This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X90-10-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 MALJ25X90-10-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X90-10-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 80 to 90 mm. This model is discontinued — the direct replacement is the MBLJ25X90-10-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X90-10-S
The AirTAC MALJ25X90-10-S is a discontinued double-acting double-rod mini cylinder with a rear adjustable stroke stopper. It provides a usable stroke window of 80-90 mm by trimming up to 10 mm at the rear.
The direct replacement is the MBLJ25X90-10-S. This upgrade shares the same G1/8 port, M10x1.25 rod thread, and 50 kgf max force, but moves from threaded covers to a riveted rolling-packed body. The -S magnet switches from the older CS1-M / DS1-M sensors to the modern CMSG / DMSG / EMSG family. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Impact is softened by a fixed rubber bumper.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X90-10-S Technical Specifications
| Model | Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X90-10-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ25X90-10-S |
| Bore size | Ø25 mm |
| Stroke | 90 mm |
| Adjustable window | 80 – 90 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 MBLJ25X90-10-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 MBLJ25X90-10-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X90-10-S Is Used
PCB Depaneling Router
Dialing the end position down 10 mm lets a 245 N pin retract a depaneling router bit clear of the board without moving the fixture.
Connector Pin Insertion
A travel stop sets the exact 80 mm insertion depth for Delphi connector pins, preventing over-travel while the rod retracts smoothly.
Light-Part Ejector
Trimming the stroke by 5 mm prevents the 10 mm rod from bottoming out the rubber bumper when ejecting plastic caps from a mold.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X90-10-S with MBLJ25X90-10-S
To replace the MALJ25X90-10-S, order the exact direct replacement MBLJ25X90-10-S. Confirm the 25 mm bore, 90 mm stroke, 10 mm adjust code, PT G1/8 port, and FA or LB mounting (there is no back cover or SDB option). The -S magnet requires a sensor family change from CS1-M / DS1-M to CMSG / DMSG / EMSG. Remember the adjuster is a stop, not a lock.
Both neighbours share the mini form factor without ISO standard constraints.
Upgrade checklist
- ✓ Order the MBLJ25X90-10-S (same bore/stroke/adjust)
- ✓ Same 80–90 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 MBLJ25X90-10-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X90-10-S FAQ
Yes, the MALJ25X90-10-S is discontinued. The direct replacement is the MBLJ25X90-10-S, which matches the 25 mm bore, 90 mm stroke, 10 mm adjust, G1/8 port, and 50 kgf max force. You will need to upgrade your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG switches.
The 10 mm adjuster is a travel stop that lets you shorten the usable stroke window down to 80 mm; it does not lock the load without live air, and end impact is softened only by a fixed rubber bumper.
