This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X1600, 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 SU40X1600 is a double-acting profile-type standard cylinder with a Ø40mm bore and 1600mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X1600, which matches its bore, stroke, force and mounting.
The AirTAC SU40X1600 is a discontinued double-acting profile-type cylinder with a 40mm bore and 1600mm stroke. It delivers 628N push and 528N pull at 0.5MPa via a 1/4" port. The direct replacement is the SAU40X1600, matching the body, force, port, and SC-series mounting.
This 1600mm stroke exceeds the 1200mm standard maximum, making it a made-to-order item requiring external guides to prevent rod bending. Because this SKU lacks a magnet, it cannot take a sensor. The SAU upgrade adds CMSG/DMSG/EMSG sensors and a SAUF valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X1600 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| Max (@1.0 MPa) | 128 kgf | |
The SAU40X1600 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 workpieces between distant processing stations on a wide conveyor belt using its 1600mm reach.
Actuates a long extending arm to index pallets into deep storage racking without occupying floor space.
Ejects machined parts from a deep work area, clearing the entire 1600mm envelope in one cycle.
To replace this discontinued SU40X1600, order the SAU40X1600 direct equivalent, confirming the 1/4" port, M12x1.25 rod thread, and SC-series mounting. Since 1600mm exceeds the 1200mm standard stroke, it is non-standard and requires external guides to prevent rod bending over that length. If sizing down, a 32mm bore offers 402N push at 0.5MPa; sizing up to 50mm yields 982N. This no-magnet SKU cannot support sensing, whereas the SAU accepts CMSG/DMSG/EMSG switches. The cylinder does not hold load without air; use an external rod lock for vertical holding. The SAUF variant integrates a valve the SU lacked.
Replacement checklist
Yes, the AirTAC SU40X1600 is discontinued and end-of-life. The direct replacement is the SAU40X1600. It shares the same 40mm bore, 1600mm stroke, 628N output force at 0.5MPa, 1/4" port, and SC-series mounting accessories, fitting the same application directly.
It provides 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, 1130N at 0.9MPa, and a 128kgf max at 1.0MPa. This specific SKU has no magnet, so it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches. Note the 1600mm stroke is non-standard and requires external guides.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU40X1600 replacement — usually within 7-8 hours.
