This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the drop-in replacement SAUJ32X80-75, 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 SUJ32X80-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X80-75 is a double-acting profile-type standard cylinder with a Ø32mm bore and 80mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X80-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X80-75
The AirTAC SUJ32X80-75 is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 5-80 mm stroke from the 80 mm nominal maximum. The 32 mm bore uses a 1/8" port and delivers 402 N push and 345 N pull at 0.5 MPa. This compact extruded barrel is shorter than an ISO 15552 cylinder of the same bore.
The exact drop-in replacement is the SAUJ32X80-75, which retains the bore, stroke, force, port, and FA/LB mounting. A computed buyer insight: the safe working load is roughly 241 N (60% of the 402 N push force), allowing a vertical lift of about 20 kg with a 2:1 margin. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. This non-magnet SKU cannot take a switch, and the SAUJ upgrades to CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X80-75 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 SAUJ32X80-75 produces the same force from the same bore — a true drop-in on output. 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 SUJ32X80-75 Is Used
Variable Pitch Feed
Adjusting the extend stroke on-site by up to 75 mm to tune part ejection distance without swapping cylinders.
Sorting Diverter
Setting a precise 40 mm extend stroke to deflect varying package sizes on a 1/8" ported compact assembly.
Adjustable Stop Gate
Trimming the extend stroke down to 20 mm to create a temporary physical stop for different pallet widths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X80-75 with the SAUJ32X80-75
To replace the discontinued SUJ32X80-75, order the SAUJ32X80-75 drop-in, keeping the 32 mm bore, 80 mm nominal stroke, 75 mm adjust window, and 1/8" port. When sizing both ways, the neighbouring 40 mm bore offers higher force (628 N push at 0.5 MPa), while dropping pressure to 0.5 MPa on this 32 mm bore yields 402 N push. Choose the 75 mm adjust window when you need on-site extend tuning from 5 to 80 mm, which often beats installing a fixed SAU plus an external stop. Mounting is via Basic, FA, or LB (SC-series compatible). Because this SKU lacks a magnet, it cannot take a sensor; the SAUJ uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify your side-load limits. The stop screw sets end position only and does not hold loads on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X80-75
- ✓ 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 SUJ32X80-75 FAQ
Yes, the SUJ32X80-75 is discontinued. The exact drop-in replacement is the SAUJ32X80-75, which matches the 32 mm bore, 80 mm stroke, 75 mm adjust window, and 1/8" port.
The 32 mm bore delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a max of 82 kgf at 1.0 MPa. The external stop screw trims the extend stroke by up to 75 mm on-site, giving a usable 5-80 mm stroke. The stop sets end position and is not a load lock.
