This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X1500, 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.

The AirTAC SU32~50 Standard Cylinder SU40X1500 is a double-acting profile-type standard cylinder with a Ø40mm bore and 1500mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X1500, which matches its bore, stroke, force and mounting.
The AirTAC SU40X1500 is a discontinued double-acting profile-type cylinder with a 40mm bore and 1500mm stroke. Delivering 628N push and 528N pull at 0.5MPa, it uses an extruded aluminium barrel and adjustable air cushions at both ends. Because 1500mm exceeds the 1200mm standard maximum for this bore, this unit is a non-standard, made-to-order configuration. The direct replacement is the SAU40X1500, matching the force, 1/4" port, M12x1.25 rod thread and SC-series mounting.
When upgrading, note that the SAU family uses current CMSG/DMSG/EMSG sensors, whereas this legacy SU had no magnet and cannot accept a switch. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered. At 1500mm, external guides are recommended to prevent rod bending.

The SAU40X1500 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.
Pushes packages across a wide sorting conveyor belt using the full 1500mm extension, relying on external guides to prevent rod deflection.
Extracts totes from deep shelving racks where the 628N push force at 0.5MPa handles loaded inventory boxes safely.
Transfers workpieces between distant machine stations, benefiting from the compact 40mm profile body to save floor space.
To replace this SU40X1500, order the SAU40X1500 direct equivalent, verifying your 1/4" port, M12x1.25 rod thread, PT/G/NPT thread standard and SC-series mounting (LB/FA/FB/CA/CB). This SKU lacks a magnet (-S) and cannot support sensing; if you need position detection on the new cylinder, specify an SAU40X1500S and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. Because 1500mm is a non-standard stroke exceeding the 1200mm maximum, expect made-to-order lead times and ensure external guides are fitted to manage side loads and prevent rod bending. For load holding, do not rely on the air cushion—it only decelerates; add an external rod lock or pilot-operated check valve. If you need more force, the 50mm bore offers 982N push at 0.5MPa; if less is acceptable, the 32mm bore provides 402N. The SAUF valve-integrated version can simplify plumbing if you need self-switching.
Replacement checklist
Yes, the SU40X1500 is discontinued. The direct replacement is the AirTAC SAU40X1500. It matches the 40mm bore, 1500mm stroke, 628N push force at 0.5MPa, 1/4" port, and SC-series mounting accessories. You can install it directly into the same application.
The bore is 40mm with a 1/4" port. It provides 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. This specific SKU has no magnet, so it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches if sensing is required.
