This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X150-100S, 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 MALJ25X150-100-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X150-100-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 50 to 150 mm. This model is discontinued — the direct replacement is the MBLJ25X150-100-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-100-S
The AirTAC MALJ25X150-100-S is a discontinued adjustable-stroke mini cylinder. The direct replacement is the MBLJ25X150-100-S, matching the 25mm bore, 150mm stroke, and 100mm adjustment. This SKU provides a usable stroke window of 50-150mm, letting you dial in the exact reach without external stops.
The rear adjuster acts as a travel stop to set the end position; it is not a lock and will not hold a load without live air. This MALJ uses a -S magnet compatible with older CS1-M/DS1-M reed switches, while the MBLJ replacement upgrades to CMSG/DMSG/EMSG sensors. The original features threaded covers and a fixed rubber bumper, whereas the MBLJ uses a riveted rolling-packed body. Porting is G1/8 with a 10mm rod and M10x1.25 rod-end thread.

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 MBLJ25X150-100-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 MBLJ25X150-100-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-100-S Is Used
Leather Press Creaser
Adjusts the 25mm bore stroke to vary crease depth on varying leather thicknesses, relying on the fixed rubber bumper to soften the end impact.
Pneumatic Tube Cutter
Trims the 150mm stroke down to 50mm for fast, short cuts on thin tubing, using the 206N pull force to retract the blade without repositioning the cylinder.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-100-S with MBLJ25X150-100-S
To replace this MALJ25X150-100-S with the MBLJ25X150-100-S, confirm the 25mm bore, 150mm stroke, 100mm adjust code, G1/8 port, and PT thread. Mounting is FA or LB only (no back cover or SDB). The -S magnet means a sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. The rear adjuster is a travel stop, not a lock; add an external lock for held loads.
At 150mm stroke, watch for rod-bending under side loads; keep the load guided to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ25X150-100-S (same bore/stroke/adjust)
- ✓ Same 50–150 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 MBLJ25X150-100-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-100-S FAQ
Yes, the AirTAC MALJ25X150-100-S is discontinued. The direct replacement is the MBLJ25X150-100-S, which matches the 25mm bore, 150mm stroke, 100mm adjuster, G1/8 port, and force ratings. The MBLJ upgrades the body to a riveted rolling-packed design and switches sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 100mm adjust code allows trimming the 150mm stroke back to a 50mm usable window. The rear adjuster is a travel stop, not a load lock.
