This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X70-20, 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 MALJ32X70-20
The AirTAC MALJ32X70-20 is a discontinued adjustable-stroke mini cylinder. It is double-acting with a 32mm bore and 70mm stroke. The rear adjuster trims up to 20mm, creating a usable end-position window of 50-70mm. The direct replacement is the MBLJ32X70-20, matching the bore, stroke, force, G1/8 port, and mounting.
This SKU lacks a magnet (-S), so it 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 fixed rubber bumper softens impact, while the carbon-steel rod has a 20 um hard chrome plating to resist wear. Upgrading to the MBLJ moves from threaded covers to a riveted rolling-packed body.

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 MBLJ32X70-20 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 MBLJ32X70-20 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-20 Is Used
Carton Flap Folder
Sets a 60mm reach to fold corrugated box flaps, relying on the fixed rubber bumper to absorb the 346N pull impact.
Pneumatic Press Pin Stop
Trims the rear 20mm stop to set exact seating depth for dowel pins, preventing over-travel on the return stroke.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-20 with MBLJ32X70-20
To replace the MALJ32X70-20, order the MBLJ32X70-20. Confirm the 32mm bore, 70mm stroke, 20mm adjust code, PT G1/8 port, M10x1.25 rod thread, and FA/LB mounting (no back cover or SDB). Since this SKU lacks the -S magnet, it cannot accept a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you add a magnet. Remember the adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ32X70-20 (same bore/stroke/adjust)
- ✓ Same 50–70 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 MBLJ32X70-20 instead of this discontinued model.
