This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X450-30, 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 SUJ32X450-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X450-30 is a double-acting profile-type standard cylinder with a Ø32mm bore and 450mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X450-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X450-30
The AirTAC SUJ32X450-30 is a double-acting double-rod profile cylinder with a 32 mm bore and 450 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable 420-450 mm end position. This SKU has no magnet and cannot take a switch. The stop sets the end position but is not a load lock; use an external rod lock for held loads.
This SUJ model is discontinued; the direct replacement is the SAUJ32X450-30, keeping the same bore, stroke, force, port and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. With a 450 mm stroke, add external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X450-30 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 SAUJ32X450-30 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 SUJ32X450-30 Is Used
Variable Stroke Clamping
Adjusts the extend end position on-site by up to 30 mm to clamp parts of varying heights without re-engineering the entire fixture setup.
Adjustable Diverter Gate
Tunes the extend stroke in the field to deflect different package sizes on a line, ensuring precise routing without swapping cylinders.
Variable Depth Ejector
Trims the extend stroke by up to 30 mm to push boxes varying distances onto accumulating rollers, adapting to changing pack depths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X450-30 with the SAUJ32X450-30
To replace the discontinued SUJ32X450-30, order the direct replacement SAUJ32X450-30, which matches the 32 mm bore, 450 mm stroke, 30 mm adjust window, 1/8" port and FA/LB mounting. Choose the 30 mm adjust window if you need field tuning of the extend stroke. Because this non-magnetic SKU cannot take a switch, the SAUJ upgrade lets you use current CMSG/DMSG/EMSG sensors if you add the -S option. At 450 mm stroke, use external guides to manage side-load and rod-bending.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X450-30
- ✓ 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 SUJ32X450-30 FAQ
Yes, the SUJ32X450-30 is discontinued. The direct replacement is the SAUJ32X450-30, which shares the same 32 mm bore, 450 mm stroke, 30 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 switches.
The external stop screw provides a 30 mm adjust window, allowing you to shorten the 450 mm extend stroke down to 420 mm on-site. The stop sets end position only; it is not a load lock.
