This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X100-75, 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).

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-75
The AirTAC MALJ25X100-75 is a discontinued adjustable-stroke mini cylinder. Its rear screw stopper trims up to 75 mm, creating a usable end-position window from 25 mm to 100 mm. The direct replacement is the MBLJ25X100-75, matching the bore, stroke, adjust code, and G1/8 port.
This double-acting double-rod unit has a fixed rubber bumper, not an adjustable air cushion. The rear adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air. This SKU lacks the -S magnet, so it cannot take a position sensor. The original MALJ uses threaded covers and CS1-M/DS1-M switches; the MBLJ upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.

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 MBLJ25X100-75 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 MBLJ25X100-75 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-75 Is Used
Dispenser Nozzle Height
Fine-tunes the syringe tip standoff on a fluid dispensing station, trimming 75 mm of rear travel to prevent nozzle crash on varying substrate depths.
Wire Forming Bender
Sets the precise bend depth for copper wire forms, relying on the fixed rubber bumper to absorb the 206 N pull impact without requiring an external stop.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-75 with MBLJ25X100-75
To replace the MALJ25X100-75, use the MBLJ25X100-75 direct. Confirm the 25 mm bore, 100 mm stroke, 75 mm adjust code, G1/8 port, and PT thread. Mounting is FA or LB only; there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot accept a sensor; upgrading to the MBLJ with a -S magnet is required for CMSG/DMSG/EMSG switches. The adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ25X100-75 (same bore/stroke/adjust)
- ✓ Same 25–100 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 MBLJ25X100-75 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-75 FAQ
Yes, the MALJ25X100-75 is discontinued. The direct replacement is the MBLJ25X100-75, matching the 25 mm bore, 100 mm stroke, 75 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design but retains the same force and mounting footprint.
The 75 mm rear adjuster is a travel stop that creates a usable stroke window from 25 mm to 100 mm. It does not hold the load without live air, and this no-S SKU cannot accept a position sensor.
