This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X50-20-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 MALJ32 Adjustable Mini Cylinder MALJ32X50-20-S
The AirTAC MALJ32 Adjustable Mini Cylinder MALJ32X50-20-S 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 30 to 50 mm. This model is discontinued — the direct replacement is the MBLJ32X50-20-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-20-S
The AirTAC MALJ32X50-20-S is a discontinued double-acting double-rod mini cylinder with a 32 mm bore and 50 mm stroke. It features a rear screw stopper that lets you trim the end position by up to 20 mm, creating a usable stroke window of 30-50 mm. The direct replacement is the MBLJ32X50-20-S, which matches the bore, stroke, adjust code, G1/8 port, and FA/LB mounting.
This -S SKU includes a magnet for position sensing. The original MALJ uses CS1-M or DS1-M switches, while the MBLJ upgrade moves to CMSG, DMSG, or EMSG sensors. The MALJ has threaded covers, whereas the MBLJ features a riveted rolling-packed body. Both use a fixed rubber bumper, not an air cushion. The adjuster is a travel stop that sets the end position but does not hold load without live air.

| Bore size | Ø32 mm |
| Stroke | 50 mm |
| Adjustable window | 30 – 50 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |

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 MBLJ32X50-20-S 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 MBLJ32X50-20-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-20-S Is Used
PCB Router Depth Stop
Dial in a 40 mm reach on the 30-50 mm window to set precise Z-axis cutting depth on a printed circuit board router without swapping fixtures.
Carton Flap Folder
Adjust the end position on the fly to fold differing corrugated box heights, relying on the fixed rubber bumper to soften the stroke end impact.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-20-S with MBLJ32X50-20-S
To replace your MALJ32X50-20-S, order the exact direct replacement MBLJ32X50-20-S. Confirm your 32 mm bore, 50 mm stroke, 20 mm adjust code, PT G1/8 port, and M10x1.25 rod thread. Mounting remains Basic, FA, or LB only, as there is no back cover or SDB option. Remember the rear adjuster is a stop, not a lock; add an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ32X50-20-S (same bore/stroke/adjust)
- ✓ Same 30–50 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 MBLJ32X50-20-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-20-S FAQ
Yes, the MALJ32X50-20-S is discontinued. The direct replacement is the MBLJ32X50-20-S, matching the 32 mm bore, 50 mm stroke, 20 mm adjust code, and G1/8 port. You must change sensors: the MALJ uses CS1-M or DS1-M switches, while the MBLJ uses CMSG, DMSG, or EMSG switches.
The 20 mm adjust code is a rear travel stop that lets you shorten the 50 mm stroke, creating a usable 30-50 mm window. It sets the end position but does not hold the load without live air.
