This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X100-20, 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 MALJ32X100-20
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X100-20 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 80 to 100 mm. This model is discontinued — the direct replacement is the MBLJ32X100-20.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X100-20
The AirTAC MALJ32X100-20 is a discontinued double-acting mini cylinder with a 32 mm bore and a 100 mm stroke. It features a rear screw stopper that lets you trim up to 20 mm off the stroke, giving a usable end-position window of 80-100 mm. The direct replacement is the MBLJ32X100-20, which matches the bore, stroke, adjust code, and G1/8 port.
This SKU has no -S magnet, so it cannot accept a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The original MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body. Impact is softened by the bumper only, so external flow controls are needed to manage shock.

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 MBLJ32X100-20 carries the same ratings.
Theoretical Output Force (Ø32mm)

| 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 MBLJ32X100-20 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X100-20 Is Used
Aluminum Extrusion Notcher
Fine-tune the cutting depth on an aluminum profile notching station by trimming 20 mm off the stroke, preventing the 12 mm rod from bottoming out harshly against the fixed rubber bumper.
Carton Flap Folder
Adjust the reach on a packaging line flap folder to handle varying box heights, relying on the 346 N pull force to retract the mechanism cleanly between cycles.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X100-20 with MBLJ32X100-20
To replace this MALJ32X100-20, order the MBLJ32X100-20. Confirm the 32 mm bore, 100 mm stroke, 20 mm adjust code, G1/8 port, PT thread, and Basic/FA/LB mounting (no back cover or SDB). Because this SKU lacks a magnet, you lose the CS1-M/DS1-M sensor option; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you need position feedback. Remember the rear adjuster is a stop, not a lock, for holding loads.
At 100 mm stroke, keep the rod side-load minimal to prevent bending the 12 mm rod.
Upgrade checklist
- ✓ Order the MBLJ32X100-20 (same bore/stroke/adjust)
- ✓ Same 80–100 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 MBLJ32X100-20 instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X100-20 FAQ
Yes, the MALJ32X100-20 is discontinued. The direct replacement is the MBLJ32X100-20, which matches the 32 mm bore, 100 mm stroke, 20 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The usable stroke window is 80-100 mm, set by trimming up to 20 mm via the rear stopper. At 0.5 MPa it pushes with 402 N and pulls with 346 N. At 0.7 MPa the push force is 563 N, and the maximum force is 82 kgf at 1.0 MPa. The rear adjuster is a travel stop, not a lock.
