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

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-50-S
The AirTAC MALJ25X150-50-S is a discontinued double-acting double-rod mini cylinder with a rear adjustable stroke stopper. It provides a usable extension window of 100-150 mm by trimming up to 50 mm at the rear screw. The direct replacement is the MBLJ25X150-50-S, matching the bore, stroke, force, G1/8 port, and mounting.
This -S SKU includes a magnet for position sensing. The legacy MAL uses CS1-M or DS1-M reed switches, whereas the MBLJ upgrade takes CMSG, DMSG, or EMSG sensors. The MAL features threaded covers and a fixed rubber bumper, while the MBLJ uses a riveted rolling-packed body. 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 MBLJ25X150-50-S carries the same ratings.
Theoretical Output Force (Ø25mm)

| 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 MBLJ25X150-50-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-50-S Is Used
Carton Flap Folder
Fine-tunes the folding arm end position on packaging lines to accommodate different box heights, preventing crushing with the fixed rubber bumper.
Textile Loom Tensioner
Sets precise material take-up reach. The rear stopper holds the set position, while the CS1-M sensor confirms the adjusted stroke end.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-50-S with MBLJ25X150-50-S
To replace this MALJ25X150-50-S, order the MBLJ25X150-50-S. Confirm the 25 mm bore, 150 mm stroke, 50 mm adjust code, G1/8 PT port, and M10x1.25 rod thread. Mounting is FA or LB only; there is no back cover or SDB option. Remember the adjuster is a stop, not a lock. At 150 mm stroke, mind rod side-load to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ25X150-50-S (same bore/stroke/adjust)
- ✓ Same 100–150 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 MBLJ25X150-50-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-50-S FAQ
Yes, the MALJ25X150-50-S is discontinued. The direct replacement is the MBLJ25X150-50-S, which matches the 25 mm bore, 150 mm stroke, 50 mm adjust code, and G1/8 port. You will need to upgrade your sensors from the old CS1-M/DS1-M to the CMSG/DMSG/EMSG family.
The usable stroke window is 100-150 mm. At 0.5 MPa it pushes 245 N and pulls 206 N. At 0.7 MPa it pushes 343 N. The maximum force is 50 kgf at 1.0 MPa. The rear adjuster is a travel stop, not a lock, and cannot hold a load without air.
