This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X125-75S, 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 MALJ25X125-75-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X125-75-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 50 to 125 mm. This model is discontinued — the direct replacement is the MBLJ25X125-75-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X125-75-S
The AirTAC MALJ25X125-75-S is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. It features a 25mm bore, 125mm stroke, and a 75mm rear adjuster, providing a usable end-position window of 50-125mm. The direct replacement is the MBLJ25X125-75-S, matching bore, stroke, force, and port size.
This -S SKU includes a magnet for CS1-M or DS1-M switches; the MBLJ upgrade uses CMSG, DMSG, or EMSG sensors. The MALJ uses threaded covers, whereas the MBLJ features a riveted rolling-packed body. The rear adjuster acts as a travel stop to fine-tune reach without external stops, but it is not a lock and will not hold a load without live air. Impact is absorbed by a fixed rubber bumper, not an adjustable air cushion.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X125-75-S Technical Specifications

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ25X125-75-S |
| Bore size | Ø25 mm |
| Stroke | 125 mm |
| Adjustable window | 50 – 125 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 MBLJ25X125-75-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 MBLJ25X125-75-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X125-75-S Is Used
Variable Stroke Pick-and-Place
Adjust the rear stopper by up to 75mm to grab parts from varying tray depths without repositioning the cylinder body, saving machine teardown time.
Carton Flap Folding Arm
Fine-tune the folding arm reach to handle different box heights, relying on the 206N pull force at 0.5 MPa to retract the arm cleanly under the flap.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X125-75-S with MBLJ25X125-75-S
To replace the MALJ25X125-75-S, order the exact direct replacement MBLJ25X125-75-S. Confirm the 25mm bore, 125mm stroke, 75mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). Swap the CS1-M/DS1-M sensors for CMSG/DMSG/EMSG switches. Remember the adjuster is a stop, not a lock.
At 125mm stroke, minimize side-load to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ25X125-75-S (same bore/stroke/adjust)
- ✓ Same 50–125 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 MBLJ25X125-75-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X125-75-S FAQ
Yes, the MALJ25X125-75-S is discontinued. The direct replacement is the MBLJ25X125-75-S, which matches the 25mm bore, 125mm stroke, 75mm adjust code, G1/8 port, and FA/LB mounting. You must upgrade your sensors from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
The 75mm adjuster lets you trim the 125mm stroke, giving a usable end-position window of 50-125mm. The adjuster is a travel stop, not a lock.
