This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X25-20, 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).

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-20
The AirTAC MALJ32X25-20 is a discontinued double-acting double-rod mini cylinder with a rear adjustable stroke stopper. The direct replacement is the MBLJ32X25-20, which matches the 32mm bore, 25mm stroke, G1/8 port and 20mm adjust code. This SKU lacks the -S magnet, so it cannot take a position sensor.
The 20mm adjust code lets you dial back the rear position, creating a usable stroke window of 5-25mm. The adjuster is a travel stop, not a lock. The original MALJ uses threaded covers and the MBLJ upgrade uses a riveted rolling-packed body.

| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-20 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X25-20 |
| Bore size | Ø32 mm |
| Stroke | 25 mm |
| Adjustable window | 5 – 25 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 MBLJ32X25-20 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 MBLJ32X25-20 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-20 Is Used
Bottle Capper Height Adjust
Fine-tune the downward reach on a benchtop screw capping station without adding external shims, using the 20mm rear stop to handle varied bottle neck heights.
Small Parts Forming Press
Crimp electrical terminals at a precise 5-25mm stroke endpoint, letting the fixed rubber bumper absorb the 346N pull impact without needing an air cushion.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-20 with MBLJ32X25-20
Replace this MALJ32X25-20 with the exact MBLJ32X25-20 direct. Confirm the 32mm bore, 25mm stroke, 20mm adjust code, G1/8 PT port, and FA or LB mounting (no back cover or SDB). Because this SKU lacks the -S magnet, it cannot hold a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you add a magnet. The adjuster sets the end position but does not hold load without live air.
Upgrade checklist
- ✓ Order the MBLJ32X25-20 (same bore/stroke/adjust)
- ✓ Same 5–25 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 MBLJ32X25-20 instead of this discontinued model.
