This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X100-30S, 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 SUJ50X100-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X100-30S is a double-acting profile-type standard cylinder with a Ø50mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X100-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X100-30S
The AirTAC SUJ50X100-30S is a double-acting double-rod profile cylinder with a 50mm bore and 100mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 70-100mm window. The extruded aluminum profile barrel is more compact than a standard cylinder of the same bore.
This SUJ50X100-30S unit is discontinued; the direct replacement is the SAUJ50X100-30S, retaining the same force, 1/4" port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B switches. 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 SAUJ50X100-30S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUJ50X100-30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ50X100-30S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×100 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ50X100-30S Is Used
Variable Depth Diving Heads
Allows operators to tune the extend stroke on-site for material thickness variations without swapping cylinders.
Adjustable Transfer Pushers
Accommodates changing package sizes on a line by trimming the extend stroke to hit exact push distances.
Dynamic Sorting Diverters
Provides field stroke tuning to alter the divert path length for mixed product runs on the fly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X100-30S with the SAUJ50X100-30S
To replace the discontinued SUJ50X100-30S, order the direct replacement SAUJ50X100-30S, which matches the 50mm bore, 100mm nominal stroke, 30mm adjust window, and FA/LB mounting. Choose the 30mm adjust window if you need on-site extend trimming between 70-100mm. Because this is an -S model, you must upgrade your position sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For strokes of 300mm or longer, verify your side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X100-30S
- ✓ 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 SUJ50X100-30S FAQ
Yes, the SUJ50X100-30S is discontinued. The direct replacement is the SAUJ50X100-30S, which matches the 50mm bore, 100mm stroke, 30mm adjust window, 1/4" port, and FA/LB mounting. You will need to upgrade your sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The external stop screw lets you trim the extend stroke by up to 30mm on-site, giving a usable 70-100mm window. The stop sets end position but is not a load lock.
