This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X250-20S, 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 MALJ32X250-20-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X250-20-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 230 to 250 mm. This model is discontinued — the direct replacement is the MBLJ32X250-20-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X250-20-S
The AirTAC MALJ32X250-20-S is a discontinued double-acting mini cylinder with a 32mm bore and 250mm stroke. The -20 code lets you dial out up to 20mm of rear travel, creating a usable 230-250mm end-position window. The direct replacement is the MBLJ32X250-20-S, matching the bore, stroke, port, and force.
This -S variant carries a magnet for CS1-M or DS1-M reed switches; the MBLJ upgrade shifts to CMSG/DMSG/EMSG sensors. The MALJ uses threaded covers, whereas the MBLJ features a riveted rolling-packed body. A fixed rubber bumper softens end impact, but the rear adjuster is a travel stop, not a lock—it cannot hold a load without live air.

| Bore size | Ø32 mm |
| Stroke | 250 mm |
| Adjustable window | 230 – 250 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 MBLJ32X250-20-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 MBLJ32X250-20-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X250-20-S Is Used
Aluminum Extrusion Notching
Fine-tunes the 20mm rear travel window on a profile notching station, allowing operators to hit varying notch depths without swapping mechanical hard stops.
Carton Flap Folding
Adjusts the folding arm end-position on a packaging line to accommodate different carton heights, relying on the fixed rubber bumper to absorb the 563N impact at 0.7MPa.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X250-20-S with MBLJ32X250-20-S
To replace this MALJ32X250-20-S, order the MBLJ32X250-20-S. Confirm the 32mm bore, 250mm stroke, 20mm adjust code, G1/8 PT port, and M10x1.25 rod thread. Mounting is Basic, FA, or LB only (no back cover or SDB). With a 250mm stroke, minimize side-load to prevent rod bending—guide the load externally. Remember the adjuster sets position but does not lock the load.
Upgrade checklist
- ✓ Order the MBLJ32X250-20-S (same bore/stroke/adjust)
- ✓ Same 230–250 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 MBLJ32X250-20-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X250-20-S FAQ
Yes, the MALJ32X250-20-S is discontinued. The direct replacement is the MBLJ32X250-20-S, which matches the 32mm bore, 250mm stroke, 20mm adjust code, and G1/8 port. You will need to upgrade your sensors from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
The -20 code means you can trim up to 20mm at the rear, giving a usable stroke window of 230-250mm. The adjuster is a travel stop, not a lock, and cannot hold a load without live air.
