This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X40-40, with the same bore, stroke, output force, port and mounting, so it fits the same application. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-40
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-40 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 0 to 40 mm. This model is discontinued — the direct replacement is the MBLJ32X40-40.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-40
The AirTAC MALJ32X40-40 is a discontinued adjustable-stroke, double-acting mini cylinder. It features a 32mm bore, 40mm stroke, and a rear stopper that trims up to 40mm, yielding a usable end-position window of 0-40mm. The direct replacement is the MBLJ32X40-40, matching the bore, stroke, adjust code, G1/8 port, and mounting.
Two key upgrade facts apply to the MBLJ successor: the older MALJ uses threaded covers, while the MBLJ features a riveted rolling-packed body for greater structural integrity. Additionally, this specific MALJ32X40-40 SKU lacks a magnet (-S), meaning it cannot accept a position sensor. The adjuster functions purely as a travel stop to fine-tune reach without adding external shims; it does not lock the load and cannot hold position without live air pressure. End impact is managed solely by a fixed rubber bumper, as there is no adjustable air cushion.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-40 Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-40 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X40-40 |
| Bore size | Ø32 mm |
| Stroke | 40 mm |
| Adjustable window | 0 – 40 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
The rear adjuster is a travel stop, not a lock — it sets the end position but does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ32X40-40 carries the same ratings.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ32X40-40 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-40 Is Used
Connector Insertion Limit
Prevent over-insertion of delicate ribbon cable connectors by tuning the stroke window to exactly 15mm, leveraging the 0-40mm travel stop for safe, repeatable assembly.
Small Parts Ejector
Fine-tune the ejection stroke on a small bearing housing press to release parts cleanly, relying on the 346N pull force to retract the 12mm rod without bottoming out.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-40 with MBLJ32X40-40
To replace the MALJ32X40-40, order the direct replacement MBLJ32X40-40. Confirm the 32mm bore, 40mm stroke, 40mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB is used). Because this SKU lacks the -S magnet, it cannot hold a sensor; upgrading to an -S MBLJ moves you from the old CS1-M/DS1-M switches to the new CMSG/DMSG/EMSG family. Remember the rear adjuster is a travel stop, not a lock, so an external lock is required for holding loads.
The 40mm stroke here is well below the 500mm maximum standard stroke for a 32mm bore, so rod-bending side-load risks are minimal.
Upgrade checklist
- ✓ Order the MBLJ32X40-40 (same bore/stroke/adjust)
- ✓ Same 0–40 mm adjustable window
- ✓ Adjuster is a stop, not a lock
- ✓ No back cover / SDB — plan an FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check The rear adjuster sets the end position — it is not a load lock.
- check No back-cover / SDB on adjustable-stroke — use FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLJ32X40-40 instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-40 FAQ
Yes, the MALJ32X40-40 is discontinued. The direct replacement is the MBLJ32X40-40, which matches the 32mm bore, 40mm stroke, 40mm adjust code, G1/8 port, and mounting. The MBLJ upgrades the construction from threaded covers to a riveted rolling-packed body.
The 40mm adjuster is a travel stop that creates a 0-40mm usable window, not a lock; it cannot hold a load without live air. This SKU has no magnet, so it cannot take a position sensor.
