This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X75-75S, 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).

The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-75-S 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 0 to 75 mm. This model is discontinued — the direct replacement is the MBLJ20X75-75-S.
The AirTAC MALJ20X75-75-S is a discontinued adjustable-stroke mini cylinder. Its direct replacement is the MBLJ20X75-75-S, which shares the exact bore, stroke, force, and port. This double-acting double-rod unit trims up to 75 mm at the rear screw, yielding a usable window of 0-75 mm for dialling in the end position.
The rear adjuster functions purely as a travel stop to set the position; it does not hold the load without live air. This MALJ features a -S magnet compatible with the older CS1-M / DS1-M switches, while the MBLJ replacement upgrades to CMSG / DMSG / EMSG sensors. The original uses threaded covers, whereas the MBLJ uses a riveted rolling-packed body. Impact is absorbed by 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 MBLJ20X75-75-S carries the same ratings.

| 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 MBLJ20X75-75-S matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 20 | Bore size in mm (20/25/32/40). |
| ×75 | Nominal stroke length in mm. |
| -75 | Adjustable amount: trim the end to a 0–75 mm window. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBLJ uses CMSG/DMSG/EMSG). |
Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Fine-tune adhesive bead application by trimming the rear stopper, ensuring the 20 mm body fits tight cell layouts without external spacers.
Actuate and softly return small gripper levers using the fixed rubber bumper, absorbing end-of-stroke impact without requiring an air cushion.
To replace this MALJ20X75-75-S, install the direct replacement MBLJ20X75-75-S. Confirm the 20 mm bore, 75 mm stroke, 75 mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). The -S magnet requires switching from the old CS1-M / DS1-M switches to the CMSG / DMSG / EMSG family. Remember the adjuster is a stop, not a lock.
Upgrade checklist
Yes, the MALJ20X75-75-S is discontinued. The direct replacement is the MBLJ20X75-75-S, which matches the bore, stroke, adjust code, and port. You will only need to update your sensors from the old CS1-M / DS1-M to the new CMSG / DMSG / EMSG switches.
The usable stroke window is 0-75 mm. The rear screw is a travel stop only and cannot hold a load without air pressure.
