This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X75-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X75-40 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.
Airtac SUJ Adjustable Cylinder SUJ32X75-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X75-40 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 SAUJ32X75-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X75-40
The AirTAC SUJ32X75-40 is a double-acting, single-rod profile cylinder with a 32 mm bore and a 75 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, giving a usable extension range of 35 to 75 mm to dial in exact end positions without machining spacers. The extruded aluminum profile barrel is significantly shorter than a standard cylinder of the same bore, making it ideal for space-constrained assemblies. This unit is DISCONTINUED; the exact drop-in replacement is the SAUJ32X75-40, which matches the bore, stroke, force, 1/8" port, and FA/LB mounting.
At 0.5 MPa it delivers 402 N of push force and 345 N of pull, rising to 563 N at 0.7 MPa. A practical computed insight: targeting a safe working load of roughly 241 N (60% of the 0.5 MPa push figure) leaves a solid safety margin, translating to a vertical lift capacity of about 20 kg with a 2:1 factor. Because this SKU lacks a magnet (-S), it cannot accept position sensors. The SAUJ successor upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B switches. Remember the stop screw sets end position but is not a load lock; use an external rod lock for held loads.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

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 SUJ32X75-40 Is Used
Adjustable Clamping Stops
Dialing in the exact clamping distance on a machining fixture where part tolerances vary, using the stop screw to trim the extend stroke by up to 40 mm without swapping cylinders.
Variable Length Reject Arms
Pushing diverter arms on a conveyor line where product lengths change frequently, allowing operators to fine-tune the 35 to 75 mm extend reach on-site for precise sorting.
Compact Packaging Positioners
Indexing flighted packaging lanes in tight machine cells where the short profile barrel saves space and the external stop sets the exact product push-off distance.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X75-40 with the SAUJ32X75-40
To replace the discontinued SUJ32X75-40, order the SAUJ32X75-40 drop-in (insert an A after the leading S). It preserves the 32 mm bore, 75 mm nominal stroke, 1/8" port, M10x1.25 rod thread, and FA/LB mounting. When sizing, verify your force needs: this 32 mm bore gives 402 N push at 0.5 MPa. If you need more force, step up to the 40 mm bore (628 N push @0.5 MPa); if less, drop down accordingly. Select the -40 mm adjust window if your mechanism requires field tuning of the extend stroke between 35 and 75 mm; otherwise, a fixed-stroke SAU is simpler. If you previously used CS1-B/DS1-B sensors, note that the SAUJ requires CMSG/DMSG/EMSG switches, and this specific non-magnet SKU cannot hold any sensor. For strokes of 300 mm or longer, carefully evaluate side-load forces to prevent guide bushing wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X75-40
- ✓ 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 SUJ32X75-40 FAQ
Yes, the AirTAC SUJ32X75-40 is discontinued. The exact drop-in replacement is the SAUJ32X75-40, which offers the same 32 mm bore, 75 mm max stroke, 40 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ also supports modern CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
This double-acting single-rod cylinder has a 32 mm bore, a 1/8" port, and a 75 mm maximum extend stroke that can be shortened by up to 40 mm on-site (usable range 35-75 mm). The force output is 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 stop screw sets end position but is not a load lock.
