This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X70-20S, 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 MALJ32X70-20S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-20S 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 50 to 70 mm. This model is discontinued — the direct replacement is the MBLJ32X70-20S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-20S
The AirTAC MALJ32X70-20S is a discontinued 32mm bore, double-acting double-rod mini cylinder with a rear adjustable stroke stopper. It provides a usable extension window of 50-70mm by trimming up to 20mm off the 70mm base stroke. The direct replacement is the MBLJ32X70-20S, matching the bore, stroke, G1/8 port, and mounting.
This -S magnet model uses the older CS1-M / DS1-M reed switches, whereas the MBLJ upgrade uses CMSG / DMSG / EMSG sensors. The MALJ features threaded covers and a fixed rubber bumper, while the MBLJ replacement moves to a riveted rolling-packed body. The rear adjuster is a mechanical travel stop, not a lock; it cannot hold a load without live air pressure.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-20S Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-20S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X70-20S |
| Bore size | Ø32 mm |
| Stroke | 70 mm |
| Adjustable window | 50 – 70 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 MBLJ32X70-20S 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 MBLJ32X70-20S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-20S Is Used
PCB router Z-axis plunge
Dial the 50-70mm stroke window to set router bit depth on demand.
Aluminum extrusion cutoff saw
Fine-tune the saw blade's downstroke to exactly 65mm for clean miter cuts. The fixed rubber bumper absorbs the end-of-stroke shock without requiring an air cushion.
Carton flap folding tucker
Adjust the tucker arm reach to 55mm to clear varying box heights. The 346N pull force reliably retracts the arm out of the packaging flow.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-20S with MBLJ32X70-20S
To replace the MALJ32X70-20S, order the direct replacement MBLJ32X70-20S. Confirm the 32mm bore, 70mm stroke, 20mm adjust code, G1/8 port, and M10x1.25 rod thread. Mounting is Basic, FA, or LB only (no back cover or SDB). The -S magnet means you must upgrade your switches from the old CS1-M / DS1-M to the new CMSG / DMSG / EMSG family. Remember the adjuster sets end position but does not hold load without air.
Upgrade checklist
- ✓ Order the MBLJ32X70-20S (same bore/stroke/adjust)
- ✓ Same 50–70 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 MBLJ32X70-20S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X70-20S FAQ
Yes, the MALJ32X70-20S is discontinued. The direct replacement is the MBLJ32X70-20S, which matches the 32mm bore, 70mm stroke, 20mm adjust code, G1/8 port, and mounting. You will need to update your sensors from the old CS1-M / DS1-M to the new CMSG / DMSG / EMSG switches.
The -20 adjust code lets you trim up to 20mm at the rear, giving a usable stroke window of 50-70mm. The adjuster is a travel stop, not a lock.
