting profile-type cylinder with a 40mm bore and 110mm stroke. It delivers 628 N push force at 0.5 MPa. AirTAC replaced this unit with the SAU40X110, a direct alternative retaining the exact 1/4" port, M12x1.25 rod thread, and SC-series mounting compatibility.
The SAU upgrade keeps the body dimensions unchanged but moves sensing to the modern CMSG/DMSG/EMSG switches (this base SU SKU lacks a magnet and cannot accept any sensor). The SAU family also introduces the SAUF variant with a built-in valve, an option the legacy SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X110 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 SAU40X110 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 SU40X110 Is Used
Package Diverting
Pushes light to medium cartons on a 110mm stroke at sorting stations, utilising the 628 N push force to reliably redirect goods without damaging packaging.
Pallet Stops
Acts as a compact pneumatic stop on low-profile roller conveyors, where the 40mm profile body saves space compared to older ISO standards.
Component Clamping
Secures workpieces for machining or assembly operations, providing stable 528 N pull force at 0.5 MPa for reliable holding during secondary processes.
Replacing the Airtac SU32~50 Standard Cylinder SU40X110 with the SAU40X110
To replace the SU40X110, order the SAU40X110. Verify your 1/4" port thread (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, TC) so the new cylinder drops straight in. Because this specific SKU has no -S magnet, it cannot support position sensing; if you need switches on the SAU replacement, you must select the -S option and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For loads requiring holding without live air, add an external rod lock or pilot-operated check valve, as the adjustable cushions only decelerate. If your 628 N @0.5 MPa output is insufficient, step up to the 50mm bore (982 N); if excessive, drop to the 32mm bore (402 N).
Replacement checklist
- ✓ Same bore / stroke → SAU40X110
- ✓ 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 SU40X110 FAQ
Yes, the SU40X110 is discontinued. The direct replacement is the AirTAC SAU40X110. It shares the identical 40mm bore, 110mm stroke, 628 N force at 0.5 MPa, 1/4" port, and SC-series mounting, so it fits the same application without mechanical modifications.
The 40mm bore features a 1/4" air port. It generates 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, 1130 N push at 0.9 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
