This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X55-30-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 MALJ32X55-30-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X55-30-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 25 to 55 mm. This model is discontinued — the direct replacement is the MBLJ32X55-30-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X55-30-S
The AirTAC MALJ32X55-30-S is a discontinued 32mm bore adjustable-stroke mini cylinder. It provides a usable end-position window of 25-55mm by trimming up to 30mm at the rear screw. The direct replacement is the MBLJ32X55-30-S, matching bore, stroke, force, port, and mounting.
The rear adjuster is a travel stop, not a lock. Upgrade facts: the MALJ has threaded covers and uses CS1-M/DS1-M switches, while the MBLJ features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X55-30-S Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X55-30-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X55-30-S |
| Bore size | Ø32 mm |
| Stroke | 55 mm |
| Adjustable window | 25 – 55 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 MBLJ32X55-30-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 MBLJ32X55-30-S matches these values.
Model Code: Airtac MALJ32 Adjustable Mini Cylinder MALJ32X55-30-S

| -30 | Adjustable amount: trim the end to a 25–55 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 MALJ32X55-30-S Is Used
PCB Depaneling Saw
Sets a precise 25-55mm blade advance on an automated PCB routing saw.
Connector Pin Insertion
Feeds header pins into molded plastic connectors. The 30mm adjust window fine-tunes the 346N pull retraction so pins bottom out perfectly without damaging the housing.
Carton Flap Folder
Tucks minor flaps on a packaging line. The fixed rubber bumper absorbs the 563N extension impact at 0.7MPa, and the stopper sets flap depth for varying box sizes.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X55-30-S with MBLJ32X55-30-S
To replace this MALJ32X55-30-S, order the direct replacement MBLJ32X55-30-S. Confirm the 32mm bore, 55mm stroke, 30mm adjust code, G1/8 port, PT thread, and LB/FA mounting (no back cover or SDB). The -S magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG. Remember the adjuster sets end position but holds no load without live air.
At 55mm stroke, rod side-load is minimal, but long strokes risk bending.
Upgrade checklist
- ✓ Order the MBLJ32X55-30-S (same bore/stroke/adjust)
- ✓ Same 25–55 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 MBLJ32X55-30-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X55-30-S FAQ
Yes, the MALJ32X55-30-S is discontinued. The direct replacement is the MBLJ32X55-30-S, matching the 32mm bore, 55mm stroke, 30mm adjust code, G1/8 port, and mounting. You will only change the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG.
At 0.7MPa it pushes 563N, with a maximum of 82kgf at 1.0MPa. The 30mm adjust code creates a usable stroke window of 25-55mm. The adjuster is a travel stop, not a lock; it cannot hold a load without live air.
