This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X125, 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 SU32X125
The AirTAC SU32~50 Standard Cylinder SU32X125 is a double-acting profile-type standard cylinder with a Ø32mm bore and 125mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X125, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X125
The AirTAC SU32X125 is a discontinued double-acting profile cylinder with a 32mm bore and 125mm stroke. Delivering 402N push force at 0.5MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same bore. The direct replacement is the SAU32X125, matching the exact bore, stroke, output force, 1/8" port, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade adds a built-in valve option (SAUF) and uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X125 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 SAU32X125 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 SU32X125 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight machined components out of a fixture on an automated line.
Package Diverting
Actuates a short 125mm stroke diverter arm to route small boxes on a conveyor, fitting neatly into compact machinery frames.
Bin Gating
Opens and closes small parts bin gates, where the 20kg safe vertical lift capacity is sufficient to manage gravity-fed stock flow.
Replacing the Airtac SU32~50 Standard Cylinder SU32X125 with the SAU32X125
To replace this SU32X125, order the SAU32X125 direct equivalent, confirming the 1/8" port, M10x1.25 rod thread, and SC-series mounting. Since this non-magnetic SKU cannot take a switch, no sensor migration is needed, but the SAU family supports CMSG/DMSG/EMSG switches if you add an -S suffix. At 125mm stroke, side-load risks are low, but ensure rigid guidance for the 12mm rod. For higher loads, a 40mm bore provides 628N push at 0.5MPa. Note that a plain cylinder drifts on air loss; the 21mm cushions only decelerate near stroke ends, so use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU32X125
- ✓ 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 SU32X125 FAQ
Yes, the AirTAC SU32X125 is discontinued and end-of-life. The direct replacement is the SAU32X125. It shares the identical 32mm bore, 125mm stroke, output force, 1/8" port, and SC-series mounting accessories, so it fits the same application without modification.
The 32mm bore generates 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor. If sensing is required, the SAU32X125-S replacement uses current CMSG/DMSG/EMSG switches instead of the older CS1-B/DS1-B.
