This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X150-10S, 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 SUJ50X150-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X150-10S 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 SAUJ50X150-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X150-10S
The AirTAC SUJ50X150-10S is a double-acting double-rod profile cylinder with a 150 mm nominal stroke and an external stop screw that lets you trim the extend stroke by up to 10 mm on-site (yielding a 140-150 mm usable window). Because the stop screw merely sets the end position, it is not a load lock; you must add an external rod lock or pilot-operated check valve if you need to hold a load safely on air loss. The 50 mm bore uses a 1/4" port, a Ø20 mm rod, and adjustable cushions.
This discontinued model is replaced direct by the SAUJ50X150-10S, which shares the exact bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade moves to current CMSG/DMSG/EMSG sensors (this SUJ used legacy CS1-B/DS1-B switches) and offers the SAUF built-in-valve variant the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X150-10S 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 SAUJ50X150-10S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×150 | 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 SUJ50X150-10S Is Used
Component Sealing Presses
Dialing in the exact crush distance on delicate gaskets or seals by trimming the extend stroke up to 10 mm on-site without machining hard stops.
Flight Transfer Diverters
Adjusting the extend reach to accommodate slight profile changes between different product sizes running on the same packaging line.
Pallet Stop Positioning
Fine-tuning the stopping point of pallets on a roller conveyor by tweaking the rod extension rather than moving the entire cylinder mount.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X150-10S with the SAUJ50X150-10S
To replace the SUJ50X150-10S, order the SAUJ50X150-10S; it is a direct swap retaining the 50 mm bore, 150 mm stroke, 1/4" port, and FA/LB mounting. Choose the 10 mm adjust window when you only need minor field tuning of the extend position rather than a large stroke reduction. Because this unit has the -S magnet, you must migrate from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300 mm or longer, verify your side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X150-10S
- ✓ 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 SUJ50X150-10S FAQ
Yes, the AirTAC SUJ50X150-10S is discontinued. The direct replacement is the SAUJ50X150-10S, which matches the 50 mm bore, 150 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. You will need to upgrade your switches from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG sensors.
The external stop screw provides a 10 mm adjust window, meaning the 150 mm nominal extend stroke can be shortened to a 140 mm minimum on-site. The stop sets end position only and does not lock the load.
