This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X450-50-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 MALJ32X450-50-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-50-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 400 to 450 mm. This model is discontinued — the direct replacement is the MBLJ32X450-50-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-50-S
The AirTAC MALJ32X450-50-S is a discontinued adjustable-stroke, double-acting double-rod mini cylinder. The direct replacement is the MBLJ32X450-50-S, matching the 32 mm bore, port, and mounting.
This unit uses a fixed rubber bumper, not an adjustable air cushion. The rear adjuster sets the end position but does not hold the load without live air. Upgrading to the MBLJ32X450-50-S changes the sensor family from CS1-M / DS1-M to CMSG / DMSG / EMSG, and swaps the threaded covers for a riveted rolling-packed body.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-50-S Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-50-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X450-50-S |
| Bore size | Ø32 mm |
| Stroke | 450 mm |
| Adjustable window | 400 – 450 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 |
| Proof pressure | 1.5 MPa |
| 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 MBLJ32X450-50-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 MBLJ32X450-50-S matches these values.
Model Code: Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-50-S

| 32 | Bore size in mm (20/25/32/40). |
| ×450 | Nominal stroke length in mm. |
| -50 | Adjustable amount: trim the end to a 400–450 mm window. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBLJ uses CMSG/DMSG/EMSG). |
Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-50-S Is Used
Textile loom feed tray
Fine-tune the 450 mm tray extension without adding external stops, relying on the 346 N pull to retract the fabric guide.
Palletizer sweep restrictor
Trim 50 mm off the end position to sync the sweep arm with varying pallet heights, using the fixed rubber bumper to soften the impact.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-50-S with MBLJ32X450-50-S
Replace this MALJ32X450-50-S directly with the MBLJ32X450-50-S, confirming the 32 mm bore, 450 mm stroke, 50 mm adjust code, G1/8 port, and PT thread. Mounting is FA or LB only with no back cover or SDB. The -S magnet changes from CS1-M / DS1-M to CMSG / DMSG / EMSG switches. At 450 mm, the rod is prone to bending under side loads, so guide the load externally. The adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ32X450-50-S (same bore/stroke/adjust)
- ✓ Same 400–450 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 MBLJ32X450-50-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X450-50-S FAQ
Yes, the MALJ32X450-50-S is discontinued. The direct replacement is the MBLJ32X450-50-S, which matches the 32 mm bore, 450 mm stroke, 50 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG / DMSG / EMSG sensors instead of the CS1-M / DS1-M switches.
At 0.7 MPa, push is 563 N, with a maximum of 82 kgf at 1.0 MPa. The 50 mm adjuster lets you trim the 450 mm stroke down to a 400 mm minimum. Note that the adjuster is a travel stop, not a lock, and cannot hold the load without live air.
