This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X150-10S, 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 MALJ25 Adjustable Mini Air Cylinder MALJ25X150-10-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X150-10-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 140 to 150 mm. This model is discontinued — the direct replacement is the MBLJ25X150-10-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-10-S
The AirTAC MALJ25X150-10-S is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. A rear stopper screw lets you trim the end position by up to 10 mm, creating a usable stroke window of 140-150 mm. The direct replacement is the MBLJ25X150-10-S, matching the bore, stroke, adjust code, and G1/8 port.
This SKU includes a magnet (-S) for legacy CS1-M or DS1-M reed switches; the MBLJ upgrade shifts to CMSG/DMSG/EMSG sensors. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ features a riveted rolling-packed body. Remember that the rear adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air pressure.

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 MBLJ25X150-10-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 MBLJ25X150-10-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-10-S Is Used
PCB Router Z-Axis Stop
Dial the 140-150 mm end window on this 245 N cylinder to set the exact cutting depth for a PCB depaneling router without adding external physical stops.
Dispenser Valve Shutoff
Trim the 10 mm rear stroke to precisely time the pinch on a fluid dispenser valve, ensuring accurate shot volumes using the 206 N pull force.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-10-S with MBLJ25X150-10-S
To replace the MALJ25X150-10-S, order the MBLJ25X150-10-S. Confirm the 25 mm bore, 150 mm stroke, 10 mm adjust code, PT G1/8 port, and M10x1.25 rod-end thread. Mounting is limited to FA or LB; there is no back cover or SDB option. Note that the rear adjuster is a stop, not a lock, so add an external lock for held loads. At 150 mm stroke, minimize side-load to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ25X150-10-S (same bore/stroke/adjust)
- ✓ Same 140–150 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 MBLJ25X150-10-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-10-S FAQ
Yes, the MALJ25X150-10-S is discontinued. The direct replacement is the MBLJ25X150-10-S, which matches the 25 mm bore, 150 mm stroke, 10 mm adjust code, and G1/8 port. The MBLJ upgrade uses a riveted rolling-packed body instead of threaded covers, and its magnet works with CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M sensors.
The 10 mm adjust code is a rear travel stop that lets you shorten the end position, creating a usable stroke window of 140-150 mm. It is a stop, not a lock, and does not hold load without live air.
