This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X175-50, 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 MALJ32X175-50

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-50
The AirTAC MALJ32X175-50 is a discontinued adjustable-stroke mini cylinder. It features a 32mm bore, a 175mm stroke, and a 50mm rear adjuster, giving a usable end-position window of 125-175mm. The direct replacement is the MBLJ32X175-50, matching the bore, stroke, force, G1/8 port, and mounting.
This SKU lacks a magnet (-S) and cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. The fixed rubber bumper softens end impact, but this is not an adjustable cushion. Upgrading to the MBLJ replaces the threaded covers with a riveted rolling-packed body.

| Bore size | Ø32 mm |
| Stroke | 175 mm |
| Adjustable window | 125 – 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 MBLJ32X175-50 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 MBLJ32X175-50 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-50 Is Used
Aluminum Profile Notching
Fine-tune the 50mm rear stopper on an extrusion notching station to alter the cut depth for different profile widths, relying on the fixed rubber bumper to absorb the 346N retract impact.
Packaging Flap Folder
Adjust the end position on a carton flap-folding arm to clear various box heights, using the G1/8 port flow to time the 175mm stroke precisely without adding external hard stops.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-50 with MBLJ32X175-50
To replace the MALJ32X175-50, order the MBLJ32X175-50. Confirm the 32mm bore, 175mm stroke, 50mm adjust code, G1/8 port, PT thread, and FA/LB mounting. This non-magnet SKU cannot take a sensor, but if you previously used a -S variant, note the switch from CS1-M/DS1-M to CMSG/DMSG/EMSG switches. The adjuster sets end position but is not a lock.
At 175mm stroke, minimize side-load to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ32X175-50 (same bore/stroke/adjust)
- ✓ Same 125–175 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 MBLJ32X175-50 instead of this discontinued model.
