This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X80-30S, 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 MALJ32X80-30-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-30-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 50 to 80 mm. This model is discontinued — the direct replacement is the MBLJ32X80-30-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-30-S
The AirTAC MALJ32X80-30-S is a discontinued double-acting mini cylinder with a rear adjustable stroke stopper. The direct replacement is the MBLJ32X80-30-S, matching the 32mm bore, 80mm stroke, 30mm adjust code, G1/8 port, and mounting footprint. The -30 adjuster lets you trim up to 30mm at the rear, creating a usable stroke window from 50mm to 80mm.
The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Impact is softened by a fixed rubber bumper, as there is no adjustable air cushion. This MALJ has threaded covers and an -S magnet for CS1-M/DS1-M switches, whereas the MBLJ upgrade uses a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-30-S Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-30-S |

| Stroke | 80 mm |
| Adjustable window | 50 – 80 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

| 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 MBLJ32X80-30-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 MBLJ32X80-30-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-30-S Is Used
Aluminum Extrusion Notching
Fine-tune the 80mm reach on an extrusion end-milling station to notch profiles accurately, relying on the fixed rubber bumper to absorb the 346N retraction snap.
Carton Flap Folder Limit
Adjust the rear stopper on a case erector to tuck minor flaps at varying carton heights, using the 30mm trim window instead of swapping the entire cylinder.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-30-S with MBLJ32X80-30-S
Replace this MALJ32X80-30-S directly with the MBLJ32X80-30-S. Confirm the 32mm bore, 80mm stroke, 30mm adjust code, PT/G1/8 port, and M10x1.25 rod-end thread. Mounting is Basic, FA, or LB only; there is no back cover or SDB option. The -S magnet on your old unit used CS1-M/DS1-M switches, so budget for CMSG/DMSG/EMSG sensors on the MBLJ. Remember the adjuster is a stop, not a lock, for holding loads.
To size both ways: stepping down to a 25mm bore drops the 0.5MPa push force to 245N, while stepping up to a 40mm bore increases it to 628N and widens the port to G1/4. At 80mm stroke, keep the rod guarded against side-load to prevent bending.
Upgrade checklist
- ✓ Order the MBLJ32X80-30-S (same bore/stroke/adjust)
- ✓ Same 50–80 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 MBLJ32X80-30-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X80-30-S FAQ
Yes, the MALJ32X80-30-S is discontinued. The direct replacement is the MBLJ32X80-30-S, which matches the 32mm bore, 80mm stroke, 30mm adjust code, G1/8 port, and mounting. You only need to update your sensors: the old -S magnet used CS1-M/DS1-M switches, while the MBLJ uses CMSG/DMSG/EMSG.
The -30 adjust code lets you trim up to 30mm at the rear, creating a usable stroke window from 50mm to 80mm. The adjuster is a travel stop, not a lock.
