This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X90-50-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).

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X90-50-S
The AirTAC MALJ25X90-50-S is a discontinued double-acting mini cylinder with a 50 mm rear travel stopper, yielding a usable extension window of 40-90 mm. The direct replacement is the MBLJ25X90-50-S.
This 25 mm bore unit uses a G1/8 port and a Ø10 mm hard-chrome rod. The rear adjuster sets the end position but does not hold the load without live air. The original threaded covers and CS1-M / DS1-M magnet switches are upgraded on the MBLJ to a riveted body and CMSG / DMSG / EMSG sensors.

| Replacement | MBLJ25X90-50-S |
| Bore size | Ø25 mm |
| Stroke | 90 mm |
| Adjustable window | 40 – 90 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |

| 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 MBLJ25X90-50-S carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 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 MBLJ25X90-50-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X90-50-S Is Used
Carton Flap Folder
Fine-tune the folding arm reach on a packaging line; the 50 mm rear stopper lets you adjust the 90 mm stroke to match varying box widths without swapping hardware.

Control the imprint depth on an ink coders. The fixed rubber bumper softens the impact, while the CS1-M / DS1-M magnet confirms the retracted position.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X90-50-S with MBLJ25X90-50-S
To replace this MALJ25X90-50-S, specify the MBLJ25X90-50-S to keep the 40-90 mm window, G1/8 port, and PT thread. Mounting is Basic, FA, or LB only; there is no back-cover or SDB option. Remember the adjuster is a travel stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ25X90-50-S (same bore/stroke/adjust)
- ✓ Same 40–90 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 MBLJ25X90-50-S instead of this discontinued model.
