This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X75S, 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 SU32X75S is a double-acting profile-type standard cylinder with a Ø32mm bore and 75mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X75S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X75S is a discontinued double-acting profile-type cylinder with a 32 mm bore and 75 mm stroke, delivering 402 N push force at 0.5 MPa. AirTAC replaced this unit with the SAU32X75S, a direct alternative retaining the exact bore, stroke, output, 1/8" port and SC-series mounting footprint.
This compact extruded-aluminium body is shorter than an ISO 15552 cylinder of the same size. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades this to CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X75S 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 SAU32X75S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×75 | 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 knock lightweight moulded parts from a fixture.
Executes 75 mm strokes to push small cartons between adjacent conveyor lanes.
Actuates routing gates in distribution hubs where a compact 32 mm body profile is required.
To replace the SU32X75S, order the SAU32X75S, confirming the 1/8" port, M10x1.25 rod thread and SC-series mounting (LB/FA/FB/CA/CB) are retained. Because this unit has the -S magnet, note that your legacy CS1-B/DS1-B switches must change to the current CMSG/DMSG/EMSG family on the SAU. If your application needs higher force, the neighbouring 40 mm bore provides 628 N push at 0.5 MPa. For intermediate stopping rather than end-of-stroke deceleration, the 21 mm adjustable cushion is not a brake; add an external rod lock or pilot-operated check valve, as the cylinder drifts without live air. The SAU line also adds a SAUF variant with a built-in 4M solenoid valve the SU lacked.
Replacement checklist
Yes, the SU32X75S is end-of-life. The direct replacement is the AirTAC SAU32X75S. It matches the 32 mm bore, 75 mm stroke, 402 N force, 1/8" port and SC-series mounting. The only change is that the -S magnet now uses CMSG/DMSG/EMSG switches instead of the older CS1-B/DS1-B sensors.
The 32 mm bore features a 1/8" port and M10x1.25 rod thread. It delivers 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 maximum of 82 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X75S replacement — usually within 7-8 hours.
