This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X180-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X180-100S 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 SUJ100X180-100S 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 SAUJ100X180-100S, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X180-100S is a discontinued double-acting single-rod adjustable-stroke profile cylinder. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 80-180 mm extend range from the 180 mm nominal maximum. The stop screw sets the end position; it is not a load lock. This 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, rising to 7068 N push at 0.9 MPa, via a 1/2" port and 25 mm rod.
The exact drop-in replacement is the SAUJ100X180-100S, retaining the bore, stroke, force, port, and FA/LB mounting. The computed 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. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S magnet model. A plain cylinder drifts on air loss; use an external rod lock for held loads.

The SAUJ100X180-100S 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.
Stamping or pressing applications where the material thickness fluctuates, using the 100 mm adjust screw to tune the extend stroke on-site without swapping cylinders.
Routing different package sizes on a line by trimming the actuator extend stroke from 180 mm down to 80 mm to hit varying lane widths precisely.
Pushing variable product counts into a cartoning station, dialing in the exact end position via the external stop screw to accommodate different box dimensions.
To replace the discontinued SUJ100X180-100S, order the drop-in SAUJ100X180-100S, keeping the 100 mm bore, 180 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounts. When sizing both ways, the 80 mm neighbour bore gives 2513 N push at 0.5 MPa, while the 63 mm bore yields 1559 N. Choose the 100 mm adjust window when you need maximum field flexibility to shorten the extend stroke down to 80 mm. For the -S magnet option, swap legacy CS1-B/DS1-B sensors for current CMSG/DMSG/EMSG switches. At 180 mm stroke, side-load is minimal, but for any stroke over 300 mm, verify guide alignment to prevent rod binding.
Replacement checklist
Yes, the SUJ100X180-100S is discontinued. The exact drop-in replacement is the SAUJ100X180-100S, which matches the 100 mm bore, 180 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. You must update your sensors: the SAUJ uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B reed sensors.
The 100 mm bore provides 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. The external stop screw offers a 100 mm adjust window, allowing you to shorten the 180 mm nominal extend stroke down to 80 mm on-site. The stop sets end position only; it is not a load lock.
