This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X1500SN, 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 SU40X1500SN
The AirTAC SU32~50 Standard Cylinder SU40X1500SN 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 SAU40X1500SN, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X1500SN
The AirTAC SU40X1500SN is a discontinued double-acting profile-type cylinder with a 40mm bore and 1500mm stroke. Because 1500mm exceeds the 1200mm standard maximum for this bore, it is a non-standard, made-to-order unit. It delivers 628N push force at 0.5MPa via a 1/4" port. The direct replacement is the SAU40X1500SN, matching the body, stroke, force, and SC-series mounts.
This unit includes a piston magnet (-S) for legacy CS1-B/DS1-B switches; the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The -N NBR seal supports -20 to +70C. Note the SAU line adds a SAUF built-in-valve variant the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X1500SN 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 SAU40X1500SN 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 SU40X1500SN Is Used
Long-Reach Diversion
Pushes packages across a wide conveyor belt using the full 1500mm stroke, relying on external guides to prevent rod bending during the extended travel.
High-Bay Storage Retrieval
Extracts totes from deep shelving units where the 628N push force at 0.5MPa easily handles standard container weights up to 32kg with a safe margin.
Extended Stroke Assembly
Actuates tooling carriages over a long linear path, taking advantage of the compact profile body and adjustable 21mm cushions at both ends.
Replacing the Airtac SU32~50 Standard Cylinder SU40X1500SN with the SAU40X1500SN
To replace this SU with the SAU40X1500SN, verify the 40mm bore, 1500mm stroke, 1/4" port, M12x1.25 rod thread, and SC-series mounting. The -S magnet means you must switch from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. For sizing both ways: a 32mm bore offers 402N push at 0.5MPa (smaller), while a 50mm bore provides 982N (larger). At 0.7MPa this 40mm bore pushes 879N. Because this is a 1500mm non-standard stroke exceeding the 1200mm max, external guides are critical to prevent rod bending under side loads. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock for held loads. The SAUF valve-integrated option is available if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU40X1500SN
- ✓ 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 SU40X1500SN FAQ
Yes, the SU40X1500SN is discontinued. The direct replacement is the SAU40X1500SN, which matches the 40mm bore, 1500mm stroke, 628N force, 1/4" port, and SC-series mounting. You simply order the SAU equivalent.
The 40mm bore delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. The -S magnet works with legacy CS1-B/DS1-B switches; on the SAU replacement, you must use CMSG/DMSG/EMSG sensors.
