This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X500-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X500-20 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 SUJ32X500-20
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X500-20 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 SAUJ32X500-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X500-20
The AirTAC SUJ32X500-20 is a double-acting, single-rod profile cylinder with a 500 mm nominal stroke and a 20 mm adjustable extend window. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 480-500 mm stroke. The stop sets the end position but is not a load lock. This 32 mm bore delivers 402 N push and 345 N pull at 0.5 MPa, features a 1/8" port, and uses adjustable 21 mm cushions.
This SUJ model is discontinued; the exact drop-in replacement is the SAUJ32X500-20, sharing the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. This non-magnet SKU cannot take a sensor. For sizing, a safe working load is roughly 241 N (60% of the 0.5 MPa push), equating to a 20 kg vertical lift with a 2:1 margin. Note: at 500 mm, external guides are advised to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X500-20 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 SAUJ32X500-20 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 SUJ32X500-20 Is Used
Diverting Gate Adjustment
Tuning a diverting gate on a conveyor line where the exact extend position must be dialed in by 10-20 mm during installation to match varying package sizes without re-engineering the mount.
Light Press Positioning
Setting the end-of-stroke contact point on a light assembly press, allowing operators to trim the 500 mm extend down by up to 20 mm to accommodate different jig heights.
Variable Depth Stops
Actuating a variable depth stop in a warehousing fixture where the effective extend length needs minor on-site adjustment to handle different pallet widths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X500-20 with the SAUJ32X500-20
To replace the discontinued SUJ32X500-20, order the drop-in SAUJ32X500-20, which matches the 32 mm bore, 500 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounts. When sizing, the 32 mm bore yields 402 N push at 0.5 MPa (safe load ~241 N); if more force is needed, the neighboring 40 mm bore provides 628 N. The 20 mm adjust window is ideal for field-tuning the extend end position without machining. Because this is a non-magnet SKU, it cannot accept sensors; if sensing is required, select an SAUJ with the -S suffix and use CMSG/DMSG/EMSG switches. For the 500 mm stroke, use external guides to manage side loads and prevent rod bending. Remember, the stop screw sets end position but does not lock the load on air loss—use an external rod lock for holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X500-20
- ✓ 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 SUJ32X500-20 FAQ
Yes, the SUJ32X500-20 is discontinued. The exact drop-in replacement is the SAUJ32X500-20, which shares the same 32 mm bore, 500 mm stroke, 20 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 switches.
This 32 mm bore double-acting single-rod cylinder 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 (theoretical max 82 kgf at 1.0 MPa). The external stop screw allows you to trim the extend stroke by up to 20 mm on-site, giving a usable 480-500 mm stroke. The stop sets end position and is not a load lock.
