This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X20, 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.
Airtac SU32~50 Standard Cylinder SU32X20
The AirTAC Airtac SU32~50 Standard Cylinder SU32X20 is a double-acting profile-type standard cylinder with a Ø32mm bore and 20mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X20, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X20
The AirTAC SU32X20 is a discontinued double-acting profile-type cylinder with a 32mm bore and 20mm stroke. It delivers 402N push and 345N pull at 0.5MPa through a 1/8 port. The direct replacement is the SAU32X20, matching the body, force, and SC-series mounts.
This compact extruded-aluminium body is shorter than same-bore ISO 15552 units. This non-magnet SKU cannot take a sensor, whereas the SAU upgrade supports CMSG/DMSG/EMSG switches and a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X20 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X20 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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.
Where the Airtac SU32~50 Standard Cylinder SU32X20 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to eject light machined components from a fixture without damaging the surface.
Package Diverting
Short 20mm stroke actuates a diverter arm on a packaging line, fitting neatly into tight machinery clearances.
Replacing the Airtac SU32~50 Standard Cylinder SU32X20 with the SAU32X20
To replace this discontinued SU32X20, order the SAU32X20 direct equivalent, verifying the 20mm stroke, 1/8 port, M10x1.25 rod thread, and SC-series mounting. If downsizing from a 40mm bore, note the 40mm offers 628N push at 0.5MPa; if upsizing from 32mm, the 40mm provides extra force margin. Because this is a non-magnet SKU, it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches if sensing is added. For any held load, add an external rod lock or pilot-operated check valve, as the cushion only decelerates. The SAUF variant adds a built-in valve the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU32X20
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU32~50 Standard Cylinder SU32X20 FAQ
Yes, the AirTAC SU32X20 is discontinued. The direct replacement is the SAU32X20. It shares the same 32mm bore, 20mm stroke, 402N force, 1/8 port, and SC-series mounting, so it fits the same application directly.
It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. This specific SKU lacks a magnet and cannot take a sensor; the SAU32X20 replacement uses CMSG/DMSG/EMSG switches if sensing is required.
