This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X30-20S, 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 MALJ32X30-20-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X30-20-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 10 to 30 mm. This model is discontinued — the direct replacement is the MBLJ32X30-20-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X30-20-S
The AirTAC MALJ32X30-20-S is a discontinued double-acting double-rod mini cylinder with a rear adjustable stroke. It has a 32 mm bore and a 30 mm stroke, but the 20 mm adjuster lets you trim the rear position to dial in an exact 10-30 mm usable window without external stops. The direct replacement is the MBLJ32X30-20-S.
This -S SKU includes a magnet for position sensing. On this MALJ it works with the older CS1-M / DS1-M switches, whereas the MBLJ upgrade uses the newer CMSG / DMSG / EMSG families. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ replacement features a riveted rolling-packed body. The adjuster is a travel stop that sets the end position; it does not hold the load without live air.

| Bore size | Ø32 mm |
| Stroke | 30 mm |
| Adjustable window | 10 – 30 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 MBLJ32X30-20-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 MBLJ32X30-20-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X30-20-S Is Used
Connector Pin Press
Fine-tune the insertion depth of header pins into plastic blocks without moving the cylinder body, relying on the fixed rubber bumper to absorb the 346 N pull impact.
Dispenser Nozzle Height
Adjust the end position to control the nozzle gap on a solder paste dispenser, preventing crashes on the board surface while the -S magnet tracks the cycle.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X30-20-S with MBLJ32X30-20-S
To replace the MALJ32X30-20-S, order the exact direct replacement MBLJ32X30-20-S. Confirm the 32 mm bore, 30 mm stroke, 20 mm adjust code, G1/8 port, PT thread, and FA/LB mounting (there is no back cover or SDB option). Because this is an -S SKU, note the sensor family change from CS1-M / DS1-M to CMSG / DMSG / EMSG. The rear adjuster is a travel stop, not a lock; add an external lock for held loads.
This 32 mm bore gives 563 N at 0.7 MPa and 82 kgf max.
Upgrade checklist
- ✓ Order the MBLJ32X30-20-S (same bore/stroke/adjust)
- ✓ Same 10–30 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 MBLJ32X30-20-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X30-20-S FAQ
Yes, the MALJ32X30-20-S is discontinued. The direct replacement is the MBLJ32X30-20-S, which keeps the same 32 mm bore, 30 mm stroke, 20 mm adjust code, G1/8 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The 20 mm adjuster lets you trim the rear position, giving a usable stroke window of 10-30 mm. The adjuster is a travel stop, not a lock.
