This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X120, 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 SU32X120 is a double-acting profile-type standard cylinder with a Ø32mm bore and 120mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X120, which matches its bore, stroke, force and mounting.
The AirTAC SU32X120 is a discontinued double-acting profile-type cylinder with a 32mm bore and 120mm stroke. Delivering 402 N push at 0.5 MPa, it is superseded by the SAU32X120 direct replacement, retaining the exact 1/8" port, M10x1.25 rod thread and SC-series mounting footprint.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent. Note this non-magnetic SKU cannot take a sensor; the SAU upgrade uses CMSG/DMSG/EMSG switches and adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X120 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 SAU32X120 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×120 | 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 kick lightweight machined components out of a fixture on an automated lathe.
Actuates a short 120mm stroke routing gate to deflect small cartons on a packaging line without occupying excessive frame space.
To replace this discontinued SU32X120, order the SAU32X120. Confirm the 1/8" port (PT/G/NPT) and your SC-series mounting (LB/FA/FB/CA/CB). As this SKU lacks a magnet, no sensor can be fitted. Sizing both ways: a 40mm bore yields 628 N push at 0.5 MPa, while a 20mm bore offers 252 N. For the 120mm stroke, ensure adequate guide support to prevent rod bending. A plain cylinder drifts on air loss; for load holding use an external rod lock or pilot-operated check valve, as cushions only decelerate.
Replacement checklist
Yes, the AirTAC SU32X120 is discontinued. The direct replacement is the SAU32X120, offering identical 32mm bore, 120mm stroke, output force, 1/8" port and SC-series mounting compatibility.
It delivers 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. This specific SKU has no magnet, so it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X120 replacement — usually within 7-8 hours.
