This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X105-40-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 MALJ25X105-40-S
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X105-40-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 65 to 105 mm. This model is discontinued — the direct replacement is the MBLJ25X105-40-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X105-40-S
The AirTAC MALJ25X105-40-S is a discontinued double-acting double-rod mini cylinder with a 25mm bore and 105mm stroke. It is replaced by the direct replacement MBLJ25X105-40-S. The -40 adjuster lets you trim the rear travel by up to 40mm, yielding a usable 65-105mm end-position window. The MBLJ upgrade retains your exact bore, stroke, port, and mounting.
This -S magnet SKU works with CS1-M/DS1-M switches, while the MBLJ replacement uses CMSG/DMSG/EMSG sensors. The MALJ uses threaded covers, whereas the MBLJ features a riveted rolling-packed body. The fixed rubber bumper softens end impact, but the adjuster is a travel stop, not a lock. It 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 MBLJ25X105-40-S carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |

| 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 MBLJ25X105-40-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X105-40-S Is Used
Bottle Capper Height Adjust
Fine-tune the downward reach on a packaging line capping head without swapping hardware, trimming up to 40mm to adapt to varying container heights.
Leather Skiving Clamp
Secure varying leather thicknesses in a skiving machine, letting the 206N pull force hold the material while the stopper dials the exact blade clearance.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X105-40-S with MBLJ25X105-40-S
To replace the MALJ25X105-40-S, order the exact MBLJ25X105-40-S direct. Match your 25mm bore, 105mm stroke, 40mm adjust code, G1/8 port, PT threads, and FA/LB mounting. The MBLJ upgrade changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG and switches from threaded covers to a riveted body. Remember the rear adjuster sets the end position but does not lock the load.
Upgrade checklist
- ✓ Order the MBLJ25X105-40-S (same bore/stroke/adjust)
- ✓ Same 65–105 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 MBLJ25X105-40-S instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X105-40-S FAQ
Yes, the MALJ25X105-40-S is discontinued. The direct replacement is the MBLJ25X105-40-S, which matches the 25mm bore, 105mm stroke, 40mm adjust code, and G1/8 port. The MBLJ uses a riveted rolling-packed body instead of threaded covers, and its -S magnet works with CMSG/DMSG/EMSG switches rather than the older CS1-M/DS1-M sensors.
The -40 adjust code allows you to trim up to 40mm of rear travel, creating a usable stroke window from 65mm to 105mm. The adjuster is a travel stop, not a lock, and the fixed rubber bumper softens end impacts without holding the load without air.
