This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the drop-in replacement SAUJ32X80-75S, 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 SUJ32X80-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X80-75S 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 SAUJ32X80-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X80-75S
The AirTAC SUJ32X80-75S is a 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. At 0.5 MPa it delivers 402 N push and 345 N pull force through a 1/8" port, operating at 30-800 mm/s. This bore features a 12 mm rod, M10x1.25 rod thread, and 21 mm adjustable air cushions.
This SUJ model is discontinued; the exact drop-in replacement is the SAUJ32X80-75S, matching the 32 mm bore, 80 mm stroke, force, and FA/LB mounting. For your computed buyer insight, expect a safe working load around 241 N (60% of the 0.5 MPa push) or a 20 kg vertical lift with a 2:1 margin. The stop screw sets end position but is not a load lock; use an external rod lock for held loads. The -S magnet pairs with legacy CS1-B/DS1-B switches, while the SAUJ upgrades to CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X80-75S 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 SAUJ32X80-75S 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 SUJ32X80-75S Is Used
Variable Pitch Indexing
Dial in exact extend distances on packaging lines by trimming the stroke up to 75 mm on-site to accommodate different product widths without swapping cylinders.
Adjustable Diverter Arms
Set precise sorting positions on a conveyor by tuning the extend stop screw, allowing rapid reconfiguration for changing package sizes.
Custom Depth Pushers
Regulate how far a product is pushed into a variable-depth container by field-adjusting the extend stroke down to a 5 mm minimum.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X80-75S with the SAUJ32X80-75S
To replace the discontinued SUJ32X80-75S, order the drop-in SAUJ32X80-75S, which preserves the 32 mm bore, 80 mm nominal stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting. When sizing both ways, the neighbouring 40 mm bore provides 628 N push at 0.5 MPa if you need more force, while the 32 mm bore itself offers 402 N push. Choose the 75 mm adjust window when you need extreme field flexibility to trim the extend stroke down to a 5 mm minimum. Retain your SC-series mounting accessories, but note the sensor change: the -S magnet used legacy CS1-B/DS1-B switches on the SUJ, whereas the SAUJ requires current CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify your side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X80-75S
- ✓ 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 SUJ32X80-75S FAQ
Yes, the AirTAC SUJ32X80-75S is discontinued. The exact drop-in replacement is the SAUJ32X80-75S, which matches the 32 mm bore, 80 mm stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting. You will need to upgrade your position sensing, as the SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
It provides 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 theoretical max of 82 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 75 mm on-site, giving a usable extend range of 5-80 mm. The stop sets end position and is not a load lock.
