This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X25-30SFA, 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 MALJ32X25-30SFA
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-30SFA 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 -5 to 25 mm. This model is discontinued — the direct replacement is the MBLJ32X25-30SFA.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-30SFA
The AirTAC MALJ32X25-30SFA is a discontinued double-acting mini cylinder with a 32 mm bore and 25 mm stroke. It features a rear screw stopper that lets you trim up to 30 mm, creating a usable end-position window from 0 to 25 mm. The direct replacement is the MBLJ32X25-30SFA, which matches the bore, stroke, force, G1/8 port, and FA flange mount.
This -S SKU includes a magnet for position sensing. The legacy MALJ uses CS1-M or DS1-M reed switches, while the MBLJ replacement upgrades to CMSG, DMSG, or EMSG solid-state sensors. The original MALJ has threaded covers, whereas the MBLJ features a riveted rolling-packed body. Both rely on a fixed rubber bumper to soften end impact and lack an adjustable air cushion.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-30SFA Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-30SFA |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X25-30SFA |
| Bore size | Ø32 mm |
| Stroke | 25 mm |
| Adjustable window | -5 – 25 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 MBLJ32X25-30SFA 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 MBLJ32X25-30SFA matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-30SFA Is Used
PCB Router Depth Stop
Dials the exact 0-25 mm descent on a depaneling router.
Connector Pin Insertion
Sets a precise bottoming height for pressing delicate header pins into nylon housings. The 346 N pull force safely retracts the tooling, while the adjustable window prevents over-travel that would buckle the pins.
Label Applicator Tamp
Fine-tunes the tamp stroke on a bottle labeling head.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-30SFA with MBLJ32X25-30SFA
To replace this MALJ32X25-30SFA, order the MBLJ32X25-30SFA. Confirm the 32 mm bore, 25 mm stroke, 30 mm adjust code, PT G1/8 port, and FA flange mounting. There is no back cover or SDB option. The -S magnet means you must change your sensors from the old CS1-M/DS1-M family to the MBLJ's CMSG/DMSG/EMSG series.
Remember the rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air.
Upgrade checklist
- ✓ Order the MBLJ32X25-30SFA (same bore/stroke/adjust)
- ✓ Same -5–25 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 MBLJ32X25-30SFA instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X25-30SFA FAQ
Yes, the MALJ32X25-30SFA is discontinued. The direct replacement is the MBLJ32X25-30SFA, matching the 32 mm bore, 25 mm stroke, 30 mm adjust code, G1/8 port, and FA mount. You will need to upgrade your position sensors from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
The usable stroke window is 0 to 25 mm because the 30 mm rear adjuster can trim the full 25 mm stroke. The adjuster is a travel stop, not a lock, so it cannot hold a load without live air.
