This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X75-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X75-20S 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 SUJ32X75-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 75mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X75-20S, which matches its bore, stroke, force and mounting.
The AirTAC SUJ32X75-20S is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 55-75 mm extend out of the 75 mm nominal maximum. Built for compact layouts, its extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This bore delivers 402 N push and 345 N pull at 0.5 MPa, rising to 563 N push at 0.7 MPa, with a 1/8" port and M10x1.25 rod thread.
Because the SUJ line is end-of-life, the exact drop-in replacement is the SAUJ32X75-20S, matching the bore, stroke, force, port, and FA/LB mounting. The upgrade path moves the -S magnet sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For sizing, a safe working load is roughly 241 N (60% of the 0.5 MPa push), translating to a vertical lift capacity of about 20 kg with a 2:1 margin. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X75-20S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X75-20S 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.
Testing stations needing precise probe contact can field-tune the extend stroke by up to 20 mm to accommodate different product heights without swapping cylinders.
Diverter gates on conveyors handling mixed carton sizes use the adjustable stop to set the exact push distance on-site for each format changeover.
Warehousing pushers that must adapt to varying box depths benefit from the external stop screw to trim the extend stroke dynamically at the fixture.
To replace the SUJ32X75-20S, order the SAUJ32X75-20S, which is a true drop-in for the 32 mm bore, 75 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. When sizing both ways, the neighboring 40 mm bore offers higher force (628 N push @0.5 MPa) if you need more thrust, while the 32 mm bore here provides 402 N push @0.5 MPa. Select the 20 mm adjust window if you need on-site extend trimming between 55 and 75 mm; this mechanism sets the end position and does not hold the load on air loss, so specify an external rod lock for vertical holding. For the -S magnet version, note the sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG. Although this stroke is under 300 mm, always verify side-load limits on longer strokes.
Replacement checklist
Yes, the SUJ32X75-20S is discontinued. The exact drop-in replacement is the SAUJ32X75-20S, which matches the 32 mm bore, 75 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ also upgrades the -S magnet sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
This double-acting single-rod cylinder delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The external stop screw provides a 20 mm adjust window, allowing you to shorten the 75 mm nominal extend stroke down to 55 mm on-site. The stop sets end position but is not a load lock.
