This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X450-75S, 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 SUJ32X450-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X450-75S 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 SAUJ32X450-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X450-75S
The AirTAC SUJ32X450-75S is a double-acting double-rod adjustable-stroke profile cylinder. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, giving a usable 375-450 mm window from the 450 mm nominal maximum. This SUJ model is discontinued; the direct replacement is the SAUJ32X450-75S, retaining the same body, force, and FA/LB mounting.
The stop screw sets the end position but is not a load lock; drift occurs on air loss, requiring an external rod lock for held loads. The SAUJ upgrade switches legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. Because stroke is 450 mm, use external guides to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X450-75S 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 SAUJ32X450-75S 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 SUJ32X450-75S Is Used
Variable Pitch Pushing
Tuning the extend stroke on-site by up to 75 mm to push parts of varying widths into a press without swapping entire actuators.
Adjustable Diverter Arms
Setting precise reach distances on a conveyor line to deflect different package sizes accurately at varying downstream lanes.
Format Change Tucking
Adjusting the extend endpoint on the fly to tuck carton flaps of differing depths during rapid packaging format changes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X450-75S with the SAUJ32X450-75S
To replace the discontinued SUJ32X450-75S, order the direct replacement SAUJ32X450-75S. It preserves the 32 mm bore, 450 mm stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting. If resizing, neighbouring bores change the 0.5 MPa push force: a 40 mm bore gives 628 N, while smaller bores offer less. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S model. For the 450 mm stroke, add external guides to manage side-load and rod-bending risks. The stop screw trims the extend stroke by up to 75 mm on-site but does not lock the load.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X450-75S
- ✓ 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 SUJ32X450-75S FAQ
Yes, the SUJ32X450-75S is discontinued. The direct replacement is the SAUJ32X450-75S. It matches the 32 mm bore, 450 mm stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ upgrades the sensor track to current CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B.
The external stop screw trims the extend stroke by up to 75 mm on-site, giving a usable 375-450 mm window from the 450 mm maximum. The stop sets end position and is not a load lock.
