This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X500-50, 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).

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-50
The AirTAC MALJ32X500-50 is a discontinued double-acting adjustable-stroke mini cylinder. The 50 mm rear adjuster sets a usable end-position window of 450-500 mm. The direct replacement is the MBLJ32X500-50.
This SKU lacks the -S magnet and cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body.

| 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 MBLJ32X500-50 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 MBLJ32X500-50 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-50 Is Used
Conveyor Divert Arm
Fine-tune the actuation reach on a parcel sorting conveyor, trimming the end position by up to 50 mm to accommodate varying box widths.
Sheet Metal Stack Alignment
Adjust the rear stop to set exact contact depth on a 500 mm press feed, using the fixed rubber bumper to soften the impact of the 12 mm rod.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-50 with MBLJ32X500-50
Replace this MALJ32X500-50 with the exact MBLJ32X500-50 direct. Confirm the 32 mm bore, 500 mm stroke, 50 mm adjust code, G1/8 port, PT threads, and FA/LB mounting (no back cover or SDB). Since this SKU lacks the -S magnet, no sensor is used; if you need sensing, the MBLJ uses CMSG/DMSG/EMSG switches. The adjuster is a stop, not a lock.
At 500 mm stroke, side-load and rod-bending risks are high; ensure rigid guidance to prevent seal damage.
Upgrade checklist
- ✓ Order the MBLJ32X500-50 (same bore/stroke/adjust)
- ✓ Same 450–500 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 MBLJ32X500-50 instead of this discontinued model.
