This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X450-100, 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 MALJ32X450-100

This model is discontinued — the direct replacement is the MBLJ32X450-100.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-100
The AirTAC MALJ32X450-100 is a discontinued double-acting double-rod mini cylinder with a rear adjustable stroke stopper. It provides a usable travel window of 350-450 mm by letting you trim up to 100 mm off the 450 mm stroke. The direct replacement is the MBLJ32X450-100, matching the 32 mm bore, G1/8 port, and mounting footprint.
This SKU lacks the -S magnet, so it cannot accept 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. On long 450 mm strokes, rod side-load must be minimized to prevent bending.

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 MBLJ32X450-100 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 MBLJ32X450-100 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-100 Is Used
Textile Fabric Take-Up
Adjust the rear stop to tune the 450 mm reach on a fabric winding machine, matching roll diameters dynamically while the 12 mm rod handles the tensioning load.
Carton Flap Folder
Trim the stroke by up to 100 mm to accommodate varying box sizes on a packaging line, ensuring the 346 N pull force cleanly folds flaps without crushing the cardboard.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-100 with MBLJ32X450-100
To replace this MALJ32X450-100, install the MBLJ32X450-100. Confirm the 32 mm bore, 450 mm stroke, 100 mm adjust code, G1/8 PT port, and M10x1.25 rod-end thread. Mounting is FA or LB only; there is no back cover or SDB option. Since this SKU has no -S magnet, it cannot take a sensor; if you need position detection on the new unit, specify an MBLJ-S model to use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
Remember the adjuster is a stop, not a lock. At 450 mm, guide the load externally to avoid rod bending.
Upgrade checklist
- ✓ Order the MBLJ32X450-100 (same bore/stroke/adjust)
- ✓ Same 350–450 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 MBLJ32X450-100 instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-100 FAQ
Yes, the MALJ32X450-100 is discontinued. The direct replacement is the MBLJ32X450-100, which matches the 32 mm bore, 450 mm stroke, 100 mm adjust code, and G1/8 port. The MBLJ upgrades the construction with a riveted rolling-packed body instead of threaded covers.
The -100 adjust code lets you trim up to 100 mm at the rear, creating a usable stroke window of 350-450 mm. The adjuster is a travel stop, not a lock, and this no-magnet SKU cannot accept a sensor.
