This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X40-30S, 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 MALJ32X40-30S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-30S 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 10 to 40 mm. This model is discontinued — the direct replacement is the MBLJ32X40-30S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-30S
The AirTAC MALJ32X40-30S is a discontinued 32mm bore, double-acting double-rod mini cylinder with a 40mm stroke and a 30mm rear adjuster. This gives a usable end-position window of 10-40mm. The direct replacement is the MBLJ32X40-30S, matching the bore, stroke, force, and port.
The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air. This unit has a fixed rubber bumper, not an adjustable cushion. It uses threaded covers and a CS1-M/DS1-M magnet sensor, whereas the MBLJ upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. There is no back cover or SDB option; mounting is FA or LB only.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-30S Technical Specifications

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X40-30S |
| Bore size | Ø32 mm |
| Stroke | 40 mm |
| Adjustable window | 10 – 40 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 MBLJ32X40-30S 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 MBLJ32X40-30S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-30S Is Used
Connector Insertion Press
Fine-tune the insertion depth of pin headers into plastic housings, leveraging the 30mm rear stopper to adjust reach on the fly for different connector heights.
Leather Skiving Roller
Control the gap on a leather skiving machine by adjusting the cylinder's end position, ensuring the 346N pull force maintains consistent roller pressure across varying hide thicknesses.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-30S with MBLJ32X40-30S
To replace the MALJ32X40-30S, order the MBLJ32X40-30S. Confirm the 32mm bore, 40mm stroke, 30mm adjust code, G1/8 port, PT thread, and FA/LB mounting. The -S magnet changes sensor families from the older CS1-M/DS1-M to the newer CMSG/DMSG/EMSG. Remember the rear adjuster is a travel stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ32X40-30S (same bore/stroke/adjust)
- ✓ Same 10–40 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 MBLJ32X40-30S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X40-30S FAQ
Yes, the MALJ32X40-30S is discontinued. The direct replacement is the MBLJ32X40-30S, which matches the 32mm bore, 40mm stroke, 30mm adjuster, G1/8 port, and force. You will only need to update your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 30mm adjuster lets you trim the 40mm stroke, creating a usable end-position window of 10-40mm. The adjuster is a travel stop, not a lock.
