This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X225-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X225-40S 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 SUJ100X225-40S 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 SAUJ100X225-40S, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X225-40S is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, giving a usable extend range of 185-225 mm from the 225 mm nominal maximum. The 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N at 0.9 MPa. It features a 1/2" port, M20x1.5 rod thread, and 29 mm adjustable air cushions. This stop screw strictly sets the end position; it is not a load lock, so use an external rod lock for held loads.
This unit is replaced drop-in by the SAUJ100X225-40S, retaining the exact bore, stroke, force, port, and FA/LB mounting. The upgrade path moves from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For sizing, the safe working load is roughly 2356 N (60% of the 0.5 MPa push), equating to a 200 kg vertical lift with a 2:1 margin. The compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.

The SAUJ100X225-40S 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 stop on-site by up to 40 mm allows operators to tune part-forming depth without swapping cylinders.
Set the exact 185-225 mm push-out distance for changing package sizes on a packaging line using the external stop screw.
Trimming the extend stroke mechanically provides a hard, repeatable end position for varying pallet widths.
To replace the discontinued SUJ100X225-40S, order the drop-in SAUJ100X225-40S, keeping the 100 mm bore, 225 mm stroke, 40 mm adjust window, and FA/LB mounts. If re-sizing, the 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N at 0.5 MPa or 7068 N at 0.9 MPa. Choose the 40 mm adjust window when you need precise 185-225 mm extend tuning on-site. Because this model has the -S magnet, swap legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. For this 225 mm stroke, verify side-load limits. Mounting fits the AirTAC SC series only.
Replacement checklist
Yes, the SUJ100X225-40S is discontinued. The exact drop-in replacement is the SAUJ100X225-40S, matching the 100 mm bore, 225 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. You must upgrade the -S magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
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 at 0.9 MPa. The external stop screw trims the extend stroke by up to 40 mm on-site, yielding a 185-225 mm usable range. The stop sets end position only; it is not a load lock.
