This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X300-40, 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 MALJ32X300-40

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-40
The AirTAC MALJ32X300-40 is a discontinued double-acting mini cylinder with a 32 mm bore and 300 mm stroke. It features a 40 mm rear adjuster, creating a usable stroke window of 260-300 mm. The direct replacement is the MBLJ32X300-40, matching bore, stroke, port and force.
This SKU has no magnet (-S), so it cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it will not hold a load without live air pressure. The fixed rubber bumper softens end impact, but unlike the current-line MBLC, there is no adjustable air cushion. Upgrading to the MBLJ moves from threaded covers to a riveted rolling-packed body.

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 MBLJ32X300-40 carries the same ratings.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

| 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 MBLJ32X300-40 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-40 Is Used
Textile Loom Beam Loader
Fine-tunes the end position to seat heavy warp beams into loom cradles, absorbing impact with the fixed rubber bumper while avoiding hard mechanical crashes.
Wood Router Fence Stop
Sets a precise rear travel limit on an automated router fence, trimming up to 40 mm off the 300 mm stroke to match custom cabinet door profiles without external stops.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-40 with MBLJ32X300-40
Replace this MALJ32X300-40 with the exact direct replacement MBLJ32X300-40. Confirm the 32 mm bore, 300 mm stroke, 40 mm adjust code, G1/8 port, PT threads and FA/LB mounting (no back cover or SDB). Because this SKU lacks the -S magnet, it cannot take a sensor; if you need position feedback, step up to an MBLJ32X300-40S and use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
At 300 mm stroke, the 12 mm rod is susceptible to side-load bending; keep the load guided to prevent premature seal wear. Remember the adjuster sets end position but does not lock the load.
Upgrade checklist
- ✓ Order the MBLJ32X300-40 (same bore/stroke/adjust)
- ✓ Same 260–300 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 MBLJ32X300-40 instead of this discontinued model.
