This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X100-10S, 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 MALJ25X100-10-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X100-10-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 90 to 100 mm. This model is discontinued — the direct replacement is the MBLJ25X100-10-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-10-S
The AirTAC MALJ25X100-10-S is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. The direct replacement is the MBLJ25X100-10-S, matching the 25 mm bore, G1/8 port, and mounting footprint.
Two upgrade details define the MBLJ successor: the older MALJ uses threaded covers and a CS1-M / DS1-M magnet sensor track, while the MBLJ features a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. This -S SKU supports sensors, but the adjuster is strictly a travel stop, not a lock; it cannot hold a load without live air. End impacts rely on a fixed rubber bumper, not an adjustable air cushion.

| Bore size | Ø25 mm |
| Stroke | 100 mm |
| Adjustable window | 90 – 100 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

| 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 MBLJ25X100-10-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 MBLJ25X100-10-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-10-S Is Used
Dispenser Nozzle Height Trim
Fine-tune the retraction distance of an adhesive dispensing nozzle by up to 10 mm, preventing product collisions without swapping the entire cylinder body.
Light Press Pin Insertion
Press small alignment pins into connector housings, relying on the 206 N pull force to retract the tool cleanly after the insertion cycle completes.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-10-S with MBLJ25X100-10-S
To replace the MALJ25X100-10-S with the MBLJ25X100-10-S, confirm the 25 mm bore, 100 mm stroke, 10 mm adjust code, G1/8 port, and PT thread form. Mounting is Basic, FA, or LB only (no back cover or SDB). Remember to switch your CS1-M / DS1-M sensors to CMSG / DMSG / EMSG for the new body. The 10 mm adjuster sets the end position but is not a load lock.
At 100 mm stroke, side-load and rod-bending risks are moderate, so ensure rigid front mounting to guide the 10 mm rod.
Upgrade checklist
- ✓ Order the MBLJ25X100-10-S (same bore/stroke/adjust)
- ✓ Same 90–100 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 MBLJ25X100-10-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-10-S FAQ
Yes, the MALJ25X100-10-S is discontinued. The direct replacement is the MBLJ25X100-10-S, which matches the 25 mm bore, 100 mm stroke, 10 mm adjust code, and G1/8 port. You will need to upgrade your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The 10 mm adjuster is a travel stop that lets you trim the usable stroke window down to 90 mm; it does not lock the load without air pressure, and impacts are softened by a fixed rubber bumper.
