This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X225-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X225-75 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 SUJ100X225-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X225-75 is a double-acting profile-type standard cylinder with a Ø100mm bore and 225mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X225-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X225-75
The AirTAC SUJ100X225-75 is a double-acting, single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 150-225 mm stroke. The nominal 225 mm is the maximum extension. At 0.5 MPa this 100 mm bore generates 3927 N push and 3681 N pull force, peaking at 7068 N push at 0.9 MPa. It features a 25 mm rod, M20x1.5 rod thread, and a 1/2" port.
This SUJ model is discontinued; the exact drop-in replacement is the SAUJ100X225-75, which retains the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. Because this specific SKU lacks a magnet, it cannot take a magnetic switch. For sizing, a safe working load is roughly 2356 N (60% of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. Note the stop screw sets end position only; it is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X225-75 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 SAUJ100X225-75 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.

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 SUJ100X225-75 Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning up to 75 mm to alter product pitch without swapping cylinders.
Adjustable Diverter Gate
Sets precise divert end positions on the fly for varying package widths on a 1/2" port pneumatic line.
Custom Stack Height Stop
Trims the extend stroke to hit intermediate stack heights while using the full 225 mm nominal retraction.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X225-75 with the SAUJ100X225-75
To replace the discontinued SUJ100X225-75, specify the SAUJ100X225-75 drop-in: it keeps the 1/2" port, 75 mm adjust window, and 7068 N push at 0.9 MPa. When sizing both ways, the neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N at 0.5 MPa. Choose the 75 mm adjust window if your end position varies by up to 75 mm; the stop screw sets this end position but is not a lock. Mounting uses FA or LB brackets (SC-series compatible). Because this SKU has no magnet, it cannot support sensing; the SAUJ with a -S suffix enables CMSG/DMSG/EMSG sensors. For stroke lengths of 300 mm or more, verify side-load limits. For held loads, add an external rod lock or pilot-operated check valve.
