This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X180-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X180-75 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 SUJ100X180-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X180-75 is a double-acting profile-type standard cylinder with a Ø100mm bore and 180mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X180-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X180-75
The AirTAC SUJ100X180-75 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 105-180 mm stroke. This 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. It features a 25 mm rod, M20x1.5 rod thread, 29 mm adjustable cushions, and a 1/2" port.
This SUJ model is discontinued; the exact drop-in replacement is the SAUJ100X180-75, retaining the same force, bore, and FA/LB mounting. The stop screw sets the end position but is not a load lock, so add an external rod lock for held loads. This non-magnet SKU cannot take a sensor, whereas the SAUJ uses current CMSG/DMSG/EMSG sensors (the SUJ used legacy CS1-B/DS1-B). Expect a safe working load of ~2356 N (60% of the 0.5 MPa push) and a ~200 kg vertical lift with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X180-75 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 SAUJ100X180-75 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 SUJ100X180-75 Is Used
Variable Depth Forming
Stamping or pressing parts where the extend stroke needs precise 105-180 mm field tuning to accommodate different material thicknesses without changing the entire cylinder.
Adjustable Diverter Arms
Routing packages of varying sizes on a line by trimming the extend stroke up to 75 mm on-site, ensuring the diverter meets exact package dimensions.
Custom Height Indexing
Lifting loads to specific intermediate heights in a packaging cell, using the external stop screw to set the exact end position for each product run.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X180-75 with the SAUJ100X180-75
To replace the discontinued SUJ100X180-75, order the SAUJ100X180-75 drop-in; it matches the 1/2" port, 75 mm adjust window, and FA/LB mounts. If sizing both ways, the 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore hits 3927 N. The 75 mm window is ideal when exact extend positioning varies. Because this non-magnet SKU lacks sensing, the SAUJ upgrade requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For stroke lengths >=300 mm, verify side-load limits to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X180-75
- ✓ 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 SUJ100X180-75 FAQ
Yes, the SUJ100X180-75 is discontinued. The exact drop-in replacement is the SAUJ100X180-75, which shares the same 100 mm bore, 180 mm stroke, 75 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
This double-acting single-rod cylinder has a 75 mm adjust window, allowing you to shorten the 180 mm extend stroke down to 105 mm on-site. It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The stop screw sets end position but is not a load lock.
