This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X225-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X225-40 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 SUJ100X225-40 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 SAUJ100X225-40, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X225-40 is a 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, yielding a usable 185-225 mm stroke from the 225 mm nominal maximum. This discontinued unit delivers 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. It features a 100 mm bore, a 25 mm rod, M20x1.5 rod thread, and a 1/2" port. The exact drop-in replacement is the SAUJ100X225-40, which matches the bore, stroke, force, port, and 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 line adds an SAUF built-in-valve variant the SU series lacked. This SKU has no magnet and cannot take a switch. Computed buyer insight: 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. The stop screw sets end position only; it is not a lock, so add an external rod lock for held loads.

The SAUJ100X225-40 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 dial in the exact pressing depth for bearings without swapping cylinders.
Carton erectors needing different flap fold positions can trim the 225 mm extend stroke down to 185 mm to accommodate varying box heights quickly.
Diverting stops on a conveyor can be field-tuned within the 40 mm window to handle mixed product lengths on the same line without reprogramming.
To replace this discontinued SUJ100X225-40, specify the SAUJ100X225-40 drop-in. It preserves the 100 mm bore, 225 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while this 100 mm bore yields 3927 N at 0.5 MPa and 5497 N at 0.7 MPa. Choose the 40 mm adjust window if you need on-site tuning of the extend end position without machining. Because this SKU lacks a magnet, select the -S suffix on the SAUJ if you require position sensing, and pair it with CMSG/DMSG/EMSG switches. For this 225 mm stroke, side-load is minimal, but for strokes >=300 mm ensure guide alignment to prevent rod binding.
Replacement checklist
Yes, the SUJ100X225-40 is discontinued. The exact drop-in replacement is the SAUJ100X225-40, which matches the 100 mm bore, 225 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The double-acting single-rod unit delivers 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 provides a 40 mm adjust window, shortening the extend stroke from 225 mm down to 185 mm. The stop sets end position only and is not a load lock.
