This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X150-30, 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 SUJ50X150-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X150-30 is a double-acting profile-type standard cylinder with a Ø50mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X150-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X150-30
The AirTAC SUJ50X150-30 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, giving a usable extend range of 120-150 mm from the 150 mm nominal maximum. The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads.
Because this SUJ model is discontinued, the direct replacement is the SAUJ50X150-30, retaining the same bore, stroke, force, 1/4" port, and SC-series FA/LB mounting. The SAUJ upgrade moves to current CMSG/DMSG/EMSG sensors, leaving behind the legacy CS1-B/DS1-B switches this SKU used. Note this non-magnetic variant cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X150-30 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 SAUJ50X150-30 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 SUJ50X150-30 Is Used
Custom Clamp Positioning
Trimming the extend stroke by up to 30 mm on-site allows a clamping actuator to hit varying material thicknesses without swapping cylinders or machining spacers.
Variable Length Diverter
An external stop screw lets operators dial in the exact push distance for diverting different package sizes on a line, setting the end position precisely where needed.
Adjustable Sealing Head
Dialing the extend stroke down from 150 mm to 120 mm accommodates varying pouch depths in packaging machinery, ensuring consistent sealing pressure without reprogramming.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X150-30 with the SAUJ50X150-30
To replace the discontinued SUJ50X150-30, order the SAUJ50X150-30 direct: it preserves the 150 mm stroke, 30 mm adjust window, 1/4" port, and FA/LB mounts. Choose the 30 mm adjust window when you need precise end-position tuning without machining spacers. This non-magnetic SKU cannot accept a sensor; if you need position feedback on the SAUJ, specify the -S option for CMSG/DMSG/EMSG sensor compatibility. For strokes of 300 mm or longer, verify your side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X150-30
- ✓ 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 SUJ50X150-30 FAQ
Yes, the SUJ50X150-30 is discontinued. The direct replacement is the SAUJ50X150-30, which shares the same 50 mm bore, 150 mm stroke, 30 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw allows you to shorten the 150 mm nominal extend stroke by up to 30 mm on-site (usable range 120-150 mm). The stop sets end position only; it is not a load lock.
