This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X175-20, 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).
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-20
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-20 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 155 to 175 mm. This model is discontinued — the direct replacement is the MBLJ32X175-20.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-20
The AirTAC MALJ32X175-20 is a discontinued 32mm bore, double-acting adjustable-stroke mini cylinder. A rear stopper lets you trim up to 20mm, creating a usable end-position window of 155-175mm. The direct replacement is the MBLJ32X175-20.
This SKU lacks the -S magnet, so it cannot accept a position sensor. The original threaded covers are upgraded to a riveted rolling-packed body on the MBLJ. The fixed rubber bumper absorbs end impact, but the adjuster is a travel stop, not a lock; it will not hold a load without live air pressure.

| Bore size | Ø32 mm |
| Stroke | 175 mm |
| Adjustable window | 155 – 175 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

| 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 MBLJ32X175-20 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 MBLJ32X175-20 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-20 Is Used
PCB Router Depth Stop
Dials the final 155-175mm extension on a PCB depaneling router to match varying panel thicknesses without adding external physical stops.
Carton Flap Plow
Adjusts the stroke window on a packaging line plow to clear varying carton heights, using the fixed rubber bumper to soften the end impact.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-20 with MBLJ32X175-20
To replace the MALJ32X175-20, order the exact direct replacement MBLJ32X175-20. Confirm the 32mm bore, 175mm stroke, 20mm adjust code, G1/8 port, and PT thread. Mounting is FA or LB only (no back cover or SDB). Because this SKU has no -S magnet, it cannot take a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you need sensing.
At 175mm stroke, the 12mm rod is susceptible to bending under side loads; use rigid guidance to prevent premature seal failure. The adjuster sets end position but does not hold load without air.
Upgrade checklist
- ✓ Order the MBLJ32X175-20 (same bore/stroke/adjust)
- ✓ Same 155–175 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 MBLJ32X175-20 instead of this discontinued model.
