This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X25-20S, 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).

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-20-S
The AirTAC MALJ32X25-20-S is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. The direct replacement is the MBLJ32X25-20-S, matching the 32mm bore, 25mm stroke, G1/8 port, and mounting. The rear adjuster lets you trim up to 20mm, creating a usable stroke window of 5-25mm. This -S SKU uses a magnet for CS1-M/DS1-M switches.
The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The MALJ uses threaded covers, while the MBLJ replacement upgrades to a riveted rolling-packed body. Both use a fixed rubber bumper to soften end impact. If you need to hold a load mechanically, add an external lock.

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 MBLJ32X25-20-S carries the same ratings.
Theoretical Output Force (Ø32mm)

| Max (@1.0 MPa) | 70 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 MBLJ32X25-20-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-20-S Is Used
Connector Insertion Press
Fine-tune the downward reach on a multi-pin connector press, preventing over-travel damage without recalculating fixed hard stops.
Small Part Ejector
Adjust the kick-out distance on a molding ejector to clear a 25mm maximum reach, relying on the fixed rubber bumper for soft contact.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-20-S with MBLJ32X25-20-S
To replace the MALJ32X25-20-S, order the MBLJ32X25-20-S. Confirm the 32mm bore, 25mm stroke, 20mm adjust code, G1/8 port, PT threads, and FA/LB mounting (no back cover or SDB). The -S magnet changes switch families from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ32X25-20-S (same bore/stroke/adjust)
- ✓ Same 5–25 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 MBLJ32X25-20-S instead of this discontinued model.
