This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X250-20, 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 MALJ32X250-20
The AirTAC MALJ32X250-20 is a discontinued double-acting, double-rod mini cylinder featuring a rear adjustable stroke stopper. This 32 mm bore unit trims up to 20 mm at the rear, yielding a usable stroke window of 230-250 mm. The direct replacement is the MBLJ32X250-20, which matches the bore, stroke, force, and G1/8 port.
This SKU has no -S magnet and cannot take a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but holds no load without live air. The original MALJ uses threaded covers and the MBLJ upgrade shifts to a riveted rolling-packed body. A fixed rubber bumper absorbs end impact, meaning the adjustable stroke must not be confused with an adjustable cushion.

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 MBLJ32X250-20 carries the same ratings.
Theoretical Output Force (Ø32mm)

| 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 MBLJ32X250-20 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X250-20 Is Used
Carton Flap Folder
Fine-tune the folding arm reach on a continuous carton erector without adding external spacers, ensuring the 250 mm stroke hits the exact flap crease every cycle.
Pneumatic Rivet Press
Adjust the end position by up to 20 mm to control squeeze distance on an aluminum rivet press, letting the 346 N pull force set rivet heads without bottoming out hard.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X250-20 with MBLJ32X250-20
Replace this MALJ32X250-20 directly with the MBLJ32X250-20. Confirm the 32 mm bore, 250 mm stroke, 20 mm adjust code, G1/8 port, and PT thread. Mounting is limited to FA or LB; there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot accept a sensor; the MBLJ upgrade with a -S suffix uses the newer CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. The rear adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ32X250-20 (same bore/stroke/adjust)
- ✓ Same 230–250 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 MBLJ32X250-20 instead of this discontinued model.
