This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ32X20-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ32X20-20 in place of this model. 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 MALJ32X20-20
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X20-20 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 0 to 20 mm. This model is discontinued — the drop-in replacement is the MBLJ32X20-20.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X20-20
The AirTAC MALJ32X20-20 is a discontinued double-acting single-rod mini cylinder. The drop-in replacement is the MBLJ32X20-20, matching the 32mm bore, 20mm stroke, and 20mm adjust code. This SKU provides a usable stroke window of 0-20mm via a rear screw stopper, yielding 402N push and 346N pull force at 0.5MPa.
Because this model lacks the -S suffix, it has no magnet and cannot accept a position sensor. 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 original MALJ uses threaded covers and a fixed rubber bumper, whereas the MBLJ upgrade features a riveted rolling-packed body.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X20-20 Is Used
PCB Router Clamping
Dials the exact 0-20mm clamping reach on a PCB depaneling router, using 402N of push force at 0.5MPa to hold boards firmly without cracking the substrate.
Dispenser Nozzle Depth
Fine-tunes the Z-axis stop for an adhesive dispensing nozzle, allowing operators to trim the 20mm stroke to prevent crushing delicate plastic housings.
Leather Press Feeder
Acts as an adjustable depth-stop for a small leather embossing press, setting the precise bottom position to avoid over-compressing the material.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X20-20 with MBLJ32X20-20
To replace the MALJ32X20-20, specify the MBLJ32X20-20. Confirm the G1/8 port, M10x1.25 rod-end thread, and FA or LB mounting (there is no back-cover or SDB option). If you previously used a magnet, note that the MBLJ requires CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M switches. The adjuster is a stop, not a lock.
For sizing flexibility, step down to a 25mm bore for 245N push at 0.5MPa, or step up to a 40mm bore for 628N push at 0.5MPa with a G1/4 port.
Upgrade checklist
- ✓ Order the MBLJ32X20-20 (same bore/stroke/adjust)
- ✓ Same 0–20 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 MBLJ32X20-20 instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X20-20 FAQ
Yes, the MALJ32X20-20 is discontinued. The exact drop-in replacement is the MBLJ32X20-20, which matches the 32mm bore, 20mm stroke, 20mm adjust code, G1/8 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if a magnet is added.
The usable stroke window is 0-20mm. At 0.5MPa it provides 402N push and 346N pull force; at 0.7MPa it provides 563N push; and the maximum force is 82kgf at 1.0MPa. Note that because this specific SKU lacks a magnet (-S), it cannot accept a position sensor.
