This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X500-20S, 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 SUJ Adjustable Cylinder SUJ32X500-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X500-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 500mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X500-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X500-20S
The AirTAC SUJ32X500-20S is a double-acting double-rod profile cylinder with an adjustable stroke, letting you trim the extend stroke by up to 20 mm on-site. This yields a usable extend range of 480-500 mm from the 500 mm nominal maximum. This discontinued model is fully replaced by the direct replacement SAUJ32X500-20S, which retains the exact bore, stroke, force, port, and SC-series FA/LB mounting.
The external stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for holding. Because the 500 mm stroke is long, external guides are recommended to prevent rod bending. The SAUJ upgrade switches from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X500-20S 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 SAUJ32X500-20S 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 SUJ Adjustable Cylinder SUJ32X500-20S Is Used
Variable Pitch Pushing
Tuning the extend stroke by up to 20 mm on-site to push parts of varying widths into a machining station without swapping the entire cylinder.
Adjustable Diverting
Field-adjusting the 500 mm extend stop to precisely meet shifting conveyor lane widths or product sizes on the fly.
End-Stop Calibration
Fine-tuning the end-of-stroke position within the 480-500 mm window to calibrate stops after mechanical wear or tooling changes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X500-20S with the SAUJ32X500-20S
To replace the discontinued SUJ32X500-20S, use the exact direct replacement SAUJ32X500-20S, which matches the 32 mm bore, 500 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 20 mm adjust window if you need 480-500 mm of extend travel tuned on-site. For the -S magnet option, the SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Because the 500 mm stroke is long, use external guides to manage side-load and prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X500-20S
- ✓ 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 SUJ Adjustable Cylinder SUJ32X500-20S FAQ
Yes, the SUJ32X500-20S is discontinued. The direct replacement is the AirTAC SAUJ32X500-20S, which matches the 32 mm bore, 500 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 20 mm, allowing you to shorten the 500 mm extend stroke down to 480 mm on-site. The stop sets end position and is not a load lock.
