This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X175-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X175-30S 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 SUJ100X175-30S 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 SAUJ100X175-30S, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X175-30S is a 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 145-175 mm extend out of the 175 mm nominal maximum. The 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable cushions.
This discontinued unit is fully replaced by the drop-in SAUJ100X175-30S, which matches the bore, stroke, force, port, and FA/LB mounting. The upgrade path moves legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG 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 the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

The SAUJ100X175-30S 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.
Trimming the extend stroke by up to 30 mm on-site allows precise positioning for press fit operations without machining custom spacers.
Adjusting the extend end position lets a diverter gate accommodate different package sizes on a single conveyor line.
Setting a specific 145-175 mm extend endpoint provides a repeatable mechanical stop for pallet positioning before final clamping.
To replace the discontinued SUJ100X175-30S, order the drop-in SAUJ100X175-30S, which preserves the 100 mm bore, 175 mm stroke, 30 mm adjust window, 1/2 inch port, and FA/LB mounting. When sizing both ways, the neighbouring 80 mm bore provides 2513 N push at 0.5 MPa, while the 100 mm bore offers 3927 N. Choose the 30 mm adjust window when you need precise 145-175 mm extend tuning on-site; a fixed SAU plus external stop adds parts and length. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. For strokes at or above 300 mm, verify side-load limits to prevent guide wear. Mounting compatibility is strictly with the AirTAC SC series.
Replacement checklist
Yes, the SUJ100X175-30S is discontinued. The exact drop-in replacement is the SAUJ100X175-30S, matching the 100 mm bore, 175 mm stroke, 30 mm adjust window, and 1/2 inch port. You must upgrade the piston magnet sensors from legacy CS1-B/DS1-B 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 window is 30 mm, allowing you to shorten the 175 mm nominal extend stroke down to 145 mm on-site. The stop sets end position only and is not a load lock.
