This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X350-10-S, 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 MALJ20 Adjustable Mini Cylinder MALJ20X350-10-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-10-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 340 to 350 mm. This model is discontinued — the direct replacement is the MBLJ20X350-10-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-10-S
The AirTAC MALJ20X350-10-S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke. The -10 code lets you trim up to 10 mm at the rear, giving a usable window of 340-350 mm. Because the 350 mm stroke exceeds the 300 mm standard, it is a made-to-order part. The direct replacement is the MBLJ20X350-10-S.
This SKU includes a magnet (-S) for position sensing. The older MALJ uses CS1-M or DS1-M switches, while the MBLJ upgrade moves to CMSG, DMSG or EMSG sensors. The MALJ features threaded covers, whereas the MBLJ uses a riveted rolling-packed body. The rear adjuster functions strictly as a travel stop to fine-tune depth without external bolts, but it will not hold a load without live air. End impact is softened by a fixed rubber bumper, not an adjustable air cushion.

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ20X350-10-S |
| Bore size | Ø20 mm |
| Stroke | 350 mm |
| Adjustable window | 340 – 350 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |

| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 300 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 MBLJ20X350-10-S carries the same ratings.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 132 N | 132 N |
| 0.7 MPa | 185 N | — |
| Max (@1.0 MPa) | 27 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 MBLJ20X350-10-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-10-S Is Used
PCB Router Z-Axis Depth Setter
Dial in the exact 340-350 mm plunge depth on a PCB depaneling router.
Textile Loom Thread Guide
Position a thread guide arm deep into a weaving loom. The made-to-order 350 mm stroke reaches across the gantry, and the 10 mm adjuster absorbs frame tolerance variations without requiring custom spacers.
Foam Cutting Wire Tensioner
Actuate a tensioning gate on a hot-wire foam cutting machine. The fixed rubber bumper softens the end impact to protect the delicate 8 mm rod, while the -S magnet confirms wire position via CS1-M switches.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-10-S with MBLJ20X350-10-S
To replace this MALJ20X350-10-S with the MBLJ20X350-10-S, confirm the 20 mm bore, 350 mm stroke, 10 mm adjust code, G1/8 port, PT thread, and FA or LB mounting (no back cover or SDB allowed). Remember the adjuster is a stop, not a lock; you need an external lock for held loads. If you need to step down, the 20 mm bore is the smallest available, so no smaller neighbour exists. At 350 mm, the 8 mm rod is highly susceptible to side-load bending; ensure rigid guidance to prevent premature seal failure.
Upgrade checklist
- ✓ Order the MBLJ20X350-10-S (same bore/stroke/adjust)
- ✓ Same 340–350 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 MBLJ20X350-10-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X350-10-S FAQ
Yes, the MALJ20X350-10-S is discontinued. The direct replacement is the MBLJ20X350-10-S, which matches the 20 mm bore, 350 mm stroke, 10 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The -10 adjuster is a travel stop that lets you shorten the end position by up to 10 mm, creating a 340-350 mm usable window. It does not hold the load without live air.
