This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X500-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X500-40 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 SUJ32X500-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X500-40 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 SAUJ32X500-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X500-40
The AirTAC SUJ32X500-40 is a double-acting single-rod profile cylinder with a 500 mm maximum extend stroke and a 40 mm on-site trim window, allowing you to shorten the forward stroke to 460 mm via an external stop screw. This compact extruded-aluminum body is discontinued; the exact drop-in replacement is the SAUJ32X500-40, which matches the 32 mm bore, 1/8" port, and FA/LB mounting. The stop screw sets the end position but is not a load lock.
At 0.5 MPa it delivers 402 N push and 345 N pull, rising to 563 N push at 0.7 MPa. A practical 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 SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here. This non-magnet SKU cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X500-40 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 SAUJ32X500-40 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 SUJ32X500-40 Is Used
Variable Pitch Feed
Adjusting the extend stroke on-site by up to 40 mm allows a single 500 mm cylinder to drive different material lengths without swapping the entire actuator.
Transfer Pusher Tuning
Trimming the forward stroke lets operators fine-tune where parts stop on the belt, accommodating product size changes directly at the machine.
Carton Flap Folding
The external stop screw sets the exact folding depth for various box heights, providing precise end-position control without reprogramming the motion controller.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X500-40 with the SAUJ32X500-40
To replace the discontinued SUJ32X500-40, order the drop-in SAUJ32X500-40, keeping the 32 mm bore, 500 mm max stroke, 40 mm adjust window, and 1/8" port. If sizing both ways, the neighboring 40 mm bore provides 628 N push at 0.5 MPa, while dropping to a smaller bore reduces force. Choose the 40 mm adjust window if your process requires trimming the extend stroke by up to 40 mm on-site; the SAUJ also offers the SAUF built-in-valve variant. For the 500 mm stroke, use FA or LB mounts with external guides to prevent rod bending and manage side loads. Because this SKU lacks a magnet, it cannot accept sensors; if position detection is needed, select an -S SAUJ model and upgrade to CMSG/DMSG/EMSG switches. A plain cylinder drifts on air loss, so fit an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X500-40
- ✓ 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 SUJ32X500-40 FAQ
Yes, the SUJ32X500-40 is discontinued. The exact drop-in replacement is the SAUJ32X500-40, which matches the 32 mm bore, 500 mm stroke, 40 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 double-acting single-rod cylinder delivers 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 provides a 40 mm trim window, allowing the 500 mm extend stroke to be shortened to 460 mm on-site. The stop sets end position and is not a load lock.
