This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X120-30STC — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X120-30STC 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 SUJ100X120-30STC is a double-acting profile-type standard cylinder with a Ø100mm bore and 120mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X120-30STC, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X120-30STC is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 90-120 mm stroke out of the 120 mm nominal maximum. The 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, rising to 7068 N at 0.9 MPa. It features a 1/2" port, a Ø25 mm rod, and 29 mm adjustable cushions. The TC mount interface uses an SC-series accessory.
This unit is discontinued; the exact drop-in replacement is the SAUJ100X120-30STC, retaining the same force, bore, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B switches. 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 that the stop screw sets end position but is not a load lock; drift occurs on air loss without an external rod lock.

The SAUJ100X120-30STC 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.
Adjusts the extend stop on-site by up to 30 mm to accommodate varying material thicknesses in a compact crushing press without re-engineering the fixture.
Trims the actuation length on a packaging conveyor diverter gate to handle different carton depths dynamically on the factory floor.
Sets a precise mechanical end position for a heavy warehouse pusher that must adapt to multiple pallet sizes while relying on the 100 mm bore force.
To replace the discontinued SUJ100X120-30STC, specify the SAUJ100X120-30STC drop-in. It matches the 100 mm bore, 120 mm nominal stroke, 1/2" port, and TC/FA/LB SC-series mounting. When sizing both ways, the neighboring 80 mm bore yields 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N at 0.5 MPa or 5497 N at 0.7 MPa. Choose the 30 mm adjust window if your mechanism requires field-tuning the extend stroke down to 90 mm; for fixed 120 mm travel, a standard SAU cylinder suffices. Because this model has the -S magnet, upgrade your position sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
Yes, the AirTAC SUJ100X120-30STC is discontinued. The exact drop-in replacement is the SAUJ100X120-30STC, which matches the 100 mm bore, 120 mm stroke, 1/2" port, and TC/FA/LB SC-series mounting. You must upgrade your position sensors from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG series.
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, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw provides a 30 mm adjust window, allowing you to shorten the 120 mm nominal extend stroke down to 90 mm on-site. This stop sets the end position but is not a load lock.
