This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X400-75, 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 MALJ32X400-75
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-75 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 325 to 400 mm. This model is discontinued — the direct replacement is the MBLJ32X400-75.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-75
The AirTAC MALJ32X400-75 is a discontinued double-acting double-rod mini cylinder with a 32mm bore and 400mm stroke. The -75 adjust code lets you trim the rear end position by up to 75mm, creating a usable stroke window of 325-400mm. The direct replacement is the MBLJ32X400-75, matching the G1/8 port, M10x1.25 rod thread, and 82kgf max force.
This SKU lacks a magnet (-S), 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. Two upgrade facts define the MBLJ successor: it replaces the MALJ's threaded covers with a riveted rolling-packed body, and if you later need sensors, the old CS1-M/DS1-M switches are superceded by CMSG/DMSG/EMSG series. Impact is absorbed solely by a fixed rubber bumper, as there is no adjustable air cushion.

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 MBLJ32X400-75 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 MBLJ32X400-75 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-75 Is Used
PCB Router Z-Axis Depth Stop
Dial in the exact 325-400mm plunge on a PCB depaneling router.
Long-Stroke Pallet Pusher
Ejects 400mm pallets from a machining center. The 346N pull force retracts the arm safely, and the fixed rubber bumper absorbs the shock of repeated end-of-stroke impacts.
Carton Flap Folder
Folds large corrugated flaps on a packaging line. The 75mm adjust window lets mechanics fine-tune the fold radius on the fly to match varying box heights without swapping hardware.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-75 with MBLJ32X400-75
To replace this MALJ32X400-75, order the MBLJ32X400-75. Confirm the 32mm bore, 400mm stroke, -75 adjust code, G1/8 PT port, and M10x1.25 rod-end thread. Mounting remains Basic, FA, or LB only, as there is no back-cover or SDB option. Because this is a no-S SKU, it cannot take a sensor; the MBLJ upgrade opens the door to CMSG/DMSG/EMSG switches if needed. Remember the rear adjuster is a stop, not a lock, so add an external lock for held loads.
At 400mm stroke, the long rod is highly susceptible to bending from side loads; ensure rigid guidance to prevent premature seal failure.
Upgrade checklist
- ✓ Order the MBLJ32X400-75 (same bore/stroke/adjust)
- ✓ Same 325–400 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 MBLJ32X400-75 instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-75 FAQ
Yes, the MALJ32X400-75 is discontinued. The direct replacement is the MBLJ32X400-75, which matches the 32mm bore, 400mm stroke, 75mm adjuster, G1/8 port, and 82kgf max force. The MBLJ upgrades the construction to a riveted rolling-packed body and uses CMSG/DMSG/EMSG sensors if a magnet is added.
The usable stroke window is 325-400mm, trimmed by the 75mm rear adjuster. Note that this no-S SKU cannot accept a sensor, and the adjuster is a travel stop, not a load lock.
