This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X275-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X275-75 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 SUJ100X275-75 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 SAUJ100X275-75, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X275-75 is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 200-275 mm stroke from the 275 mm nominal maximum. This 100 mm bore generates 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. It features a 25 mm rod, M20x1.5 rod thread, 29 mm adjustable air cushions, and a 1/2" port.
This SUJ unit is discontinued; the exact drop-in replacement is the SAUJ100X275-75, retaining the same bore, stroke, force, port, and SC-series FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG switches (this SKU lacks a magnet and cannot take a switch, while legacy -S SUJ used CS1-B/DS1-B). For sizing, a 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 stop screw sets end position only—it is not a load lock; use an external rod lock for held loads.

The SAUJ100X275-75 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.
Uses the 75 mm adjust window to tune the extend stroke on-site for different material thicknesses, relying on the 7068 N push at 0.9 MPa to seat parts firmly.
Trims the extend stroke down to 200 mm to accommodate varying box sizes on the line without re-mounting the cylinder, using the 29 mm cushions to decelerate the 25 mm rod.
Dial in specific extend heights up to 275 mm for multi-level sorting, safely lifting up to 200 kg vertically with a 2:1 margin at 0.5 MPa.
To replace this discontinued SUJ100X275-75, specify the SAUJ100X275-75 drop-in: it keeps the 100 mm bore, 275 mm max stroke, 75 mm adjust window, 1/2" port, and FA/LB mounts. When sizing both ways, the neighboring 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N at 0.5 MPa. Choose the 75 mm adjust window when you need on-site extend trimming between 200 and 275 mm, which often beats installing a fixed-stroke SAU plus an external stop. Because this exact SKU lacks a magnet, it cannot accept a switch; if sensing is needed, move to the SAUJ and select CMSG/DMSG/EMSG sensors. For this 275 mm stroke, verify side-load limits on the 25 mm rod. Remember, the stop screw sets end position but does not lock the load on air loss—add an external rod lock for holding.
Replacement checklist
Yes, the SUJ100X275-75 is discontinued. The exact drop-in replacement is the SAUJ100X275-75, which matches the 100 mm bore, 275 mm max stroke, 75 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors.
This double-acting single-rod cylinder has a 75 mm adjust window, allowing the extend stroke to be trimmed on-site from 275 mm down to 200 mm. Force output is 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. It uses a 1/2" port.
