This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X35-30, 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).

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X35-30
The AirTAC MALJ20X35-30 is a discontinued double-acting, double-rod mini cylinder with a 20mm bore and 35mm stroke. The -30 adjust code lets you trim up to 30mm at the rear, creating a usable end-position window of 5-35mm. The direct replacement is the MBLJ20X35-30, matching the bore, stroke, G1/8 port, and mounting.
This SKU has no -S magnet and cannot take a position sensor. The rear adjuster 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. Upgrading to the MBLJ20X35-30 moves you from threaded covers to a riveted rolling-packed body, and if you ever need a sensor, the MBLJ uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M family.

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 MBLJ20X35-30 carries the same ratings.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 132 N | 132 N |
| 0.7 MPa | 185 N | — |
| Max (@1.0 MPa) | 27 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 MBLJ20X35-30 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X35-30 Is Used
Micro-Dispense Valve Pin
Fine-tunes the stroke window on a micro-dispensing valve to control droplet size, where trimming the 35mm stroke by up to 30mm at the rear prevents syringe tip collisions.
Connector Alignment Finger
Acts as an adjustable locating finger on a small connector assembly station, using the 132N pull force to retract the guide and clear the workpiece for robotic pickup.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X35-30 with MBLJ20X35-30
Replace the MALJ20X35-30 with the direct replacement MBLJ20X35-30. Confirm the 20mm bore, 35mm stroke, -30 adjust code, G1/8 PT port, and M8x1.25 rod-end thread. Mounting is FA or LB only; there is no back cover or SDB option. Because this SKU lacks the -S magnet, it cannot accept a sensor. The adjuster is a stop, not a lock, so use an external lock for held loads.
Use the 25mm if your fixture needs more clamping power.
Upgrade checklist
- ✓ Order the MBLJ20X35-30 (same bore/stroke/adjust)
- ✓ Same 5–35 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 MBLJ20X35-30 instead of this discontinued model.
