This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X70-30-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 MALJ32X70-30-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-30-S 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 40 to 70 mm. This model is discontinued — the direct replacement is the MBLJ32X70-30-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-30-S
The AirTAC MALJ32X70-30-S is a discontinued 32mm bore, double-acting double-rod mini cylinder with a rear adjustable stroke stopper. It trims up to 30mm at the rear, giving a usable end-position window of 40-70mm. The direct replacement is the MBLJ32X70-30-S, matching bore, stroke, force, and port.
The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. This MALJ has threaded covers and a -S magnet using older CS1-M/DS1-M switches, while the MBLJ upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. It uses a fixed rubber bumper, not an adjustable air cushion.

| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| 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 MBLJ32X70-30-S 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 MBLJ32X70-30-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-30-S Is Used
PCB Router Z-Axis
Dial the 40-70mm stroke window to set precise Z-axis plunge depth on a PCB routing spindle without recalculating CNC end stops.
Carton Flap Folder
Adjust the end position on the fly to fold varying carton sizes, relying on the fixed rubber bumper to soften the end impact.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-30-S with MBLJ32X70-30-S
To replace this MALJ32X70-30-S, order the exact direct replacement MBLJ32X70-30-S. Confirm the 32mm bore, 70mm stroke, 30mm adjust code, G1/8 port, and PT thread. Mounting is FA or LB only; there is no back-cover or SDB option. The -S magnet changes sensor families from CS1-M/DS1-M to CMSG/DMSG/EMSG. Remember the adjuster is a stop, not a lock.
This 70mm stroke is well within the 500mm maximum for a 32mm bore, avoiding rod-bending side-load issues.
Upgrade checklist
- ✓ Order the MBLJ32X70-30-S (same bore/stroke/adjust)
- ✓ Same 40–70 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 MBLJ32X70-30-S instead of this discontinued model.
