This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X80-50S, 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 MALJ25X80-50-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X80-50-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 30 to 80 mm. This model is discontinued — the direct replacement is the MBLJ25X80-50-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-50-S
The AirTAC MALJ25X80-50-S is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. It features a 25mm bore, an 80mm standard stroke, and a 50mm rear adjuster, yielding a usable end-position window of 30-80mm. The direct replacement is the MBLJ25X80-50-S, matching the bore, stroke, force, G1/8 port, and mounting.
This -S variant includes a magnet for CS1-M or DS1-M switches; the MBLJ upgrade shifts to CMSG/DMSG/EMSG sensors. The MALJ uses threaded covers, whereas the MBLJ features a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air. End impact is absorbed by a fixed rubber bumper.

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 MBLJ25X80-50-S carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |

| 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 MBLJ25X80-50-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-50-S Is Used
Sheet Metal Press Brake
Fine-tunes the 80mm return position to set the exact bend depth on a light-gauge steel bracket, using the 206N pull force to lift the upper die.
Carton Folding Flap
Adjusts the end stop to 45mm to perfectly tuck minor carton flaps on a packaging line before tape application, preventing over-travel.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-50-S with MBLJ25X80-50-S
To replace the MALJ25X80-50-S, order the direct replacement MBLJ25X80-50-S. Confirm the 25mm bore, 80mm stroke, 50mm adjust code, G1/8 PT port, and FA/LB mounting (no back cover or SDB). Remember the adjuster is a stop, not a lock, so add an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ25X80-50-S (same bore/stroke/adjust)
- ✓ Same 30–80 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 MBLJ25X80-50-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X80-50-S FAQ
Yes, the MALJ25X80-50-S is discontinued. The direct replacement is the MBLJ25X80-50-S, which matches the 25mm bore, 80mm stroke, 50mm adjuster, force, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and the magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 50mm adjuster on the 80mm stroke creates a usable end-position window of 30-80mm. The adjuster acts as a travel stop, not a lock, and cannot hold a load without live air.
