This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X500-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X500-75S 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 SUJ32X500-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X500-75S 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 SAUJ32X500-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X500-75S
The AirTAC SUJ32X500-75S is a double-acting, single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 425-500 mm extend window from the 500 mm nominal maximum. The 32 mm bore generates 402 N push and 345 N pull at 0.5 MPa, rising to 563 N at 0.7 MPa, with a 1/8" port and M10x1.25 rod thread. This compact extruded-aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.
This SUJ32X500-75S model is discontinued; the exact drop-in replacement is the SAUJ32X500-75S, sharing the same bore, stroke, force, port, and FA/LB mounting. The legacy CS1-B/DS1-B sensors on this -S magnet model are superseded by current CMSG/DMSG/EMSG switches on the SAUJ. For sizing, a safe working load is roughly 241 N (60% of the 0.5 MPa push), translating to a 20 kg vertical lift with a 2:1 margin. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X500-75S 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 SAUJ32X500-75S 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 SUJ32X500-75S Is Used
Variable Pitch Pushing
Tuning the extend stroke on-site to push parts of varying widths into a press without re-fabricating hard stops.
Adjustable Diverter Arm
Setting precise reach distances on a sorting lane to deflect different package sizes accurately.
Variable Depth Ejector
Trimming the extend end position to eject bins of differing depths from a storage rack safely.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X500-75S with the SAUJ32X500-75S
To replace the discontinued SUJ32X500-75S, use the SAUJ32X500-75S drop-in, which retains the 32 mm bore, 500 mm nominal stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting. When sizing both ways, the neighboring 40 mm bore offers 628 N push at 0.5 MPa if more force is needed, while the smaller bore is unavailable. Choose the 75 mm adjust window if your application requires field-tuning the extend stroke down to 425 mm; the SAUJ beats a fixed SAU plus external stop by integrating this stroke trim cleanly. For the -S magnet, change legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches. At 500 mm stroke, mind side-load and rod-bending forces by supporting the load with external guides.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X500-75S
- ✓ 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 SUJ32X500-75S FAQ
Yes, the SUJ32X500-75S is discontinued. The exact drop-in replacement is the SAUJ32X500-75S, matching the 32 mm bore, 500 mm stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches.
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 window is 75 mm, allowing you to shorten the 500 mm maximum extend stroke down to 425 mm on-site. The stop sets end position and is not a load lock.
