This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X80-30S, 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 MALJ25 Adjustable Mini Air Cylinder MALJ25X80-30-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X80-30-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 50 to 80 mm. This model is discontinued — the direct replacement is the MBLJ25X80-30-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-30-S
The AirTAC MALJ25X80-30-S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. It provides a usable travel window of 50-80 mm by trimming up to 30 mm at the rear screw.
The MBLJ upgrade uses a riveted rolling-packed body instead of the original threaded covers. Your -S magnet switches from the older CS1-M / DS1-M to the CMSG / DMSG / EMSG family. The adjuster is a travel stop, not a lock, and the fixed rubber bumper softens end impact without holding load pneumatically.

| Replacement | MBLJ25X80-30-S |
| Bore size | Ø25 mm |
| Stroke | 80 mm |
| Adjustable window | 50 – 80 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |

| 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 MBLJ25X80-30-S carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |

| 0.7 MPa | 289 N | — |
| Max (@1.0 MPa) | 42 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 MBLJ25X80-30-S matches these values.

Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-30-S with MBLJ25X80-30-S
Replace this MALJ with the MBLJ25X80-30-S, confirming the 25 mm bore, 80 mm stroke, 30 mm adjust code, G1/8 port, and M10x1.25 rod-end thread. Mounting is FA or LB only, with no back cover or SDB. The rear adjuster sets the end position but does not hold load without live air. For any stroke over 300 mm, add external guides to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ25X80-30-S (same bore/stroke/adjust)
- ✓ Same 50–80 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 MBLJ25X80-30-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-30-S FAQ
Yes, the MALJ25X80-30-S is discontinued. The direct replacement is the MBLJ25X80-30-S, matching the 25 mm bore, 80 mm stroke, 30 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and shifts the -S magnet compatibility from CS1-M / DS1-M to CMSG / DMSG / EMSG switches.
The 30 mm adjust code lets you trim the rear end position, creating a usable stroke window of 50-80 mm. The adjuster is a travel stop, not a lock.
