This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X75, 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 SU32X75 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 SAU32X75, which matches its bore, stroke, force and mounting.
The AirTAC SU32X75 is a discontinued double-acting profile-type cylinder with a 32 mm bore and 75 mm stroke. It delivers 402 N push force at 0.5 MPa through a 1/8" port. AirTAC replaced this unit with the SAU32X75, a direct upgrade sharing the exact same body dimensions, stroke, output force, and SC-series mounting accessories.
This compact extruded-aluminium barrel is shorter than a standard ISO 15552 cylinder of the same bore. Because this specific SKU lacks a magnet, it cannot accept a position sensor. The SAU32X75 successor also introduces a SAUF variant with a built-in 4M solenoid valve the original SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X75 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 SAU32X75 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.
Actuates a short 75 mm stroke diverter arm to route small boxes on a packing line without occupying much space.
Provides the 402 N push force at 0.5 MPa needed to open and close compact pneumatic grippers handling 20 kg vertical loads.
To replace the discontinued SU32X75, order the SAU32X75 direct equivalent, matching the 32 mm bore, 75 mm stroke, M10x1.25 rod thread, and 1/8" port. Confirm your thread standard (PT, G, or NPT) and SC-series mounting bracket (LB, FA, FB, CA, CB, or TC). Since this SKU has no -S magnet, it cannot support sensing; if you need switches on the SAU replacement, add the -S option and note that sensors upgrade from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG. If your application needs load holding on air loss, add an external rod lock or pilot-operated check valve, as the 21 mm adjustable cushions only decelerate. For higher force needs, step up to the 40 mm bore (628 N push at 0.5 MPa); for lighter duties, the SAU32X75 is ideal. The SAUF built-in-valve option is available if you want to simplify piping.
Replacement checklist
Yes, the SU32X75 is discontinued. The direct replacement is the AirTAC SAU32X75. It shares the identical 32 mm bore, 75 mm stroke, 402 N force at 0.5 MPa, 1/8" port, and SC-series mounting, so it drops straight into the same application.
At 0.5 MPa it pushes 402 N and pulls 345 N. Push force is 563 N at 0.7 MPa, 724 N at 0.9 MPa, with a theoretical max of 82 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot take a sensor. If you order the SAU32X75-S replacement, the sensor family changes from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X75 replacement — usually within 7-8 hours.
