This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X500-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X500-30 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 SUJ32X500-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X500-30 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 SAUJ32X500-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X500-30
The AirTAC SUJ32X500-30 is a double-acting single-rod adjustable-stroke profile cylinder, now discontinued and replaced by the drop-in SAUJ32X500-30. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable 470-500 mm stroke window from the 500 mm maximum. This 32 mm bore version features a 1/8" port, a 12 mm rod, and delivers 402 N push / 345 N pull at 0.5 MPa. The stop sets the end position but is not a load lock; use an external rod lock for held loads.
For sizing, the safe working load is roughly 241 N (about 60% of the 402 N push at 0.5 MPa), translating to a vertical lift capacity of about 20 kg with a 2:1 margin. The SAUJ upgrade retains the exact bore, force, port, and FA/LB mounting, but shifts to current CMSG/DMSG/EMSG sensors (this legacy SUJ used CS1-B/DS1-B). As this non-magnet SKU lacks a switch, it cannot take a magnetic sensor. At 500 mm stroke, external guides are recommended to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X500-30 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 SAUJ32X500-30 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 SUJ32X500-30 Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning up to 30 mm to alter part pitch without swapping cylinders.
Adjustable Diverter Gate
Trim the 500 mm extend stroke on-site to change the gate stop position for varying package sizes.
Variable Depth Pusher
Shortens the extend stroke by up to 30 mm to push boxes to different conveyor lane depths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X500-30 with the SAUJ32X500-30
To replace the discontinued SUJ32X500-30, order the drop-in SAUJ32X500-30, which matches the 32 mm bore, 500 mm max stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. When sizing both ways, the neighbouring 40 mm bore offers higher force (628 N push at 0.5 MPa) if you need more thrust, while the 32 mm bore itself provides a safe working load of 241 N (about 20 kg vertical lift with a 2:1 margin). Choose the 30 mm adjust window if you need on-site extend trimming between 470-500 mm. Because this is a non-magnet SKU, it cannot take a sensor; the SAUJ upgrade uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For the 500 mm stroke, add external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X500-30
- ✓ 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 SUJ32X500-30 FAQ
Yes, the SUJ32X500-30 is discontinued. The exact drop-in replacement is the SAUJ32X500-30, sharing the same 32 mm bore, 500 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ 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, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 30 mm on-site, yielding a usable 470-500 mm stroke window. The stop sets end position and is not a load lock.
