This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X1050S, 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 SU32X1050S
The AirTAC SU32~50 Standard Cylinder SU32X1050S is a double-acting profile-type standard cylinder with a Ø32mm bore and 1050mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X1050S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X1050S
The AirTAC SU32X1050S is a discontinued double-acting profile-type cylinder with a 32 mm bore and a 1050 mm stroke. Because 1050 mm exceeds the 1000 mm standard maximum for this bore, it is a non-standard, made-to-order length. It delivers 402 N push force at 0.5 MPa via a 1/8" port. AirTAC replaced the SU line with the SAU family; the SAU32X1050S is the direct replacement, matching the bore, stroke, output force, port size, and SC-series mounting.
The SAU upgrade retains the compact extruded aluminum body—shorter than a same-bore ISO 15552 cylinder—but switches to current CMSG/DMSG/EMSG sensors, whereas this legacy SU used CS1-B/DS1-B switches. The new SAUF variant also adds a built-in 4M solenoid valve the SU never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X1050S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X1050S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU32X1050S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×1050 | Stroke length in mm. |
| -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 SU32X1050S Is Used
Extended Reach Diverters
Drives long-travel sorting arms on packaging lines where a 1050 mm reach is needed to push cartons between parallel conveyor belts.
High-Bay Ejection
Ejects lightweight totes from deep storage lanes, utilizing the 402 N push force to clear obstructions over a 1-meter travel distance.
Pallet Transfer Stops
Acts as a long-stroke pop-up stopper to halt pallets at varying heights, requiring external guides to support the extended 12 mm rod.
Replacing the Airtac SU32~50 Standard Cylinder SU32X1050S with the SAU32X1050S
To replace this SU32X1050S, order the SAU32X1050S direct equivalent. Verify your 1/8" port thread (PT, G, or NPT) and SC-series mounting accessories (LB, FA, FB, CA, CB, TC). Because this unit has the -S magnet, note that your legacy CS1-B/DS1-B switches must change to the SAU's CMSG/DMSG/EMSG sensor family. If you need load holding, remember the air cushion only decelerates; add an external rod lock or pilot-operated check valve to prevent drift. At 1050 mm, this non-standard stroke requires an external guide to prevent rod bending under side loads. If you need more force, the 40 mm bore offers 628 N push at 0.5 MPa; if less is acceptable, check smaller bores.
Replacement checklist
- ✓ Same bore / stroke → SAU32X1050S
- ✓ 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 SU32X1050S FAQ
Yes, the SU32X1050S is discontinued. The direct replacement is the AirTAC SAU32X1050S. It offers identical 32 mm bore, 1050 mm stroke, port size, and SC-series mounting compatibility, so it fits the same application without mechanical modifications.
At 0.5 MPa it provides 402 N push and 345 N pull force; at 0.7 MPa it pushes 563 N, with a theoretical max of 82 kgf at 1.0 MPa. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; when upgrading to the SAU replacement, you must use the current CMSG/DMSG/EMSG sensor family.
