This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X60-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X60-20 in place of this model. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20 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 40 to 60 mm. This model is discontinued — the drop-in replacement is the MBLJ40X60-20.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20
The AirTAC MALJ40X60-20 is a discontinued double-acting single-rod cylinder with a rear adjustable stroke stop. It has a 40 mm bore, 60 mm stroke, and a 20 mm adjuster, giving a usable end-position window of 40-60 mm. At 0.5 MPa it delivers 628 N push and 528 N pull force. The drop-in replacement is the MBLJ40X60-20, matching the bore, stroke, G1/4 port, and mounting.
This SKU lacks the -S magnet option, so it cannot take a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body. The bumper softens end impact only; use an external lock for held loads.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20 Technical Specifications

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 MBLJ40X60-20 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20 Is Used
Printed Circuit Board Tester
Dial the rear stop to set a precise 45 mm probe depth for testing PCBs without reprogramming the machine, using the 628 N push force to seat spring pins.
Leather Embossing Press
Fine-tune the embossing depth within the 40-60 mm window to match varying leather thicknesses, relying on the fixed rubber bumper to absorb the 880 N impact at 0.7 MPa.
Pneumatic Tube Insertion Jig
Adjust the end position to push a fitting into a pneumatic tube to a precise stop, preventing over-insertion while leveraging the 40 mm bore's 128 kgf max force.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20 with MBLJ40X60-20
To replace the MALJ40X60-20, order the drop-in MBLJ40X60-20. Confirm the 40 mm bore, 60 mm stroke, 20 mm adjust code, G1/4 port, PT thread, and FA or LB mounting. There is no back-cover or SDB option. Because this SKU has no -S magnet, it cannot accept a sensor; the MBLJ upgrade moves to CMSG/DMSG/EMSG switches if you add the -S version. The adjuster is a travel stop, not a lock.
For sizing, the next size down is the 32 mm bore (402 N push at 0.5 MPa, G1/8 port), and the next size up is the 40 mm bore with a longer stroke if you need more reach. This 60 mm stroke is well within standard limits, so rod-bending side-load risks are low, but always keep the load guided.
Upgrade checklist
- ✓ Order the MBLJ40X60-20 (same bore/stroke/adjust)
- ✓ Same 40–60 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 MBLJ40X60-20 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X60-20 FAQ
Yes, the MALJ40X60-20 is discontinued. The exact drop-in replacement is the MBLJ40X60-20, matching the 40 mm bore, 60 mm stroke, 20 mm adjust code, G1/4 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design from the MALJ's threaded covers.
The 20 mm adjuster lets you trim the 60 mm stroke to any end position in the 40-60 mm usable window. The 40 mm bore delivers 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The adjuster is a travel stop, not a lock.
