This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X90-20, 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).

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-20
The AirTAC MALJ32X90-20 is a discontinued double-acting mini cylinder with a 20 mm rear adjustable stroke stopper. The 20 mm adjuster trims the end position, giving a usable stroke window of 70-90 mm. The direct replacement is the MBLJ32X90-20, matching the 32 mm bore, 90 mm stroke, G1/8 port, and force ratings.
This SKU lacks a -S magnet, so it cannot accept a position sensor. The rear adjuster sets travel but is a stop, not a lock; it will not hold a load without live air. The MALJ uses a fixed rubber bumper and threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body. If you need position sensing, the MBLJ uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M family.

| Bore size | Ø32 mm |
| Stroke | 90 mm |
| Adjustable window | 70 – 90 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |

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 MBLJ32X90-20 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 MBLJ32X90-20 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-20 Is Used
Carton flap folding arm
Adjusts the rear stop to time the exact 90 mm travel needed to tuck packaging flaps on a carton erecting machine, preventing tearing by fine-tuning the end position without moving the bracket.
Aluminum profile end-tap
Provides reliable 346 N pull force to retract a tapping head from an aluminum extrusion, using the fixed rubber bumper to absorb the repetitive shock of the 32 mm bore at high cycle rates.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-20 with MBLJ32X90-20
To replace the MALJ32X90-20, order the exact direct replacement MBLJ32X90-20. Confirm your 32 mm bore, 90 mm stroke, 20 mm adjust code, G1/8 port, and PT thread form. Mounting is Basic, FA, or LB only; there is no back cover or SDB option. Since this SKU lacks the -S magnet, it cannot take a sensor. Remember the adjuster is a travel stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ32X90-20 (same bore/stroke/adjust)
- ✓ Same 70–90 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 MBLJ32X90-20 instead of this discontinued model.
