This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X30-30-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 MALJ25X30-30-S

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X30-30-S
The AirTAC MALJ25X30-30-S is a discontinued double-acting, double-rod mini cylinder with a 25 mm bore and 30 mm stroke. It features a rear adjustable travel stop that lets you trim the end position by up to 30 mm, creating a usable window from 0 to 30 mm. The direct replacement is the MBLJ25X30-30-S, matching the bore, stroke, adjust code, and G1/8 port.
This SKU includes a magnet (-S) for position sensing. The MALJ uses the older CS1-M / DS1-M switches, while the MBLJ replacement upgrades to CMSG / DMSG / EMSG sensors. The MALJ features threaded covers, whereas the MBLJ uses a riveted rolling-packed body. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. A fixed rubber bumper softens the end impact.

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 MBLJ25X30-30-S carries the same ratings.
Theoretical Output Force (Ø25mm)

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 MBLJ25X30-30-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X30-30-S Is Used
Bottle Capper Height Set
Adjust the end position without adding external spacers on a beverage capping head, fine-tuning the 30 mm stroke to match varying cap heights.
Leather Stamp Press
Set the precise embossing depth on a leather goods stamping press, relying on the rear stop to prevent over-compression of the material.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X30-30-S with MBLJ25X30-30-S
To replace the MALJ25X30-30-S, order the MBLJ25X30-30-S. Confirm the 25 mm bore, 30 mm stroke, 30 mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). The -S magnet means a sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. Remember the adjuster is a stop, not a lock; use an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ25X30-30-S (same bore/stroke/adjust)
- ✓ Same 0–30 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 MBLJ25X30-30-S instead of this discontinued model.
