This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X75-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X75-20 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.
Airtac SUJ Adjustable Cylinder SUJ32X75-20
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X75-20 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 SAUJ32X75-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X75-20
The AirTAC SUJ32X75-20 is a 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, giving a usable forward travel of 55-75 mm. This discontinued 32 mm bore unit delivers 402 N push and 345 N pull at 0.5 MPa, operates at 30-800 mm/s, and uses a 1/8" port with an M10x1.25 rod thread. The stop sets the end position; it is not a load lock, so use an external rod lock for held loads.
The direct drop-in replacement is the SAUJ32X75-20, matching the 75 mm maximum stroke, force, and FA/LB mounting. Upgrading to the SAUJ moves sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors, though this specific non-magnetic SUJ SKU cannot take a switch. For sizing, the 402 N push at 0.5 MPa yields a safe working load of roughly 241 N (about 60 percent of rated force), translating to a 20 kg vertical lift with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X75-20 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X75-20 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.
Where the Airtac SUJ Adjustable Cylinder SUJ32X75-20 Is Used
Gauge Positioning Stops
Trimming the 75 mm extend stroke by up to 20 mm on-site allows operators to dial in exact 55-75 mm probe contact points without swapping cylinders.
Light Clamping Fixtures
The 32 mm bore provides a 241 N safe working load at 0.5 MPa, ideal for applying adjustable clamping force to delicate workpieces where the stroke must be finely tuned.
Transfer Diverter Arms
Field-tuning the extend stop lets maintenance teams adjust diverter arm reach on the line, accommodating product size changes quickly using the 1/8" ported body.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X75-20 with the SAUJ32X75-20
To replace the discontinued SUJ32X75-20, order the drop-in SAUJ32X75-20, which preserves the 32 mm bore, 75 mm nominal stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. If you need to resize, the neighboring 40 mm bore gives 628 N push at 0.5 MPa, while dropping down reduces the footprint. Choose the 20 mm adjust window when you need precise on-site end-position tuning between 55 and 75 mm; the external stop screw sets this forward end position but does not lock the load, so add an external rod lock for vertical holding. Because this non-magnetic SKU lacks a switch, migrating to the SAUJ enables modern CMSG/DMSG/EMSG sensors if you add the -S suffix. For strokes of 300 mm or longer, verify your side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X75-20
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SUJ Adjustable Cylinder SUJ32X75-20 FAQ
Yes, the SUJ32X75-20 is discontinued. The exact drop-in replacement is the SAUJ32X75-20, which matches the 32 mm bore, 75 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The 32 mm bore provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and 724 N push at 0.9 MPa, with a theoretical max of 82 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 20 mm on-site, yielding a usable forward travel of 55-75 mm. The stop sets end position but is not a load lock.
