This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X70-10S, 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 MALJ25X70-10S

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X70-10S
The AirTAC MALJ25X70-10S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. It has a 25 mm bore, a 70 mm stroke, and a -10 adjust code, giving a usable end-position window of 60-70 mm. The direct replacement is the MBLJ25X70-10S, which matches the bore, stroke, G1/8 port, and FA/LB mounting.
This SKU includes the -S magnet for position sensing. The original MALJ works with CS1-M or DS1-M switches, while the modern MBLJ replacement uses CMSG, DMSG, or EMSG sensors. The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. The cylinder uses a fixed rubber bumper and threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body.

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 MBLJ25X70-10S 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 MBLJ25X70-10S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X70-10S Is Used
Label Applicator Tamp
Fine-tune the tamp head reach within its 10 mm window to press labels onto recessed pouches without bending the 10 mm rod.
Wire Crimp Stop
Set a precise rear end position for a wire crimper, ensuring the 206 N pull retracts the crimp anvil cleanly without bottoming out.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X70-10S with MBLJ25X70-10S
To replace the MALJ25X70-10S, order the direct replacement MBLJ25X70-10S. Confirm the 25 mm bore, 70 mm stroke, -10 adjust code, PT G1/8 port, and FA/LB mounting (there is no back cover or SDB option). Remember the rear adjuster is a travel stop, not a lock, so add an external lock for held loads. The -S magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG on the MBLJ.
Upgrade checklist
- ✓ Order the MBLJ25X70-10S (same bore/stroke/adjust)
- ✓ Same 60–70 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 MBLJ25X70-10S instead of this discontinued model.
