This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X175-20S, 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-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-20-S 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-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-20-S
The AirTAC MALJ32X175-20-S is a discontinued adjustable-stroke, double-acting double-rod mini cylinder. It features a 32mm bore, 175mm stroke, and a rear travel stopper that trims up to 20mm, yielding a usable end-position window of 155-175mm.
The direct replacement is the MBLJ32X175-20-S, matching the bore, stroke, adjust code, G1/8 port, and force. Upgrading swaps the threaded covers for a riveted rolling-packed body, and the -S magnet switches from the older CS1-M/DS1-M switches to the current CMSG/DMSG/EMSG sensor family. Remember, the adjuster sets the end position but does not hold load without live air.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-20-S Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-20-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X175-20-S |
| 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) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| 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-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 MBLJ32X175-20-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-20-S Is Used
Carton Flap Folder
Fine-tune the folding arm end position by up to 20mm on a packaging line, accommodating varying corrugated cardboard thicknesses without changing the cylinder mounting.
Small Press Tamp Pin
Set a precise 155mm retracted depth for a label tamper pin on an automated press, relying on the fixed rubber bumper to absorb the 563N impact at 0.7MPa.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-20-S with MBLJ32X175-20-S
To replace the MALJ32X175-20-S, install the exact direct replacement MBLJ32X175-20-S. Confirm the 32mm bore, 175mm stroke, 20mm adjust code, PT G1/8 port, M10x1.25 rod-end thread, and FA/LB mounting (there is no back-cover or SDB option). The -S magnet requires new CMSG/DMSG/EMSG sensors, as the old CS1-M/DS1-M switches will not fit the MBLJ. The rear adjuster is a travel stop, not a lock; add an external lock if you need to hold a load without air.
At 175mm stroke, keep the rod guided to prevent side-load bending, as the 12mm rod is fully extended.
Upgrade checklist
- ✓ Order the MBLJ32X175-20-S (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-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X175-20-S FAQ
Yes, the MALJ32X175-20-S is discontinued. The direct replacement is the MBLJ32X175-20-S, which matches the 32mm bore, 175mm stroke, 20mm adjust code, G1/8 port, and force. The MBLJ upgrades the body to a riveted rolling-packed design and requires CMSG/DMSG/EMSG sensors for the -S magnet, replacing the older CS1-M/DS1-M switches.
The 20mm rear adjuster provides a usable stroke window of 155-175mm. It is a travel stop, not a lock, so it will not hold a load without live air.
