This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X40-20, 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 MALJ32X40-20

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-20
The AirTAC MALJ32X40-20 is a discontinued double-acting double-rod mini cylinder with a 20 mm rear stroke adjuster, yielding a usable travel window of 20-40 mm. The direct replacement is the MBLJ32X40-20, matching the bore, stroke, adjust code, G1/8 port and mounting.
This SKU lacks the -S magnet, so it cannot take a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The MALJ uses a fixed rubber bumper and threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body.

| 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 MBLJ32X40-20 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 MBLJ32X40-20 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-20 Is Used
Aluminum Extrusion Notcher
Trim the rear stroke to position a notching blade precisely on an aluminum profile, relying on the fixed rubber bumper to absorb the end-of-stroke impact during repetitive cuts.
Plastic Film Heat Sealer
Adjust the end position to regulate the gap on a packaging film heat sealer, ensuring the 346 N pull force retracts the jaw cleanly without tearing the web.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-20 with MBLJ32X40-20
To replace this MALJ32X40-20, specify the MBLJ32X40-20: confirm the 32 mm bore, 40 mm stroke, 20 mm adjust code, PT G1/8 port, and FA or LB mounting (no back cover or SDB allowed). Because this SKU has no -S magnet, it cannot accept a sensor; the MBLJ upgrade would require CMSG/DMSG/EMSG switches if sensing is added later. The adjuster is a travel stop, not a lock.
The 32 mm rod is M10x1.25.
Upgrade checklist
- ✓ Order the MBLJ32X40-20 (same bore/stroke/adjust)
- ✓ Same 20–40 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 MBLJ32X40-20 instead of this discontinued model.
