This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X400-30S, 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 MALJ32X400-30-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-30-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 370 to 400 mm. This model is discontinued — the direct replacement is the MBLJ32X400-30-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-30-S
The AirTAC MALJ32X400-30-S is a discontinued adjustable-stroke, double-acting double-rod mini cylinder. It features a 32mm bore, 400mm stroke, and a rear adjuster that trims up to 30mm, yielding a usable end-position window of 370-400mm. The direct replacement is the MBLJ32X400-30-S, matching the bore, stroke, adjust code, G1/8 port, and mounting.
The rear adjuster functions strictly as a travel stop to fine-tune reach without external shims; it does not hold load without live air. This SKU includes a -S magnet for position sensing. The older MALJ uses CS1-M/DS1-M switches and threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. Impact is absorbed by a fixed rubber bumper, not an adjustable air cushion.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-30-S Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-30-S |

| Bore size | Ø32 mm |
| Stroke | 400 mm |
| Adjustable window | 370 – 400 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

| 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 MBLJ32X400-30-S 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 MBLJ32X400-30-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-30-S Is Used
Long-Travel Forming Pin
Dials in the end position on a 400mm sheet-metal forming pin, absorbing impact with the fixed rubber bumper while avoiding external stop hardware.
Carton Flap Folder
Adjusts reach on a packaging line carton folder, tuning the 30mm window to compensate for varying corrugated cardboard thicknesses without changing fixtures.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X400-30-S with MBLJ32X400-30-S
To replace this MALJ32X400-30-S, order the direct replacement MBLJ32X400-30-S. Confirm the 32mm bore, 400mm stroke, 30mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). The -S magnet means a sensor family change: MALJ uses CS1-M/DS1-M, while MBLJ uses CMSG/DMSG/EMSG. The adjuster is a stop, not a lock; use an external lock for held loads. At 400mm stroke, rod-bending and side-load risks are high—ensure guide loads to prevent rod damage.
Upgrade checklist
- ✓ Order the MBLJ32X400-30-S (same bore/stroke/adjust)
- ✓ Same 370–400 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 MBLJ32X400-30-S instead of this discontinued model.
