This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X150-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X150-50 in place of this model. 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 SUJ100X150-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X150-50 is a double-acting profile-type standard cylinder with a Ø100mm bore and 150mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X150-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X150-50
The AirTAC SUJ100X150-50 is a double-acting single-rod adjustable-stroke profile cylinder, now discontinued and superseded by the drop-in SAUJ100X150-50. It features a 100mm bore, 1/2" port, and an external stop screw that lets you trim the extend stroke by up to 50mm on-site, yielding a usable 100-150mm extend range from the 150mm nominal maximum. This stop screw strictly sets the end position and is not a load lock; external rod locks are required for held loads. The profile barrel is shorter than an ISO 15552 cylinder of the same bore.
At 0.5 MPa it delivers 3927N push and 3681N pull force, scaling to 7068N push at 0.9 MPa. A practical computed insight: the safe working load is roughly 2356N (about 60% of the 0.5MPa push figure), translating to a 200kg vertical lift with a 2:1 margin. Upgrading to the SAUJ100X150-50 retains the exact bore, stroke, force, and FA/LB mounting, but shifts sensing to current CMSG/DMSG/EMSG sensors (this legacy SUJ used CS1-B/DS1-B). This specific SKU lacks a magnet, so it cannot accept a magnetic switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X150-50 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 SAUJ100X150-50 produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | 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 SUJ100X150-50 Is Used
Variable Depth Boring
Adjusting the extend stroke by up to 50mm on-site allows operators to fine-tune boring depth without swapping cylinders.
Variable Length Diverter
Trimming the extend stroke dynamically accommodates different package sizes on a sorting line.
Adjustable Height Stopper
Sets precise mechanical end positions for varying pallet heights while utilizing the full 3927N push force at 0.5 MPa.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X150-50 with the SAUJ100X150-50
To replace the discontinued SUJ100X150-50, order the exact drop-in SAUJ100X150-50, which matches the 100mm bore, 150mm stroke, 50mm adjust window, 1/2" port, and FA/LB mounting. If resizing, neighboring bores offer different 0.5 MPa forces: the 80mm bore provides 2513N push, while the 100mm bore provides 3927N push. Choose the 50mm adjust window if you need to trim the extend stroke on-site by up to 50mm; for fixed positioning, a standard SAU cylinder suffices. Because this SKU has no magnet, it cannot accept sensors; if position detection is needed, select an SAUJ with the -S suffix and use CMSG/DMSG/EMSG switches. For strokes of 300mm or longer, verify side-load limits to prevent rod binding. Remember that the adjustable stop sets end position but does not lock the load—use an external rod lock for pneumatic load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X150-50
- ✓ 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 SUJ100X150-50 FAQ
Yes, the SUJ100X150-50 is discontinued. The exact drop-in replacement is the AirTAC SAUJ100X150-50, which matches the 100mm bore, 150mm stroke, 50mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors, whereas this legacy SUJ used CS1-B/DS1-B switches.
The double-acting single-rod cylinder has a 50mm adjust window, allowing you to shorten the 150mm nominal extend stroke down to 100mm on-site. It provides 3927N push and 3681N pull at 0.5 MPa, 5497N push at 0.7 MPa, and 7068N push at 0.9 MPa. The external stop screw sets the end position but is not a load lock.
