This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X110-20-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 MALJ25X110-20-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X110-20-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 90 to 110 mm. This model is discontinued — the direct replacement is the MBLJ25X110-20-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X110-20-S
The AirTAC MALJ25X110-20-S is a discontinued double-acting, double-rod mini cylinder with a 25mm bore and a 110mm stroke. The -20 adjust code lets you trim up to 20mm at the rear screw, creating a usable stroke window from 90 to 110mm. The direct replacement is the MBLJ25X110-20-S, matching your bore, stroke, adjuster, and G1/8 port.
This -S SKU includes a magnet for CS1-M or DS1-M reed switches; the MBLJ replacement upgrades this to CMSG, DMSG, or EMSG sensors. The MALJ uses threaded covers and a fixed rubber bumper to soften end impact, while the MBLJ features a riveted rolling-packed body. Remember that the rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air pressure.

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 MBLJ25X110-20-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 MBLJ25X110-20-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X110-20-S Is Used
PCB Depaneling Saw Feed
Dial the rear stop to trim the 110mm stroke down to 90mm, setting the exact advance depth for a depaneling router blade without repositioning the entire cylinder block.
Carton Flap Folding Arm
Adjust the stroke window on a packaging line flap-folder to sync with changing box heights, relying on the fixed rubber bumper to absorb the 110mm stroke end impact.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X110-20-S with MBLJ25X110-20-S
To replace the MALJ25X110-20-S, order the exact direct replacement MBLJ25X110-20-S. Confirm the 25mm bore, 110mm stroke, 20mm adjust code, PT G1/8 port, and FA or LB mounting (no back cover or SDB). The -S magnet means you must upgrade your sensors from the older CS1-M/DS1-M family to the CMSG/DMSG/EMSG series. The rear screw is a travel stop, not a lock, so add an external lock for held loads.
At 110mm stroke, watch rod-to-side-load bending on the 10mm rod; use guide rails to prevent binding on long reaches.
Upgrade checklist
- ✓ Order the MBLJ25X110-20-S (same bore/stroke/adjust)
- ✓ Same 90–110 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 MBLJ25X110-20-S instead of this discontinued model.
