This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X50-30-S, 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 MALJ32X50-30-S

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-30-S
The AirTAC MALJ32X50-30-S is a discontinued double-acting, double-rod mini cylinder with a 32 mm bore and 50 mm stroke. It provides a usable travel window of 20-50 mm by trimming up to 30 mm at the rear stopper. The direct replacement is the MBLJ32X50-30-S, matching the bore, stroke, adjust code, G1/8 port, and mounting.
This -S SKU includes a magnet for CS1-M or DS1-M switches; the MBLJ replacement upgrades to CMSG/DMSG/EMSG sensors and a riveted rolling-packed body instead of the MAL threaded covers. The fixed rubber bumper softens end impact, but the adjuster is a travel stop, not a lock. It cannot hold a load without live air.

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 MBLJ32X50-30-S 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 MBLJ32X50-30-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-30-S Is Used
Aluminum Extrusion Notching
Fine-tune the retract distance on an extrusion notching station, allowing operators to shift the 30 mm adjuster for different profile lengths instead of repositioning hard stops.
Carton Flap Folding
Adjust the end position on a packaging line flap folder to accommodate varying box heights, relying on the fixed rubber bumper to absorb the impact of repetitive folding strokes.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-30-S with MBLJ32X50-30-S
To replace the MALJ32X50-30-S with the MBLJ32X50-30-S, confirm the 32 mm bore, 50 mm stroke, 30 mm adjust code, PT G1/8 port, and M10x1.25 rod thread. Mounting is Basic, FA, or LB only, as there is no back cover or SDB option. Remember the rear adjuster sets the end position but does not lock the load. The -S magnet changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG.
Upgrade checklist
- ✓ Order the MBLJ32X50-30-S (same bore/stroke/adjust)
- ✓ Same 20–50 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 MBLJ32X50-30-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-30-S FAQ
Yes, the MALJ32X50-30-S is discontinued. The direct replacement is the MBLJ32X50-30-S, which matches the 32 mm bore, 50 mm stroke, 30 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 30 mm adjuster creates a usable stroke window of 20-50 mm. The rear screw is a travel stop, not a lock, so it will not hold a load without live air.
