This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X75-75S, 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 MALJ25X75-75-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X75-75-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 0 to 75 mm. This model is discontinued — the direct replacement is the MBLJ25X75-75-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X75-75-S
The AirTAC MALJ25X75-75-S is a discontinued double-acting double-rod mini cylinder with a rear adjustable stroke stopper. It trims up to 75 mm at the rear, giving a usable 0-75 mm window. The direct replacement is the MBLJ25X75-75-S.
The adjuster sets the end position but does not hold load without live air. This old -S magnet uses CS1-M/DS1-M switches, while the MBLJ upgrade uses CMSG/DMSG/EMSG. The MALJ has threaded covers and a fixed rubber bumper; the MBLJ features a riveted rolling-packed body.

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ25X75-75-S |
| Bore size | Ø25 mm |
| Stroke | 75 mm |
| Adjustable window | 0 – 75 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| 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 MBLJ25X75-75-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 MBLJ25X75-75-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X75-75-S Is Used
PCB Depaneling Saw Stop
Dial the 0-75 mm window to set the exact cut depth on a circular saw blade for singulating loaded PCB panels without cutting into the router bed.
Carton Flap Folder
Adjust the end position on the fly to fold varying corrugated box flap depths, relying on the fixed rubber bumper to soften the end impact.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X75-75-S with MBLJ25X75-75-S
Replace this MALJ25X75-75-S with the exact direct replacement MBLJ25X75-75-S. Confirm the 25 mm bore, 75 mm stroke, 75 mm adjust code, G1/8 PT port, and FA/LB mounting (no back cover or SDB). The rear adjuster is a travel stop, not a lock. The -S magnet changes sensor families from CS1-M/DS1-M to CMSG/DMSG/EMSG.
Both neighbours use the same G1/8 port.
Upgrade checklist
- ✓ Order the MBLJ25X75-75-S (same bore/stroke/adjust)
- ✓ Same 0–75 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 MBLJ25X75-75-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X75-75-S FAQ
Yes, the MALJ25X75-75-S is discontinued. The direct replacement is the MBLJ25X75-75-S, which matches the 25 mm bore, 75 mm stroke, 75 mm adjust code, G1/8 port, and FA/LB mounting. The upgrade shifts from threaded covers to a riveted body, and the -S magnet moves from CS1-M/DS1-M to CMSG/DMSG/EMSG switches.
The 75 mm adjust code lets you trim the rear position by up to 75 mm, creating a usable 0-75 mm stroke window. The adjuster is a travel stop, not a lock, so it cannot hold a load without live air pressure.
