This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X400-20, 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 MALJ32X400-20
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-20 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 380 to 400 mm. This model is discontinued — the direct replacement is the MBLJ32X400-20.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-20
The AirTAC MALJ32X400-20 is a discontinued adjustable-stroke, double-acting double-rod cylinder. It provides a usable travel window of 380-400 mm by using the 20 mm rear adjuster screw to trim the end position. The direct replacement is the MBLJ32X400-20, matching the bore, stroke, and G1/8 port.
This unit has a fixed rubber bumper, meaning the adjustable stroke sets the end position but is not an adjustable cushion. The adjuster is a travel stop, not a lock, so it will not hold a load without live air. Because this SKU lacks an -S magnet, it cannot accept a position sensor. Upgrading to the MBLJ replaces the older threaded covers with 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 MBLJ32X400-20 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 MBLJ32X400-20 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-20 Is Used
Pallet wrapper film carriage
Trims the end position to precisely engage the film clamp on varying pallet widths, preventing rod side-load on the long 400 mm stroke.
Textile loom beam loading
Fine-tunes the rear stop to seat heavy fabric beams into brackets, relying on the fixed rubber bumper to soften the end impact.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-20 with MBLJ32X400-20
To replace this MALJ32X400-20, order the MBLJ32X400-20. Confirm the 32 mm bore, 400 mm stroke, 20 mm adjust code, G1/8 port, and PT thread. Mounting is Basic, FA, or LB only (no back cover or SDB). This SKU has no magnet, so no sensor is used; if you ever need one, the MBLJ uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. The adjuster is a stop, not a lock.
At 400 mm stroke, the Ø12 mm rod is vulnerable to side-load bending; keep the load strictly axial to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ32X400-20 (same bore/stroke/adjust)
- ✓ Same 380–400 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 MBLJ32X400-20 instead of this discontinued model.
