This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X150-100S, 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 SUJ50X150-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X150-100S 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 SAUJ50X150-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X150-100S
The AirTAC SUJ50X150-100S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 50-150 mm extend window from the 150 mm nominal maximum. It features a 1/4" port, an M16x1.5 rod thread, and 21 mm adjustable cushions. This unit is discontinued; the direct replacement is the SAUJ50X150-100S, retaining the same force, port, and FA/LB mounting.
The stop screw sets end position but is not a load lock; drift occurs on air loss, so use an external rod lock for held loads. Upgrading to the SAUJ brings current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here, and offers the SAUF built-in-valve variant. The compact profile barrel is shorter than standard cylinders of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X150-100S 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 SAUJ50X150-100S 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 SUJ50X150-100S Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning from 50 to 150 mm to accommodate changing material lengths or pitch spacing without swapping the cylinder.
Adjustable Diverter Gate
Enables field adjustment of the push-out distance for diverting different package sizes on a packaging line.
Variable Depth Pusher
Provides a configurable 100 mm stroke trim to push varied carton depths into storage racks from a single actuator.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X150-100S with the SAUJ50X150-100S
To replace this discontinued model, specify the SAUJ50X150-100S, which matches the 50 mm bore, 150 mm nominal stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 100 mm adjust window when you need wide on-site extend tuning from 50 to 150 mm; a smaller window is better if you only need fine end-trim. Because this unit has the -S magnet, you must switch from the legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. The stop screw sets end position only; it does not lock the load on air loss, so add an external rod lock for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X150-100S
- ✓ 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 SUJ50X150-100S FAQ
Yes, the SUJ50X150-100S is discontinued. The direct replacement is the SAUJ50X150-100S, which matches the 50 mm bore, 150 mm nominal stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 100 mm adjust window, allowing you to trim the extend stroke on-site from the 150 mm maximum down to 50 mm. The stop sets end position but is not a load lock.
