This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X80-100-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 MALJ25X80-100-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X80-100-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from -20 to 80 mm. This model is discontinued — the direct replacement is the MBLJ25X80-100-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-100-S
The AirTAC MALJ25X80-100-S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke. Because the 100 mm adjuster exceeds the 80 mm stroke, it yields a usable end-position window of 0-80 mm. The direct replacement is the MBLJ25X80-100-S, matching the bore, port, and force.
This -S SKU includes a magnet for position sensing. The older MALJ threaded cover works with CS1-M / DS1-M switches, while the MBLJ replacement features a riveted rolling-packed body and uses CMSG / DMSG / EMSG sensors. The rear adjuster is a travel stop that sets the end position; it does not hold a load without live air. End impact is softened by a fixed rubber bumper, as there is no adjustable air cushion.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-100-S Technical Specifications
| Model | Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-100-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ25X80-100-S |
| Bore size | Ø25 mm |
| Stroke | 80 mm |
| Adjustable window | -20 – 80 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 MBLJ25X80-100-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 MBLJ25X80-100-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-100-S Is Used
PCB Depaneling Saw
Dials the cutting blade extension down to a 0-80 mm window.
Dispensing Valve Depth
Sets the exact nozzle height for epoxy dotting on electronic connectors. The rear stopper allows rapid reach tuning without swapping physical spacer rings on the 25 mm bore body.
Lightweight Part Pressing
Presses plastic clips into housings. The 206 N pull force retracts the rod cleanly, while the fixed rubber bumper absorbs the end-of-stroke impact during repetitive assembly.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-100-S with MBLJ25X80-100-S
To replace this MALJ25X80-100-S, order the MBLJ25X80-100-S. Confirm the 25 mm bore, 80 mm stroke, 100 mm adjust code, G1/8 port, PT thread, and magnet. Mounting is Basic, FA, or LB only (no back cover or SDB). Note the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster sets reach but is not a lock; add an external lock to hold loads without air.
For sizing flexibility, stepping down to the 20 mm bore drops the 0.5 MPa push force to 157 N. Stepping up to the 32 mm bore increases it to 402 N. This 25 mm bore provides a middle-ground 245 N, ideal for compact tasks needing precise depth dialing.
Upgrade checklist
- ✓ Order the MBLJ25X80-100-S (same bore/stroke/adjust)
- ✓ Same -20–80 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 MBLJ25X80-100-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-100-S FAQ
Yes, the MALJ25X80-100-S is discontinued. The direct replacement is the MBLJ25X80-100-S, which matches the 25 mm bore, 80 mm stroke, 100 mm adjust code, G1/8 port, and mounting. You will need to upgrade your position sensors, as the older CS1-M / DS1-M switches are replaced by CMSG / DMSG / EMSG sensors on the MBL line.
The 100 mm adjuster on an 80 mm stroke creates a usable end-position window of 0-80 mm. The rear screw is a travel stop, not a lock, so it cannot hold a load without live air pressure.
