This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X225-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X225-75S 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 SUJ100X225-75S is a double-acting profile-type standard cylinder with a Ø100mm bore and 225mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X225-75S, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X225-75S is a double-acting single-rod profile cylinder with a 100mm bore and 225mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 75mm on-site, yielding a usable 150-225mm extension. This bore delivers 3927N push and 3681N pull at 0.5MPa, climbing to 7068N push at 0.9MPa. The 1/2" port and M20x1.5 rod thread handle high flow, while the 29mm adjustable cushions manage kinetic energy.
This unit is discontinued; the exact drop-in replacement is the SAUJ100X225-75S, retaining the bore, stroke, 801kgf max force, and FA/LB mounting. For sizing, a safe working load is roughly 2356N (60% of the 0.5MPa push), equating to a 200kg vertical lift with a 2:1 margin. Note the stop screw sets end position but is not a load lock; drift occurs on air loss without an external rod lock. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors, which must change to current CMSG/DMSG/EMSG switches on the SAUJ successor.

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.
Trimming the extend stroke by up to 75mm on-site allows precise positioning for pressing operations where material thickness varies, avoiding the need to physically shim the machinery.
Diverter mechanisms on packaging lines can field-tune the extend length between 150mm and 225mm to accommodate different product box sizes without swapping the cylinder.
Indexing pushes into storage racks can be dialed in exactly using the external stop screw, setting the end position firmly for varying pallet depths before retracting.
To replace the discontinued SUJ100X225-75S, order the SAUJ100X225-75S drop-in: it preserves the 100mm bore, 225mm nominal stroke, 75mm adjust window, 1/2" port, and FA/LB/Basic mounts. When sizing both ways, the neighboring 80mm bore yields 2513N push at 0.5MPa, while this 100mm bore provides 3927N. If your application needs the full 7068N push at 0.9MPa, do not downsize. Choose the 75mm adjust window if your mechanism requires precise 150-225mm extend tuning; a fixed SAU cylinder plus external stop is bulkier. Because this unit has a piston magnet (-S), you must migrate from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. For strokes of 300mm or longer, verify side-load guidance to prevent rod binding.
Replacement checklist
Yes, the SUJ100X225-75S is discontinued. The exact drop-in replacement is the SAUJ100X225-75S, which matches the 100mm bore, 225mm stroke, 75mm adjust window, 1/2" port, and FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The 100mm bore provides 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, and 7068N push at 0.9MPa (801kgf max at 1.0MPa). The external stop screw provides a 75mm adjustment window, allowing the extend stroke to be shortened from the 225mm maximum down to 150mm on-site. The stop sets end position and is not a load lock.
