This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X100-40S, 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).

This model is discontinued — the direct replacement is the MBLJ25X100-40-S.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-40-S
The AirTAC MALJ25X100-40-S is a discontinued double-acting, double-rod mini cylinder with a 40mm rear adjustable stroke stopper. It provides a usable reach window of 60-100mm. The direct replacement is the MBLJ25X100-40-S.
This SKU features a magnet (-S) for position sensing. The older MALJ uses CS1-M/DS1-M switches, while the MBLJ replacement upgrades to CMSG/DMSG/EMSG sensors. The MALJ has 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. Impact is softened by a fixed rubber bumper, as there is no adjustable air cushion.

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 MBLJ25X100-40-S matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-40-S Is Used
Leather Skiving Gauge
Sets a precise end position to control the blade cut depth on thin hides, using the rear stopper to fine-tune the 100mm reach.
Small Parts Ejector
Trims the return stroke window to 60mm for fast cycling in a stamping die, using the fixed rubber bumper to soften the impact.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X100-40-S with MBLJ25X100-40-S
To replace the discontinued MALJ25X100-40-S, order the direct replacement MBLJ25X100-40-S. Confirm the 25mm bore, 100mm stroke, 40mm adjust code, G1/8 port, PT threads, and FA/LB mounting (no back cover or SDB). 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 100mm stroke, keep rod side-load minimized to prevent bending the 10mm rod.
Upgrade checklist
- ✓ Order the MBLJ25X100-40-S (same bore/stroke/adjust)
- ✓ Same 60–100 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 MBLJ25X100-40-S instead of this discontinued model.
