This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X300-20S, 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).

The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X300-20-S 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 280 to 300 mm. This model is discontinued — the direct replacement is the MBLJ32X300-20-S.
The AirTAC MALJ32X300-20-S is a discontinued double-acting double-rod mini cylinder with a 32 mm bore and 300 mm stroke. A rear stopper trims up to 20 mm, giving a usable 280-300 mm end-position window. The direct replacement is the MBLJ32X300-20-S, matching bore, stroke, force, port, and mounting.
This -S SKU carries a magnet for CS1-M / DS1-M switches, while the MBLJ upgrades to CMSG / DMSG / EMSG sensors. The MALJ uses threaded covers and a fixed rubber bumper, whereas the MBLJ features a riveted rolling-packed body. The adjuster is a travel stop, not a lock, so it cannot hold a load without live air pressure.

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 MBLJ32X300-20-S carries the same ratings.
| 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 MBLJ32X300-20-S matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 32 | Bore size in mm (20/25/32/40). |
| ×300 | Nominal stroke length in mm. |
| -20 | Adjustable amount: trim the end to a 280–300 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 the end position to maintain exact wire tension during slip ring winding, preventing snags on the 12 mm rod over the long 300 mm stroke.
Adjust the rear stopper to set a precise nozzle height for epoxy dispensing, leveraging the fixed rubber bumper to soften the 563 N end impact.
Replace the MALJ32X300-20-S with the direct replacement MBLJ32X300-20-S, confirming the 32 mm bore, 300 mm stroke, 20 mm adjust code, G1/8 port, M10x1.25 rod thread, and PT thread form. Mounting is FA or LB only, with no back cover or SDB. The -S magnet changes switch families from CS1-M / DS1-M to CMSG / DMSG / EMSG. At 300 mm stroke, rod side-load and bending risks are high, so guide the load carefully. The rear adjuster sets position but does not lock the load.
Upgrade checklist
Yes, the MALJ32X300-20-S is discontinued. The direct replacement is the MBLJ32X300-20-S, matching the 32 mm bore, 300 mm stroke, 20 mm adjust code, G1/8 port, and force. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet switches from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The 20 mm adjust code is a rear travel stop that lets you trim the end position, creating a usable stroke window of 280-300 mm. It is a stop, not a lock, and cannot hold a load without live air.
