This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X165S, 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 SU32X165S is a double-acting profile-type standard cylinder with a Ø32mm bore and 165mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X165S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X165S is a discontinued double-acting profile-type cylinder with a 32 mm bore and 165 mm stroke. It delivers 402 N push force at 0.5 MPa through a 1/8 inch port. The direct replacement is the SAU32X165S, matching the bore, stroke, output, and SC-series mounting.
This compact extruded-aluminum body is shorter than an ISO 15552 equivalent. The SAU upgrade switches the legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches and adds the SAUF built-in-valve option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X165S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X165S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×165 | 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.
Uses the 402 N push force at 0.5 MPa to reliably push lightweight molded components out of a machining fixture.
Actuates a routing gate on a packaging line, where the 165 mm stroke provides exact travel for sorting small boxes.
To replace this SU32X165S, order the SAU32X165S. Verify your 1/8 inch port, M10x1.25 rod thread, and SC-series mounting. Because this SKU has the -S magnet, note that the SAU requires CMSG/DMSG/EMSG switches instead of the old CS1-B/DS1-B. If sizing neighbors, a 40 mm bore yields 628 N push at 0.5 MPa, while dropping pressure to 0.5 MPa gives 402 N here. For any held load, add an external rod lock or pilot-operated check valve, as the cushion only decelerates. The 165 mm stroke is under the 300 mm side-load threshold, but always guide the rod to prevent bending.
Replacement checklist
Yes, the SU32X165S is discontinued. The direct replacement is the SAU32X165S. It matches the 32 mm bore, 165 mm stroke, 402 N force, 1/8 inch port, and SC-series mounting. You also gain the SAUF built-in-valve option.
The SAU32X165S provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Because your old model has the -S magnet, the SAU replacement uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X165S replacement — usually within 7-8 hours.
