This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X500-40, 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 MALJ32X500-40
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-40 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 460 to 500 mm. This model is discontinued — the direct replacement is the MBLJ32X500-40.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-40
The AirTAC MALJ32X500-40 is a discontinued double-acting double-rod mini cylinder with a rear adjustable stop. The 40 mm adjust code lets you trim the end position, creating a usable stroke window of 460-500 mm without external stops.
The direct replacement is the MBLJ32X500-40, matching the 32 mm bore, 500 mm stroke, G1/8 port and 40 mm adjust code. Upgrading brings a riveted rolling-packed body instead of the original threaded covers. This non-magnet SKU cannot accept a position sensor, whereas an MBLJ-S upgrade uses modern CMSG/DMSG/EMSG switches instead of the legacy CS1-M/DS1-M.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-40 Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-40 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X500-40 |
| Bore size | Ø32 mm |
| Stroke | 500 mm |
| Adjustable window | 460 – 500 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 MBLJ32X500-40 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 MBLJ32X500-40 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-40 Is Used
PCB Conveyor Diverter
Dial in the 460-500 mm extension to push populated PCB panels into a testing lane without adding external physical stop blocks on the machine frame.
Textile Loom Take-Up
Adjust the end-of-stroke position on the fly to maintain consistent fabric tension across a 500 mm travel, avoiding the need to swap out the entire cylinder.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-40 with MBLJ32X500-40
Replace this MALJ32X500-40 directly with the MBLJ32X500-40, confirming the 32 mm bore, 500 mm stroke, 40 mm adjust code, PT G1/8 port, M10x1.25 rod thread and FA/LB mounting (no back cover or SDB). Remember the adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air, relying only on a fixed rubber bumper to soften impact. At 500 mm stroke, rod-bending and side-load risks are high—maintain precise guide alignment to prevent stick-slip and premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ32X500-40 (same bore/stroke/adjust)
- ✓ Same 460–500 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 MBLJ32X500-40 instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-40 FAQ
Yes, the MALJ32X500-40 is discontinued. The direct replacement is the MBLJ32X500-40, which matches the 32 mm bore, 500 mm stroke, 40 mm adjust code, force, G1/8 port and mounting. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if you add an -S magnet.
The bore is 32 mm with a 460-500 mm usable stroke window (500 mm stroke minus the 40 mm adjust code). The adjuster is a travel stop, not a lock, and this non-S SKU cannot take a position sensor.
