This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X150-40S, 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 MALJ25X150-40-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X150-40-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 110 to 150 mm. This model is discontinued — the direct replacement is the MBLJ25X150-40-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-40-S
The AirTAC MALJ25X150-40-S is a discontinued double-acting adjustable-stroke mini cylinder. It provides a usable extension window of 110-150 mm by trimming up to 40 mm at the rear. The direct replacement is the MBLJ25X150-40-S, which matches the bore, stroke, force, and mounting.
This SKU includes a -S magnet for position sensing. The older MALJ uses CS1-M or DS1-M switches, while the MBLJ replacement upgrades to CMSG, DMSG, or EMSG sensors. The MALJ features threaded covers and a fixed rubber bumper to soften end impacts. The rear adjuster is a travel stop, not a mechanical lock; it sets the end position but cannot 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 MBLJ25X150-40-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 MBLJ25X150-40-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-40-S Is Used
Dispenser Nozzle Trim
Fine-tune the rear stop on an adhesive dispenser to vary shot break-off distance by up to 40 mm, ensuring the 206 N pull retracts the nozzle cleanly from cured epoxy.
Leather Skiving Guide
Adjust the end position on a leather skiving machine to match varying hide thicknesses, relying on the fixed rubber bumper to absorb repeated high-speed impacts.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-40-S with MBLJ25X150-40-S
To replace the MALJ25X150-40-S, order the direct replacement MBLJ25X150-40-S. Confirm the 25 mm bore, 150 mm stroke, 40 mm adjust code, G1/8 port, PT threads, and FA/LB mounting. The -S magnet means you must switch from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors. Remember the adjuster is a stop, not a lock.
At 150 mm stroke, keep the rod guided to prevent side-load bending.
Upgrade checklist
- ✓ Order the MBLJ25X150-40-S (same bore/stroke/adjust)
- ✓ Same 110–150 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 MBLJ25X150-40-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X150-40-S FAQ
Yes, the MALJ25X150-40-S is discontinued. The direct replacement is the MBLJ25X150-40-S, which matches the 25 mm bore, 150 mm stroke, 40 mm adjust, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M switches.
The usable stroke window is 110-150 mm. The full force set: push is 245 N and pull is 206 N at 0.5 MPa; push is 343 N at 0.7 MPa; and the maximum force is 50 kgf at 1.0 MPa. The 40 mm adjuster is a travel stop, not a lock.
