This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ80X50-10S, 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 SUJ80X50-10S
The AirTAC SUJ Adjustable Cylinder SUJ80X50-10S is a double-acting profile-type standard cylinder with a Ø80mm bore and 50mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ80X50-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ80X50-10S
The AirTAC SUJ80X50-10S is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, giving a usable 40-50 mm extension out of the 50 mm nominal maximum. It features a 3/8" port, an M20x1.5 rod thread, and 28 mm adjustable air cushions at each end.
This unit is discontinued; the direct replacement is the SAUJ80X50-10S, which retains the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade shifts legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. Note that the external stop 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 SAUJ80X50-10S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAUJ80X50-10S 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 SUJ80X50-10S Is Used
Dialing in Clamping Depth
Adjusting the extend stop on-site by up to 10 mm allows operators to fine-tune clamping contact without swapping cylinders when material thicknesses vary slightly.
Sorting Diverter Positioning
Trimming the 50 mm extend stroke lets a diverter arm hit exact lane angles on a conveyor, accommodating package size changes on the fly.
Packaging Pusher Travel
A 10 mm stroke reduction window provides the exact push distance needed to index cartons into a case packer without overtravel.
Replacing the Airtac SUJ Adjustable Cylinder SUJ80X50-10S with the SAUJ80X50-10S
To replace the discontinued SUJ80X50-10S, specify the direct replacement SAUJ80X50-10S, which matches the 80 mm bore, 50 mm nominal stroke, 10 mm adjust window, 3/8" port, and FA/LB mounting. Choose the 10 mm adjust window when you need precise 40-50 mm extend tuning that beats adding an external stop to a fixed SAU cylinder. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. For strokes at or above 300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ80X50-10S
- ✓ 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 SUJ80X50-10S FAQ
Yes, the SUJ80X50-10S is discontinued. The direct replacement is the SAUJ80X50-10S, which shares the same 80 mm bore, 50 mm stroke, 10 mm adjust window, 3/8" port, and FA/LB mounting. You will need to upgrade the piston magnet sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG series.
The external stop screw provides a 10 mm adjustment window, allowing you to shorten the 50 mm nominal extend stroke down to 40 mm on-site. This stop sets the end position and is not a load lock.
