This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X80-75S, 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 MALJ25X80-75-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X80-75-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 5 to 80 mm. This model is discontinued — the direct replacement is the MBLJ25X80-75-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-75-S
The AirTAC MALJ25X80-75-S is a discontinued double-acting mini cylinder with a rear travel stop. It gives a usable stroke window of 5-80 mm. The direct replacement is the MBLJ25X80-75-S, which matches the 25 mm bore, 80 mm stroke, and 75 mm adjust code exactly.
This -S SKU has a magnet for CS1-M or DS1-M switches; the MBLJ upgrade moves to CMSG, DMSG, or EMSG sensors. The original uses threaded covers, while the replacement features a riveted rolling-packed body. Both rely on a fixed rubber bumper. The rear adjuster sets the end position but does not hold load without live air.

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 MBLJ25X80-75-S carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |

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 MBLJ25X80-75-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-75-S Is Used
Dispenser Nozzle Height
Fine-tune the retracted position of a glue dispensing nozzle on an electronics assembly line, trimming up to 75 mm at the rear to accommodate different substrate thicknesses.
Leather Press Tensioning
Adjust the end stroke on a leather embossing press to vary the compression distance, relying on the fixed rubber bumper to soften the impact at the end of travel.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-75-S with MBLJ25X80-75-S
To replace this MALJ25X80-75-S, order the MBLJ25X80-75-S. Confirm the G1/8 port, PT thread, and FA or LB mounting, as there is no back cover or SDB option. The -S magnet changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG. The 75 mm adjuster is a travel stop, not a lock, so add an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ25X80-75-S (same bore/stroke/adjust)
- ✓ Same 5–80 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 MBLJ25X80-75-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-75-S FAQ
Yes, the MALJ25X80-75-S is discontinued. The direct replacement is the MBLJ25X80-75-S, which shares the same 25 mm bore, 80 mm stroke, 75 mm adjust code, and G1/8 port. You will need to update your sensors, as the MBLJ uses CMSG, DMSG, or EMSG switches instead of the older CS1-M/DS1-M.
The 75 mm rear adjuster creates a usable stroke window from 5 mm to 80 mm. The adjuster is a travel stop, not a lock, and cannot hold a load without live air.
