This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X250-50S, 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 MALJ25X250-50S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X250-50S 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 200 to 250 mm. This model is discontinued — the direct replacement is the MBLJ25X250-50S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X250-50S
The AirTAC MALJ25X250-50S is a discontinued adjustable-stroke mini cylinder. It provides a usable travel window of 200-250 mm by using a 50 mm rear stopper screw to trim the end position. The direct replacement is the MBLJ25X250-50S, matching the bore, stroke, adjuster, and G1/8 port.
The rear adjuster sets the end position but acts as a travel stop, not a lock, so it cannot hold a load without live air. An end impact is softened by a fixed rubber bumper, not an adjustable air cushion. For upgrades, the MBLJ25X250-50S shifts from these threaded covers to a riveted rolling-packed body, and the -S magnet switches from the older CS1-M / DS1-M sensors to the CMSG / DMSG / EMSG families.

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 MBLJ25X250-50S 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 MBLJ25X250-50S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X250-50S Is Used
Textile Loom Tensioning
Fine-tune the 250 mm reach on a textile loom guide bar, trimming 50 mm at the rear to perfectly align warp threads without adding external stops.
Carton Flap Folder
Adjust the stroke window down to 200 mm to fold varying corrugated carton flaps, relying on the fixed rubber bumper to absorb the repeated end impact.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X250-50S with MBLJ25X250-50S
Replace the MALJ25X250-50S directly with the MBLJ25X250-50S, confirming the 25 mm bore, 250 mm stroke, 50 mm adjust code, G1/8 port, and FA or LB mounting without any back cover or SDB. At 250 mm stroke, rod side-loading risks bending the 10 mm rod, so ensure rigid guiding. Remember the adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ25X250-50S (same bore/stroke/adjust)
- ✓ Same 200–250 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 MBLJ25X250-50S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X250-50S FAQ
Yes, the MALJ25X250-50S is discontinued. The direct replacement is the MBLJ25X250-50S, which matches the 25 mm bore, 250 mm stroke, 50 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The 50 mm rear adjuster creates a usable stroke window from 200 to 250 mm. The adjuster is a travel stop, not a lock, and will not hold a load without air pressure.
