This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X15, 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 SU32X15 is a double-acting profile-type standard cylinder with a Ø32mm bore and 15mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X15, which matches its bore, stroke, force and mounting.
The AirTAC SU32X15 is a discontinued double-acting profile-type cylinder with a 32 mm bore and a nonstandard 15 mm stroke. It delivers 402 N push and 345 N pull at 0.5 MPa. AirTAC replaced this legacy unit with the SAU32X15 direct replacement, retaining the exact 1/8" port, M10x1.25 rod thread, output force and SC-series mounting. You simply order the SAU32X15 to maintain your machine footprint.
Because this 15 mm stroke is shorter than the 25 mm minimum standard, it is flagged as a nonstandard_stroke. This SKU lacks a magnet (-S), so it cannot accept a sensor; furthermore, the SAU upgrade transitions to CMSG/DMSG/EMSG switches, and introduces the SAUF built-in-valve variant the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X15 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X15 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.
Provides a rapid 30-800 mm/s ejection pulse for lightweight 20 kg assemblies, fitting neatly into tight tooling spaces using standard SC-series mounts.
Drives small pneumatic diverter gates with a 345 N pull force at 0.5 MPa, offering precise flow control in compact packaging machinery.
To replace this discontinued SU32X15, order the SAU32X15. Confirm your 1/8" port thread (PT, G or NPT) and SC-series mounting (LB/FA/FB/CA/CB) to ensure a direct fit. Since this is a nonstandard 15 mm stroke (below the 25 mm standard minimum), verify if a 25 mm stroke can be tolerated or if a custom shortened SAU32X15 is required. This bare SKU has no magnet and cannot accept a sensor; if sensing is needed, you must step up to an SAU32X15S and update to CMSG/DMSG/EMSG switches. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for held loads. For any stroke application under 300 mm, side-load risks are minimal but ensure straight alignment to avoid rod bending.
Replacement checklist
Yes, the AirTAC SU32X15 is discontinued and end-of-life. The direct replacement is the SAU32X15. It shares the same 32 mm bore, 15 mm stroke, 402 N push force at 0.5 MPa, 1/8" port, and SC-series mounting accessories, so it fits the same application directly.
This double-acting cylinder provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. It cannot hold a load on air loss—the adjustable 21 mm air cushion only decelerates near stroke end. For vertical holding, use an external rod lock or pilot-operated check valve.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X15 replacement — usually within 7-8 hours.
