This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X85-75-S, 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 MALJ25X85-75-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X85-75-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 10 to 85 mm. This model is discontinued — the direct replacement is the MBLJ25X85-75-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X85-75-S
The AirTAC MALJ25X85-75-S is a discontinued adjustable-stroke mini cylinder. It is a double-acting double rod unit with a 25mm bore and 85mm stroke. The 75mm rear adjuster creates a usable end-position window of 10-85mm. The direct replacement is the MBLJ25X85-75-S, matching bore, stroke, port and force.
This SKU uses a G1/8 port, an Ø10mm rod with an M10x1.25 thread end, and a -S magnet for CS1-M/DS1-M switches. The MBLJ upgrade shifts to CMSG/DMSG/EMSG sensors and a riveted rolling-packed body instead of threaded covers. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. End impact is softened by a fixed rubber bumper, as there is no adjustable air cushion.

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 MBLJ25X85-75-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 MBLJ25X85-75-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X85-75-S Is Used
Connector Insertion Press
Set a precise 45mm stroke to seat Molex terminals into housings. The fixed rubber bumper absorbs the 206N pull impact during rapid retraction, preventing housing damage.
Carton Flap Folder
Adjust the reach to 60mm to fold corrugated flaps on varying box heights. The rear stopper lets you tune the fold depth without swapping the cylinder or adding external spacers.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X85-75-S with MBLJ25X85-75-S
To replace the MALJ25X85-75-S, order the direct replacement MBLJ25X85-75-S. Confirm the 25mm bore, 85mm stroke, 75mm adjust code, G1/8 PT port, and FA/LB mounting (no back cover or SDB). The -S magnet changes sensor families from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster is a stop, not a lock; use an external lock for held loads.
At 85mm stroke, side-load and rod-bending risks are low, but ensure the M10x1.25 rod end alignment is true to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ25X85-75-S (same bore/stroke/adjust)
- ✓ Same 10–85 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 MBLJ25X85-75-S instead of this discontinued model.
