This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X65S, 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 Airtac SU32~50 Standard Cylinder SU32X65S is a double-acting profile-type standard cylinder with a Ø32mm bore and 65mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X65S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X65S is a discontinued double-acting profile-type cylinder with a 32mm bore and 65mm stroke. Delivering 402N push force at 0.5MPa, it features an extruded aluminium barrel and adjustable cushions, making it more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this with the SAU32X65S, a direct upgrade retaining the exact bore, stroke, force, 1/8" port and SC-series mounting.
The -S suffix means it has a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement switches to current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF built-in-valve variant the SU lacked. A plain cylinder drifts without live air, so use a rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X65S 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 SAU32X65S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 402N push force at 0.5MPa to reliably push lightweight machined components out of a fixture on an automated line.
The compact 32mm profile and 65mm stroke actuate a short diverter arm to sort small parcels on a conveyor belt.
Provides secondary clamping pressure for thin material workholding, where the 20kg vertical lift capacity is sufficient.
To replace this SU32X65S, order the SAU32X65S. Confirm your 1/8" port thread (PT/G/NPT), M10x1.25 rod end, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU has the -S magnet, note that your legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU. If you need self-switching, explore the SAUF valve-integrated variant. For sizing both ways: a 40mm bore yields 628N push @0.5MPa, while dropping to a smaller bore reduces force. The 65mm stroke is under the 1000mm standard max, so no side-load guide is required. Remember, the air cushion only decelerates; it does not hold loads on air loss—install a pilot-operated check valve for vertical holding.
Replacement checklist
Yes, the AirTAC SU32X65S is discontinued. The direct replacement is the SAU32X65S. It shares the same 32mm bore, 65mm stroke, 402N output force, 1/8" port, and SC-series mounting accessories, so it fits the same application directly.
The SAU32X65S matches the SU forces: 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N at 0.9MPa, and 82kgf max at 1.0MPa. The key upgrade is sensors: if you used the -S magnet with legacy CS1-B/DS1-B switches, you must switch to current CMSG/DMSG/EMSG sensors on the SAU.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X65S replacement — usually within 7-8 hours.
