This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X300-75, 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 MALJ32X300-75

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-75
The AirTAC MALJ32X300-75 is a discontinued 32mm bore, double-acting double-rod mini cylinder with a 300mm stroke and a 75mm rear adjustable stroke stopper. This gives a usable end-position window of 225-300mm. The direct replacement is the MBLJ32X300-75, matching the bore, stroke, force, G1/8 port, and mounting.
This SKU lacks the -S magnet option, so it cannot accept a position sensor. It uses a fixed rubber bumper, not an adjustable air cushion. The rear adjuster sets travel but does not hold load without live air pressure. The original MALJ features threaded covers and older CS1-M/DS1-M switches, while the MBLJ upgrade uses a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.

| Stroke | 300 mm |
| Adjustable window | 225 – 300 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |

| 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 MBLJ32X300-75 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 MBLJ32X300-75 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-75 Is Used
Long-Travel Leathern Skiving
Fine-tune the end position without external stops on leather skiving equipment, adjusting the 75mm rear stopper to compensate for material thickness variations.
Carton Flap Plow
Set the exact reach to deflect corrugated carton flaps on a 300mm travel packaging conveyor, relying on the fixed rubber bumper to absorb the end impact.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-75 with MBLJ32X300-75
To replace the MALJ32X300-75, order the exact direct replacement MBLJ32X300-75. Confirm the 32mm bore, 300mm stroke, 75mm adjust code, PT G1/8 port, M10x1.25 rod-end thread, and FA/LB mounting (no back cover or SDB). Because this SKU lacks -S, it cannot take a sensor; if you need position detection, select an MBLJ32X300-75S and use CMSG/DMSG/EMSG switches. The adjuster is a travel stop, not a lock.
At 300mm stroke, the extended 12mm rod is susceptible to bending; ensure rigid guidance to prevent side-load damage.
Upgrade checklist
- ✓ Order the MBLJ32X300-75 (same bore/stroke/adjust)
- ✓ Same 225–300 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 MBLJ32X300-75 instead of this discontinued model.
