This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X100-10, 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 SUJ50X100-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X100-10 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 SAUJ50X100-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X100-10
The AirTAC SUJ50X100-10 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, yielding a usable 90-100 mm extension out of the 100 mm nominal maximum. This discontinued adjustable-stroke unit features a 50 mm bore, a 20 mm rod, adjustable 21 mm cushions, and a 1/4" port.
The direct replacement is the SAUJ50X100-10, matching the bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors, as this legacy model used CS1-B/DS1-B switches (this specific non-magnet SKU cannot take a sensor anyway). Note the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X100-10 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 SAUJ50X100-10 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SUJ50X100-10 Is Used
Dialing in Clamp Position
Trimming the extend stroke by up to 10 mm on-site to set an exact clamping depth without machining custom spacers.
Sorting Diverter Timing
Fine-tuning the extend end position of a diverting gate to accommodate slight product size variations on the line.
Packaging Stop Alignment
Adjusting the extend stroke outward to precisely meet a moving web or packaging material for consistent registration.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X100-10 with the SAUJ50X100-10
To replace the discontinued SUJ50X100-10, order the direct replacement SAUJ50X100-10, which preserves the 50 mm bore, 100 mm nominal stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 10 mm adjust window when you need minor field-tuning of the extend end position; for larger trims, select a bigger adjust suffix. Because this non-magnet SKU lacks a piston magnet, it cannot accept a sensor; if sensing is required, move to an -S SAUJ model using CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. The stop screw is an end-position stop, not a lock; a plain cylinder drifts on air loss, so add an external rod lock or pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X100-10
- ✓ 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 SUJ50X100-10 FAQ
Yes, the SUJ50X100-10 is discontinued. The direct replacement is the SAUJ50X100-10, which matches the 50 mm bore, 100 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors, whereas this legacy SUJ used CS1-B/DS1-B switches.
The external stop screw window is 10 mm, shortening the extend stroke from the 100 mm nominal maximum down to 90 mm. The stop sets end position and is not a load lock.
