This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X275-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X275-100S 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 SUJ100X275-100S is a double-acting profile-type standard cylinder with a Ø100mm bore and 275mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X275-100S, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X275-100S is a double-acting single-rod profile cylinder with a 100mm bore, 275mm nominal stroke, and a built-in piston magnet. An external stop screw allows you to trim the extend stroke by up to 100mm on-site, yielding a usable extend range of 175-275mm. This bore delivers 3927N push and 3681N pull at 0.5MPa, scaling to 7068N push at 0.9MPa. The 1/2" port and 29mm adjustable cushions manage the 30-800mm/s speed range.
This SUJ model is discontinued and the exact drop-in replacement is the SAUJ100X275-100S, retaining the same force, 1/2" port, and FA/LB mounting. The SAUJ upgrade shifts legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. For sizing, the safe working load is roughly 2356N (60% of the 0.5MPa push), equating to a 200kg vertical lift with a 2:1 margin. Remember the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

The SAUJ100X275-100S 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.
Apply up to 7068N of push force at 0.9MPa for seating components, using the stop screw to fine-tune the 175-275mm extend depth precisely on the machine.
Route varying package sizes on a line by dialing the extend stroke in 1mm increments up to 100mm, avoiding the need to swap the entire cylinder for different box lengths.
Lift loads up to 200kg vertically with a 2:1 safety margin at 0.5MPa, adjusting the extend endpoint on-site to reach different shelf heights without re-plumbing the 1/2" port.
To replace the discontinued SUJ100X275-100S, order the drop-in SAUJ100X275-100S, keeping the 100mm bore, 275mm nominal stroke, and 100mm adjust window. If resizing, the 80mm bore yields 2513N push at 0.5MPa, while the 100mm bore provides 3927N at 0.5MPa. Choose the -100mm adjust window when you need on-site extend trimming from 275mm down to 175mm without changing mounts. Retain FA or LB mounting brackets and note the -S magnet sensor change from CS1-B/DS1-B to CMSG/DMSG/EMSG. The external stop sets end position but is not a lock; add an external rod lock for held loads. For this 275mm stroke, verify side-load alignment to prevent rod binding.
Replacement checklist
Yes, the SUJ100X275-100S is discontinued. The exact drop-in replacement is the SAUJ100X275-100S, which matches the 100mm bore, 275mm stroke, 100mm 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.
It provides 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 100mm on-site, giving a usable 175-275mm range. The stop sets end position only and is not a load lock.
