This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X80-50, 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 MALJ32X80-50
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-50 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 30 to 80 mm. This model is discontinued — the direct replacement is the MBLJ32X80-50.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-50
The AirTAC MALJ32X80-50 is a discontinued double-acting mini cylinder with a 32mm bore and an 80mm standard stroke. The rear screw stopper lets you trim up to 50mm of travel, creating a usable end-position window of 30-80mm. The direct replacement is the MBLJ32X80-50, which matches the bore, stroke, G1/8 port, and mounting footprint.
This SKU lacks the -S magnet option, 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 newer MBLJ upgrades to a riveted rolling-packed body. If you need position feedback on the replacement, you must step up to an MBLJ32X80-50S and use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.

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 MBLJ32X80-50 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 MBLJ32X80-50 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-50 Is Used
PCB Depaneling Saw
Dials the 30-80mm blade plunge depth precisely.
Carton Flap Folder
Adjusts the 32mm rod reach on packaging lines for varying box heights. The fixed rubber bumper absorbs the repeated end-impact of high-speed folding without needing an air cushion.
Aluminum Profile Stopper
Acts as a depth stop on a 40mm extrusion cutting jig. You can trim the 80mm stroke down to 30mm on the fly to match custom profile lengths without adding external hardware.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-50 with MBLJ32X80-50
To replace this MALJ32X80-50, order the MBLJ32X80-50. Confirm the 32mm bore, 80mm stroke, 50mm adjust code, G1/8 port, and PT thread. Mounting is Basic, FA, or LB only; there is no back-cover or SDB option. Remember the adjuster sets the stroke but does not lock the load mechanically.
Upgrade checklist
- ✓ Order the MBLJ32X80-50 (same bore/stroke/adjust)
- ✓ Same 30–80 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 MBLJ32X80-50 instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-50 FAQ
Yes, the MALJ32X80-50 is discontinued. The direct replacement is the MBLJ32X80-50, which retains the 32mm bore, 80mm stroke, 50mm adjust code, and G1/8 port. The MBLJ upgrades the threaded covers to a riveted rolling-packed body.
The usable stroke window is 30-80mm, set by trimming the rear stopper up to 50mm. At 0.5MPa it pushes with 402N and pulls with 346N. At 0.7MPa the push force is 563N, and the maximum force is 82kgf at 1.0MPa. This stopper only sets the end position; it does not hold the load without air pressure.
