This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X60-75S, 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 MALJ20 Adjustable Mini Cylinder MALJ20X60-75S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-75S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from -15 to 60 mm. This model is discontinued — the direct replacement is the MBLJ20X60-75S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-75S
The AirTAC MALJ20X60-75S is a discontinued double-acting mini cylinder with a 20 mm bore and a 60 mm stroke. It is directly replaced by the MBLJ20X60-75S. The -75 adjust code lets you trim the rear end position by up to 75 mm, creating a usable stroke window of 0-60 mm.
This -S magnet model uses the older CS1-M / DS1-M switches, whereas the MBLJ replacement moves to CMSG / DMSG / EMSG sensors. The original MALJ features threaded covers, while the newer MBLJ uses a riveted rolling-packed body. Remember the adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air. The cylinder uses a fixed rubber bumper, not an adjustable air cushion.

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 MBLJ20X60-75S 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 MBLJ20X60-75S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-75S Is Used
PCB Depaneling Saw
Dial the 0-60 mm stroke window to set the exact cut depth on a circular saw blade. The 132 N pull force retracts the blade safely without over-traveling into the fixture.
Dispenser Valve Probing
Fine-tune the downstroke of a fluid dispensing needle. The rear stopper lets you adjust the 60 mm stroke to a precise 10 mm reach without machining new hard stops.
Connector Pin Insertion
Press delicate header pins into plastic housings.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-75S with MBLJ20X60-75S
To replace this MALJ20X60-75S, order the exact direct replacement MBLJ20X60-75S. Confirm the 20 mm bore, 60 mm stroke, 75 mm adjust code, G1/8 port, PT thread, and FA or LB mounting (no back cover or SDB is used). You must also swap your CS1-M / DS1-M sensors for CMSG / DMSG / EMSG switches. The rear adjuster is a stop, not a lock, so add an external lock if you need to hold a load.
If you need less force, there is no smaller MALJ bore, so you must step down to an external stopper.
Upgrade checklist
- ✓ Order the MBLJ20X60-75S (same bore/stroke/adjust)
- ✓ Same -15–60 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 MBLJ20X60-75S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-75S FAQ
Yes, the MALJ20X60-75S is discontinued. The direct replacement is the MBLJ20X60-75S, matching the 20 mm bore, 60 mm stroke, 75 mm adjust code, and G1/8 port. You will need to upgrade your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG, as the new body uses a riveted rolling-packed design instead of threaded covers.
The 75 mm adjust code lets you trim the 60 mm stroke, giving a usable window of 0-60 mm. Note that the adjuster is a travel stop, not a lock, and the cylinder relies on a fixed rubber bumper.
