This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X175-10S, 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 MALJ25X175-10-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X175-10-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 165 to 175 mm. This model is discontinued — the direct replacement is the MBLJ25X175-10-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-10-S
The AirTAC MALJ25X175-10-S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stop. It provides a usable stroke window of 165-175 mm, letting you dial in the exact end position without external stops. The direct replacement is the MBLJ25X175-10-S, matching the 25 mm bore, 175 mm stroke, G1/8 port, and 10 mm adjust code.
This -S variant includes a magnet for position sensing. During the upgrade to the MBLJ, the sensor family changes from the older CS1-M/DS1-M switches to CMSG/DMSG/EMSG. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ features a riveted rolling-packed body. Remember the rear adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure.

| 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 MBLJ25X175-10-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 MBLJ25X175-10-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-10-S Is Used
Dispenser Valve Depth
Dials in the exact 165 mm downward reach for a pneumatic adhesive dispenser valve, ensuring the nozzle clears tall connectors before the fixed rubber bumper makes contact.
Leather Press Creaser
Provides a 170 mm stroke window on an industrial leather creasing press, using the 206 N pull force to retract the heated brass tip while accommodating varying hide thicknesses.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-10-S with MBLJ25X175-10-S
To replace this MALJ25X175-10-S, order the exact MBLJ25X175-10-S direct. Confirm the 25 mm bore, 175 mm stroke, 10 mm adjust code, PT thread, and FA/LB mounting (the series uses no back cover or SDB). The -S magnet means you must migrate from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors. At 175 mm stroke, guard against rod side-loading to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ25X175-10-S (same bore/stroke/adjust)
- ✓ Same 165–175 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 MBLJ25X175-10-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X175-10-S FAQ
Yes, the MALJ25X175-10-S is discontinued. The direct replacement is the MBLJ25X175-10-S, which matches the 25 mm bore, 175 mm stroke, 10 mm adjust code, and G1/8 port. You will need to upgrade your position sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG switches for the new body.
The -10 adjust code provides a usable stroke window of 165-175 mm. Note that the rear screw is a travel stop that sets the end position, not a mechanical lock; it cannot hold a load without constant air pressure.
