This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X450-20-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 MALJ32X450-20-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20-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 430 to 450 mm. This model is discontinued — the direct replacement is the MBLJ32X450-20-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20-S
The AirTAC MALJ32X450-20-S is a discontinued 32mm bore, double-acting double-rod mini cylinder with a rear adjustable stroke stopper. It gives a usable 430-450mm end-position window by trimming up to 20mm at the rear. The direct replacement is the MBLJ32X450-20-S, matching the bore, stroke, adjust code, and G1/8 port.
This SKU includes a -S magnet for CS1-M or DS1-M switches; the MBLJ upgrade moves to CMSG/DMSG/EMSG sensors and swaps the MAL threaded covers for a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock, so it cannot hold a load without live air. It uses a fixed rubber bumper, not an adjustable cushion. On a 450mm stroke, the 12mm rod is highly susceptible to bending from side loads, so rigid guidance is mandatory.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20-S Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20-S |

| Bore size | Ø32 mm |
| Stroke | 450 mm |
| Adjustable window | 430 – 450 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
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 MBLJ32X450-20-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 MBLJ32X450-20-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20-S Is Used
Long-Travel Pallet Squaring
Fine-tune the retract position by up to 20mm to square pallets on a 450mm transfer line, ensuring the 12mm rod pulls the fixture precisely into the machine datum.
Textile Fabric Take-Up
Adjust the end stop to vary the 450mm stroke window, controlling the tensioning roll on a fabric winding machine where the fixed rubber bumper absorbs the end impact.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20-S with MBLJ32X450-20-S
To replace the MALJ32X450-20-S with the MBLJ32X450-20-S, confirm the 32mm bore, 450mm stroke, 20mm adjust code, PT G1/8 port, and M10x1.25 rod thread. Mounting is FA or LB only, as there is no back-cover or SDB option. The -S magnet means you must upgrade your switches from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster sets the end position but is not a lock; add an external lock for held loads.
For a 450mm stroke, side-load and rod-bending risks are severe, so ensure rigid external guidance to prevent premature seal failure.
Upgrade checklist
- ✓ Order the MBLJ32X450-20-S (same bore/stroke/adjust)
- ✓ Same 430–450 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 MBLJ32X450-20-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-20-S FAQ
Yes, the MALJ32X450-20-S is discontinued. The direct replacement is the MBLJ32X450-20-S, which matches the 32mm bore, 450mm stroke, 20mm adjust code, and G1/8 port. You must upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG switches, and the body changes from threaded covers to a riveted rolling-packed design.
The 20mm adjust code lets you trim the rear position, creating a usable 430-450mm stroke window. The adjuster is a travel stop, not a lock; it cannot hold a load without live air.
