This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X90-50, 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 MALJ32X90-50
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-50 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 40 to 90 mm. This model is discontinued — the direct replacement is the MBLJ32X90-50.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-50
It provides a usable extension window of 40-90 mm by trimming up to 50 mm at the rear stopper. The direct replacement is the MBLJ32X90-50, matching the bore, stroke, adjuster code, and G1/8 port.
This mini cylinder uses a fixed rubber bumper, meaning the adjustable stroke sets the end position but does not provide an air cushion. The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. Upgrading to the MBLJ32X90-50 transitions you from threaded covers to a riveted rolling-packed body, and from the older CS1-M/DS1-M switches to the modern CMSG/DMSG/EMSG sensor family if a magnet is added.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-50 Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-50 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X90-50 |
| Bore size | Ø32 mm |
| Stroke | 90 mm |
| Adjustable window | 40 – 90 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| 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 MBLJ32X90-50 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 MBLJ32X90-50 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-50 Is Used
Carton Flap Folder
Adjust the rear stopper on a packaging line to fold varying corrugated carton flap heights, relying on the fixed rubber bumper to absorb the 0.5 MPa impact at the end of travel.
Aluminum Extrusion Gauge
Fine-tune the reach of a 32 mm rod inspection gauge to check cut lengths on an aluminum extrusion line, backing off the stroke by up to 50 mm without machining new mount plates.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-50 with MBLJ32X90-50
To replace the MALJ32X90-50, order the MBLJ32X90-50. Confirm the 32 mm bore, 90 mm stroke, 50 mm adjust code, G1/8 port, and PT thread form. Mounting is limited to FA or LB; there is no back-cover or SDB option. Remember the adjuster is a travel stop, not a lock, so an external lock is required for load holding without air.
Since this SKU has no -S magnet, it cannot take a sensor; the MBLJ replacement allows you to specify a magnet for CMSG/DMSG/EMSG switches.
Upgrade checklist
- ✓ Order the MBLJ32X90-50 (same bore/stroke/adjust)
- ✓ Same 40–90 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 MBLJ32X90-50 instead of this discontinued model.
