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

About the Airtac SUJ Adjustable Cylinder SUJ32X75-40S
The AirTAC SUJ32X75-40S is a discontinued double-acting single-rod profile cylinder with a 32mm bore and 1/8" port. An external stop screw lets you trim the extend stroke by up to 40mm on-site, yielding a usable 35-75mm stroke from the 75mm maximum. It delivers 402N push and 345N pull at 0.5MPa (724N push at 0.9MPa). The drop-in replacement is the SAUJ32X75-40S, retaining the exact bore, force, and SC-series FA/LB mounting.
The SAUJ upgrade transitions from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. For sizing, the 402N push at 0.5MPa implies a safe working load of roughly 241N, or a 20kg vertical lift 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 SAUJ32X75-40S 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 SAUJ32X75-40S 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.
Model Code: Airtac SUJ Adjustable Cylinder SUJ32X75-40S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×75 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ32X75-40S Is Used
Variable Pitch Pushing
Tuning the extend stroke on-site for pushing parts into variable pitch fixtures without swapping the cylinder.
Crash-Safe Forming
Dialing in the exact extend stop during light forming operations to prevent tooling crashes on varied material thicknesses.
Adjustable Diverting
Setting a precise extend length for a conveyor diverting gate that must handle multiple package sizes on the same line.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X75-40S with the SAUJ32X75-40S
To replace the SUJ32X75-40S, order the SAUJ32X75-40S drop-in. If re-sizing, the neighboring bores are 40mm (628N push @0.5MPa) and downgrading is not applicable below 32mm. Choose the 40mm adjust window if your mechanism needs field tuning between 35-75mm. Retain FA or LB mounts, and because this is an -S model, swap legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. For strokes >=300mm, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X75-40S
- ✓ 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 SUJ32X75-40S FAQ
Yes, the SUJ32X75-40S is discontinued. The exact drop-in replacement is the SAUJ32X75-40S, which matches the 32mm bore, 75mm stroke, 40mm adjust window, 1/8" port, and FA/LB mounting. You must upgrade the piston magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 32mm bore has a 1/8" port. The full force set is 402N push / 345N pull @0.5MPa, 563N push @0.7MPa, and 724N push @0.9MPa (max 82kgf @1.0MPa). The 40mm adjust window allows trimming the extend stroke from the 75mm maximum down to 35mm. The stop screw sets end position but is not a load lock.
