This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X50-20, 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 SUJ32X50-20
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X50-20 is a double-acting profile-type standard cylinder with a Ø32mm bore and 50mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X50-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X50-20
The AirTAC SUJ32X50-20 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 (usable range 30-50 mm). The external stop screw sets the end position but is not a load lock.
This SUJ model is discontinued; the direct replacement is the SAUJ32X50-20, matching the bore, stroke, force, and port. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. As a non-magnet SKU, it cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X50-20 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 SAUJ32X50-20 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 SUJ32X50-20 Is Used
Variable Pitch Indexing
Adjusts the extend stroke on-site to tune the pitch of parts feeding into a light assembly fixture without swapping cylinders.
Variable Diverter Gate
Sets the reach of a sorting gate arm by trimming the extend position to accommodate different carton widths on the fly.
Adjustable Pusher Stop
Regulates the push distance of a manual pallet loading assist to handle varying product depths accurately.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X50-20 with the SAUJ32X50-20
To replace the discontinued SUJ32X50-20, order the direct replacement SAUJ32X50-20, which retains the 1/8" port, 50 mm stroke, 20 mm adjust window, and FA/LB mounting. Choose the 20 mm adjust window if you need field tuning of the extend stroke; for fixed positions, a standard SAU cylinder suffices. Because this is a non-magnet SKU, it cannot accept sensors; upgrading to the SAUJ with a -S suffix enables CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X50-20
- ✓ 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 SUJ32X50-20 FAQ
Yes, the SUJ32X50-20 is discontinued. The direct replacement is the SAUJ32X50-20, offering the same 32 mm bore, 50 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw lets you trim the extend stroke by up to 20 mm on-site, giving a usable extend range of 30-50 mm. The stop sets end position only; it is not a load lock.
