This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X80-20, 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 SUJ32X80-20
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X80-20 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 direct replacement is the SAUJ32X80-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X80-20
The AirTAC SUJ32X80-20 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 60 to 80 mm extension from the 80 mm nominal maximum.
Because the SUJ line is end-of-life, the direct replacement is the SAUJ32X80-20, which retains the same bore, 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 used here. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X80-20 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 SAUJ32X80-20 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 SUJ32X80-20 Is Used
Variable Pitch Feed
Dialing in the extend stroke by up to 20 mm on-site allows a 32 mm bore actuator to push parts into a lathe chuck at varying depths without swapping the entire cylinder.
Adjustable Transfer Stop
A profile cylinder acting as a conveyor gate can be fine-tuned externally to accommodate different product lengths on the fly, ensuring precise positioning.
Variable Depth Sealing
Trimming the extend stroke externally lets a packaging line adapt the pressing depth for different carton sizes using the same 80 mm nominal stroke actuator.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X80-20 with the SAUJ32X80-20
To replace the discontinued SUJ32X80-20, specify the SAUJ32X80-20 direct, keeping the 32 mm bore, 80 mm stroke, 1/8" port, and FA/LB mounting. Choose the 20 mm adjust window if you need field tuning of the extend stroke; for fixed positions, a standard SAU cylinder is simpler. This non-magnet SKU cannot take a switch, but the SAUJ supports CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X80-20
- ✓ 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 SUJ32X80-20 FAQ
Yes, the SUJ32X80-20 is discontinued. The direct replacement is the SAUJ32X80-20, which matches the 32 mm bore, 80 mm stroke, 1/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw offers a 20 mm adjust window, allowing the 80 mm extend stroke to be shortened to 60 mm on-site. The stop sets end position and is not a load lock.
