This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X25-30, 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).

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-30
The AirTAC MALJ25X25-30 is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. The direct replacement is the MBLJ25X25-30, which matches the 25mm bore, 25mm stroke, G1/8 port, and mounting footprint. This SKU has no magnet (-S), so it cannot accept a position sensor. The -30 adjust code lets you trim up to 30mm at the rear, yielding a usable end-position window from 0 to 25mm.
It uses a fixed rubber bumper, not an adjustable air cushion. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The original MALJ uses threaded covers and PT threads, while the MBLJ upgrade features a riveted rolling-packed body for greater structural integrity.

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 MBLJ25X25-30 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 MBLJ25X25-30 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-30 Is Used
Wire Stripping Clamp
Fine-tune the clamping reach on an automated wire stripping line, adjusting the end position by up to 30mm to accommodate different wire gauge stripping lengths without changing hardware.
Light Press Fit Pinning
Press small alignment pins into aluminum housings, relying on the 206N pull force to retract the tool, while using the rear stop to prevent over-travel on delicate parts.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-30 with MBLJ25X25-30
To replace the MALJ25X25-30, order the exact direct replacement MBLJ25X25-30, confirming the 25mm bore, 25mm stroke, -30 adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). Because this SKU lacks the -S magnet, it cannot hold a sensor; the MBLJ upgrade switches from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family if you need position sensing.
Remember the adjuster is a stop, not a lock; use an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ25X25-30 (same bore/stroke/adjust)
- ✓ Same -5–25 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 MBLJ25X25-30 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-30 FAQ
Yes, the MALJ25X25-30 is discontinued. The direct replacement is the MBLJ25X25-30, which keeps the same 25mm bore, 25mm stroke, -30 adjust code, G1/8 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if you add a magnet.
The usable adjustable window is 0 to 25mm (trimming up to 30mm from the 25mm stroke). At 0.7 MPa push is 343N, and the maximum force is 50kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion.
