This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X180-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X180-100 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.

The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X180-100 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 SAUJ100X180-100, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X180-100 is a double-acting single-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 80 to 180 mm stroke. This discontinued 100 mm bore model delivers a 3927 N push and 3681 N pull at 0.5 MPa, rising to 7068 N at 0.9 MPa, and features a 1/2" port with a 25 mm rod. The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads.
The exact drop-in replacement is the SAUJ100X180-100, retaining the same bore, stroke, force, port, and FA/LB mounting. This base SKU lacks a magnet and cannot take a switch, whereas the SAUJ upgrade path supports modern CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For sizing, a safe working load is roughly 2356 N (about 60% of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin.

The SAUJ100X180-100 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.
Dial in the exact 80 to 180 mm extend position on-site for pressing assemblies without machining custom spacers.
Tune the extend stop to accommodate different package sizes on a packaging line without swapping the cylinder.
Set precise end positions for pallet routing gates where the required reach varies by pallet depth.
To replace the discontinued SUJ100X180-100, order the drop-in SAUJ100X180-100, which preserves the 180 mm nominal stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. Because this specific SKU has no magnet, it cannot accept a sensor; if sensing is needed, move to an SAUJ-S variant and use current CMSG/DMSG/EMSG switches rather than the obsolete CS1-B/DS1-B. When sizing both ways, the neighbouring 80 mm bore provides 2513 N push at 0.5 MPa, while the 100 mm bore offers 3927 N at 0.5 MPa or 5497 N at 0.7 MPa. The 100 mm adjust window is ideal when the final extend position must be dialed in on-site, often beating a fixed SAU plus external stop. For strokes of 300 mm or longer, verify the side-load limits to prevent rod distortion.
Replacement checklist
Yes, the SUJ100X180-100 is discontinued. The exact drop-in replacement is the SAUJ100X180-100, which matches the 100 mm bore, 180 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also supports the SAUF built-in-valve variant and uses current CMSG/DMSG/EMSG sensors.
The 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N at 0.9 MPa, and a max of 801 kgf at 1.0 MPa. The external stop screw lets you trim the extend stroke by up to 100 mm on-site, giving a usable 80 to 180 mm stroke. The stop sets end position only; it is not a load lock.
