This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X60-20SLB, 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 MALJ25X60-20SLB
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X60-20SLB 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 40 to 60 mm. This model is discontinued — the direct replacement is the MBLJ25X60-20SLB.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X60-20SLB
The AirTAC MALJ25X60-20SLB is a discontinued double-acting mini cylinder with a 25 mm bore, 60 mm stroke, and 20 mm rear adjuster. This yields a usable stroke window of 40-60 mm. The direct replacement is the MBLJ25X60-20SLB, matching the bore, stroke, adjust code, and LB foot mount.
This LB-mounted unit features a G1/8 port and an M10x1.25 rod end. The rear screw is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The fixed rubber bumper softens end impact. The -S magnet works with older CS1-M/DS1-M switches, while the MBLJ upgrade moves to CMSG/DMSG/EMSG sensors and a riveted rolling-packed body instead of these threaded covers.

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 MBLJ25X60-20SLB 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 MBLJ25X60-20SLB matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X60-20SLB Is Used
Carton Flap Folder
Fine-tune the reach on a packaging line carton sealer. The rear stopper lets you adjust the 60 mm stroke to perfectly fold varying corrugated flap heights without swapping hardware.
Pneumatic Tube Bender
Control the bend angle on an aluminum tube bender. The LB foot mount stabilizes the cylinder while the adjustable end position halts the rod precisely at the desired degree.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X60-20SLB with MBLJ25X60-20SLB
To replace this MALJ25X60-20SLB with the MBLJ25X60-20SLB, confirm the 25 mm bore, 60 mm stroke, 20 mm adjust code, G1/8 port, PT thread, and LB foot mount. Note the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. Remember the adjuster only sets end position and does not lock the load.
Upgrade checklist
- ✓ Order the MBLJ25X60-20SLB (same bore/stroke/adjust)
- ✓ Same 40–60 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 MBLJ25X60-20SLB instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X60-20SLB FAQ
Yes, the MALJ25X60-20SLB is discontinued. The direct replacement is the MBLJ25X60-20SLB, which matches the 25 mm bore, 60 mm stroke, 20 mm adjuster, G1/8 port, and LB mount. The MBLJ uses a riveted body and CMSG/DMSG/EMSG sensors instead of the older threaded covers and CS1-M/DS1-M switches.
The 20 mm rear adjuster gives a usable stroke window of 40-60 mm. The adjuster is a travel stop, not a lock, and the cylinder uses a fixed rubber bumper rather than an adjustable air cushion.
