This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X40-20S, 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).
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-20S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-20S 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 20 to 40 mm. This model is discontinued — the direct replacement is the MBLJ32X40-20S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-20S
The AirTAC MALJ32X40-20S is a discontinued double-acting mini cylinder with a rear adjustable stroke stopper. Its 20 mm adjust code trims the 40 mm stroke, yielding a usable end-position window of 20-40 mm.
The direct replacement is the MBLJ32X40-20S, matching the bore, stroke, port, and force. The old MALJ uses threaded covers and a CS1-M / DS1-M magnet, while the MBLJ upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air.

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 MBLJ32X40-20S carries the same ratings.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| 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 MBLJ32X40-20S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-20S Is Used
Bottle Capper Pre-load
Fine-tune the capping head pre-load on a rotary bottle capper; the rear stopper sets the exact 20-40 mm reach without adding external collars.
Leather Press Crease
Regulate the creasing depth on an industrial leather press, where the 346 N pull force retracts the rod while the stopper maintains a consistent material fold.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-20S with MBLJ32X40-20S
Replace the MALJ32X40-20S with the direct replacement MBLJ32X40-20S. Confirm the 32 mm bore, 40 mm stroke, 20 mm adjust code, G1/8 port, and PT thread. Mounting is FA or LB only; there is no back-cover or SDB option. The -S magnet switches from CS1-M / DS1-M to CMSG / DMSG / EMSG. Remember the adjuster is a stop, not a lock.
The fixed rubber bumper softens impact but is not an adjustable air cushion.
Upgrade checklist
- ✓ Order the MBLJ32X40-20S (same bore/stroke/adjust)
- ✓ Same 20–40 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 MBLJ32X40-20S instead of this discontinued model.
