This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X175-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X175-50S 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 SUJ100X175-50S is a double-acting profile-type standard cylinder with a Ø100mm bore and 175mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X175-50S, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X175-50S is a discontinued double-acting single-rod profile cylinder with a 100mm bore and 175mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 50mm on-site, yielding a usable 125-175mm window. It features a 1/2 inch port, M20x1.5 rod thread, and 29mm adjustable cushions. This unit is discontinued; the exact drop-in replacement is the SAUJ100X175-50S, matching the bore, stroke, 1/2 inch port, and SC-series FA/LB mounting.
The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here, and the SAU family adds an SAUF built-in-valve variant the SU line lacked. At 0.5MPa it delivers 3927N push and 3681N pull, climbing to 7068N push at 0.9MPa. A computed buyer insight: the safe working load is roughly 2356N (60% of the 0.5MPa push), allowing a vertical lift of about 200kg with a 2:1 margin. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

The SAUJ100X175-50S 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.
Adjusting the extend stroke on-site by up to 50mm allows a single 100mm bore cylinder to drive multiple product pitches without swapping the whole actuator.
Trimming the extend stroke lets operators dial in the exact push distance for varying package sizes on a transfer line, using the 125-175mm window.
The external stop screw provides a hard mechanical end position for pallet stops, offering field flexibility without re-mounting the cylinder.
To replace this discontinued model, order the SAUJ100X175-50S; it is a true drop-in swap retaining the 100mm bore, 175mm nominal stroke, 1/2 inch port, and FA/LB mounting. When sizing both ways, the neighbouring 80mm bore yields 2513N push at 0.5MPa, while the 100mm bore provides 3927N at 0.5MPa or 7068N at 0.9MPa. Choose the 50mm adjust window if your fixture needs field tuning between 125mm and 175mm extend lengths. Because this is an -S model, you must migrate from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300mm or longer, verify side-load limits to prevent guide wear. The external stop sets end position only; it is not a lock, so add an external rod lock for load holding.
Replacement checklist
Yes, the SUJ100X175-50S is discontinued. The exact drop-in replacement is the SAUJ100X175-50S, which matches the 100mm bore, 175mm nominal stroke, 1/2 inch port, and FA/LB mounting. The SAUJ upgrades the sensor track to current CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B.
It delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, and 7068N push at 0.9MPa, with a theoretical max of 801kgf at 1.0MPa. The external stop screw trims the extend stroke by up to 50mm on-site, giving a usable window of 125-175mm. The stop sets end position only and is not a load lock.
