This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X25-10S, 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 MALJ20X25-10-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X25-10-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 15 to 25 mm. This model is discontinued — the direct replacement is the MBLJ20X25-10-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X25-10-S
The AirTAC MALJ20X25-10-S is a discontinued double-acting mini cylinder with a rear travel stopper. The direct replacement is the MBLJ20X25-10-S, matching the 20 mm bore, G1/8 port, and 8 mm rod.
This -S SKU uses a CS1-M / DS1-M magnet sensor, while the MBLJ replacement upgrades to CMSG / DMSG / EMSG switches. The original MALJ features threaded covers and a fixed rubber bumper; the newer MBLJ uses a riveted rolling-packed body. Remember, the rear adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure.

| Bore size | Ø20 mm |
| Stroke | 25 mm |
| Adjustable window | 15 – 25 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

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 MBLJ20X25-10-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 MBLJ20X25-10-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X25-10-S Is Used
PCB Depaneling Stop
Sets a precise 15-25 mm reach on a depaneling router to press carrier edges without stressing the scored PCB substrate.
Micro-Clamp Depth
Dials in the end position on a small pneumatic clamp holding 3 mm sheet metal, allowing 10 mm of travel tuning without shims.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X25-10-S with MBLJ20X25-10-S
To replace this MALJ20X25-10-S, order the exact direct replacement MBLJ20X25-10-S. Confirm the 20 mm bore, 25 mm stroke, 10 mm adjust code, G1/8 port, and M8x1.25 rod thread. Mounting is FA or LB only; there is no back cover or SDB option. The -S magnet means your old CS1-M / DS1-M sensors will need to swap to CMSG / DMSG / EMSG switches on the new riveted body.
The rear adjuster sets the end position but is not a mechanical lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ20X25-10-S (same bore/stroke/adjust)
- ✓ Same 15–25 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 MBLJ20X25-10-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X25-10-S FAQ
Yes, the MALJ20X25-10-S is discontinued. The direct replacement is the MBLJ20X25-10-S, which matches the 20 mm bore, 25 mm stroke, 10 mm adjust code, G1/8 port, and 8 mm rod. You will need to upgrade your sensors from the old CS1-M / DS1-M to the CMSG / DMSG / EMSG family.
The 10 mm adjust code creates a usable stroke window of 15-25 mm. The adjuster is a travel stop, not a lock, and impact is softened by a fixed rubber bumper.
