This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the drop-in replacement SAUJ32X80-50S, 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 SUJ32X80-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X80-50S 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 SAUJ32X80-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X80-50S
The AirTAC SUJ32X80-50S is a double-acting, single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site. With a nominal 80 mm stroke, the usable extend range is 30-80 mm. This bore delivers 402 N push and 345 N pull at 0.5 MPa, features a 1/8" port, and uses adjustable 21 mm cushions. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
This SUJ model is discontinued and the exact drop-in replacement is the SAUJ32X80-50S, which shares the same profile body, 32 mm bore, 80 mm stroke, force, and FA/LB mounting. For your sizing, a safe working load is roughly 241 N (60% of the 0.5 MPa push), equating to a 20 kg vertical lift with a 2:1 margin. The SAUJ upgrade transitions from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X80-50S 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 SAUJ32X80-50S 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 SUJ32X80-50S Is Used
Probe Contact Adjustment
Testing stations needing precise probe touch points can dial in the extend stroke from 30 to 80 mm on-site, ensuring exact contact pressure without machining custom spacers.
Variable Length Diverters
Package diverters handling mixed box sizes use the 50 mm trim window to instantly reposition the pusher stroke, adapting to different carton depths on the fly.
Adjustable End Stops
Assembly lines use the external stop screw to set precise part ejection points, allowing operators to fine-tune the 80 mm maximum stroke for varying product widths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X80-50S with the SAUJ32X80-50S
To replace the discontinued SUJ32X80-50S, order the drop-in SAUJ32X80-50S, retaining the 32 mm bore, 80 mm nominal stroke, 1/8" port, and FA/LB mounts. If you need more force, the neighbouring 40 mm bore provides 628 N push at 0.5 MPa; if less force is acceptable, there is no smaller standard SUJ bore. The 50 mm adjust window lets you set the extend stroke anywhere from 30 to 80 mm on-site, which is often cheaper and more compact than fitting a fixed SAU cylinder plus an external stop. Because this is an -S model, you must swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X80-50S
- ✓ 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 SUJ32X80-50S FAQ
Yes, the AirTAC SUJ32X80-50S is discontinued. The exact drop-in replacement is the SAUJ32X80-50S, which matches the 32 mm bore, 80 mm stroke, 1/8" port, and FA/LB mounting. You will need to upgrade your position sensing from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG series.
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 theoretical max of 82 kgf at 1.0 MPa. The external stop screw provides a 50 mm adjustment window, allowing you to shorten the 80 mm nominal extend stroke down to 30 mm on-site. The stop sets end position only and does not lock the load.
