This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X125-30, 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 SUJ100X125-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X125-30 is a double-acting profile-type standard cylinder with a Ø100mm bore and 125mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X125-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X125-30
The AirTAC SUJ100X125-30 is a discontinued double-acting double-rod adjustable-stroke profile cylinder. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 95-125mm extend window from the 125mm nominal maximum. It features a 1/2" port, M20x1.5 rod thread, and 29mm adjustable cushions.
This unit is replaced direct by the SAUJ100X125-30, matching the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy SUJ used CS1-B/DS1-B switches. Note this specific SKU lacks a magnet and cannot take a switch. 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 SAUJ100X125-30 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X125-30 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 SUJ100X125-30 Is Used
Variable Depth Forming
Adjusting the end position on-site by up to 30mm allows a press to tune material forming depth without machining new spacers.
Adjustable Diverter Stroke
Tuning the extend stroke between 95mm and 125mm accommodates changing package widths on a sorting line.
Variable Height Stops
Field-trimming the extend stroke sets precise mechanical stop positions for varying pallet heights in a compact profile body.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X125-30 with the SAUJ100X125-30
To replace the discontinued SUJ100X125-30, specify the direct replacement SAUJ100X125-30, which preserves the 100mm bore, 125mm stroke, 1/2" port, and FA/LB mounting. Choose the 30mm adjust window if your mechanism requires field-tuning the extend stroke between 95mm and 125mm. Because this non-magnetic SKU cannot accept sensors, if position detection is needed on the SAUJ, order the -S variant and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300mm or longer, verify side-load limits to prevent guide wear. Remember the stop screw only sets end position; it does not lock the load on air loss, so add an external rod lock for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X125-30
- ✓ 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 SUJ100X125-30 FAQ
Yes, the SUJ100X125-30 is discontinued. The direct replacement is the SAUJ100X125-30, which matches the 100mm bore, 125mm stroke, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 30mm, allowing you to shorten the 125mm nominal extend stroke down to 95mm on-site. The stop sets end position but is not a load lock.
