This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X300-50, 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 SUJ32X300-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X300-50 is a double-acting profile-type standard cylinder with a Ø32mm bore and 300mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X300-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X300-50
The AirTAC SUJ32X300-50 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 250-300 mm extension out of the 300 mm nominal maximum. The 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 held loads.
Because this SKU lacks a magnet, it cannot take a magnetic switch. The direct replacement is the SAUJ32X300-50, which matches the 32 mm bore, 300 mm stroke, force, port, and FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches and offers the SAUF built-in-valve variant the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X300-50 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 SAUJ32X300-50 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 SUJ32X300-50 Is Used
Variable-Length Ejector
Tuning the extend stroke by up to 50 mm on-site allows an ejection pin to hit varying material lengths without swapping the entire cylinder.
Adjustable Forming Stop
The 50 mm adjust window lets operators set precise end positions for pressing or forming tasks that require incremental depth changes across different batches.
Customizable Diverter Arm
Trimming the extend stroke on the fly adapts a conveyor diverter arm to different package widths, ensuring accurate routing without mechanical rebuilds.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X300-50 with the SAUJ32X300-50
To replace the discontinued SUJ32X300-50, specify the SAUJ32X300-50 direct: it preserves the 32 mm bore, 300 mm nominal stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 50 mm adjust window if you need on-site tuning of the extend stroke between 250 and 300 mm. For stroke lengths of 300 mm or more, account for side-load and rod-bending forces by adding external guides to prevent premature seal wear. This non-magnetic SKU cannot accept sensors; if position detection is required, migrate to the SAUJ and use current CMSG/DMSG/EMSG switches. The external stop screw sets the end position but does not lock the load—maintain live air or use an external rod lock for holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X300-50
- ✓ 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
