This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X500-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X500-75 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.
Airtac SUJ Adjustable Cylinder SUJ32X500-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X500-75 is a double-acting profile-type standard cylinder with a Ø32mm bore and 500mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X500-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X500-75
The AirTAC SUJ32X500-75 is a double-acting single-rod profile cylinder with a 32mm bore and 500mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 75mm on-site, yielding a usable 425-500mm end position. This discontinued unit delivers 402N push and 345N pull at 0.5MPa, operating at 30-800mm/s through a 1/8" port. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
Because the SUJ32X500-75 is discontinued, the exact drop-in replacement is the SAUJ32X500-75, retaining the same profile body, force, and SC-series FA/LB mounts. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B. As a non-magnet SKU, this cylinder cannot take a switch. For 500mm strokes, external guides are recommended to manage rod bending. At 0.5MPa, the safe working load is roughly 241N (60% of push), allowing a 20kg vertical lift with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X500-75 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 SAUJ32X500-75 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.
Where the Airtac SUJ Adjustable Cylinder SUJ32X500-75 Is Used
Variable Depth Boring
Machine tools needing field stroke tuning to adjust the extend reach by up to 75mm for different material thicknesses without swapping cylinders.
Adjustable Transfer Pusher
Sorting lines where the extend stroke must be precisely trimmed on-site to push varying package sizes onto diverging lanes.
Custom Height Diverter
Packaging gates requiring a 425-500mm extend window to deflect items of varying heights at specific angles along a conveyor.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X500-75 with the SAUJ32X500-75
To replace the discontinued SUJ32X500-75, specify the SAUJ32X500-75 drop-in upgrade, which matches the 32mm bore, 500mm stroke, 1/8" port, and FA/LB mounting. The 75mm adjust window is ideal if your extend stroke needs field tuning between 425mm and 500mm. If sizing both ways, the neighbouring 40mm bore yields 628N push at 0.5MPa, while dropping to a shorter stroke avoids the need for external guides to prevent rod bending on this 500mm unit. Since this is a non-magnet SKU, it cannot accept sensors; the SAUJ with a -S suffix uses CMSG/DMSG/EMSG switches (this SUJ used CS1-B/DS1-B). Remember the stop screw sets end position and is not a load lock.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X500-75
- ✓ 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 SUJ32X500-75 FAQ
Yes, the SUJ32X500-75 is discontinued. The exact drop-in replacement is the SAUJ32X500-75, which matches the 32mm bore, 500mm stroke, 1/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
This double-acting single-rod cylinder delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and 724N push at 0.9MPa (max 82kgf at 1.0MPa). The external stop screw provides a 75mm adjust window, allowing you to trim the 500mm extend stroke down to 425mm on-site. The stop sets end position and is not a load lock.
