This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X90-50S, 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 MALJ32X90-50S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-50S 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 40 to 90 mm. This model is discontinued — the direct replacement is the MBLJ32X90-50S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-50S
The AirTAC MALJ32X90-50S is a discontinued double-acting double-rod cylinder with a 32 mm bore and a 90 mm stroke. It is discontinued and the direct replacement is the MBLJ32X90-50S. The 50 mm rear adjuster creates a usable end-position window of 40-90 mm, letting you dial in reach without external stops.
The rear screw is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The fixed rubber bumper softens end impact, but this is not an adjustable cushion. Upgrading to the MBLJ32X90-50S changes the sensor family from the older CS1-M/DS1-M to CMSG/DMSG/EMSG and swaps the threaded covers for a riveted rolling-packed body.

| Adjustable window | 40 – 90 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 |

| 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 MBLJ32X90-50S 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 MBLJ32X90-50S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-50S Is Used
Carton Flap Tucking
Fine-tune the tucker arm reach on a packaging line, trimming up to 50 mm at the rear to accommodate varying corrugated box heights without machining new brackets.
Aluminum Extrusion Notching
Adjust the end position for a notching fixture, ensuring the 346 N pull force cleanly retracts the tooling from the extrusion profile without over-travel.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X90-50S with MBLJ32X90-50S
To replace this MALJ32X90-50S with the MBLJ32X90-50S, confirm the 32 mm bore, 90 mm stroke, 50 mm adjust code, G1/8 port, PT thread, and FA/LB mounting. There is no back cover or SDB option. The -S magnet on your MALJ takes CS1-M/DS1-M switches, while the MBLJ requires CMSG/DMSG/EMSG sensors. Remember the adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ32X90-50S (same bore/stroke/adjust)
- ✓ Same 40–90 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 MBLJ32X90-50S instead of this discontinued model.
