This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X500-30, 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 MALJ32X500-30
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-30 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 470 to 500 mm. This model is discontinued — the direct replacement is the MBLJ32X500-30.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-30
The AirTAC MALJ32X500-30 is a discontinued adjustable-stroke, double-acting double-rod mini cylinder. The 30 mm rear adjuster creates a usable stroke window of 470-500 mm. The direct replacement is the MBLJ32X500-30, matching the 32 mm bore, 500 mm stroke, G1/8 port, and force ratings exactly.
This SKU lacks a magnet (-S), so it cannot accept a position sensor. The original MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body. Remember the adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air pressure.

| 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 MBLJ32X500-30 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 MBLJ32X500-30 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-30 Is Used
Automotive Wire Harness Jigs
Fine-tune the crimping head reach on long harness routing machines, ensuring the 500 mm stroke terminates exactly where the wire gauge demands without external stops.
Wood Door Pressing Frames
Adjust the rear stopper to 480 mm to control platen depth on edge-banding presses, using the 346 N pull force to maintain consistent tension across the workpiece.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-30 with MBLJ32X500-30
To replace this MALJ32X500-30, order the direct replacement MBLJ32X500-30. Confirm the 32 mm bore, 500 mm stroke, 30 mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB allowed). Because this SKU has no -S magnet, it cannot take a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you add one. The adjuster is a stop, not a lock. With a 500 mm stroke, rod side-load and bending are critical; ensure rigid guidance to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ32X500-30 (same bore/stroke/adjust)
- ✓ Same 470–500 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 MBLJ32X500-30 instead of this discontinued model.
