This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X50-30, 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).

The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X50-30 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 20 to 50 mm. This model is discontinued — the direct replacement is the MBLJ32X50-30.
The AirTAC MALJ32X50-30 is a discontinued double-acting mini cylinder with a 30 mm rear stroke adjuster. It provides a usable travel window of 20-50 mm. The direct replacement is the MBLJ32X50-30, matching the bore, stroke, adjust code, G1/8 port, and mounting.
This SKU has no -S magnet, so it cannot accept a position sensor. The rear adjuster is a travel stop that sets the end position but does not hold the load without live air. It uses a fixed rubber bumper, not an adjustable air cushion. The original MALJ features threaded covers and a 12 mm carbon-steel rod, while the MBLJ upgrade shifts to a riveted rolling-packed body.

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 MBLJ32X50-30 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 MBLJ32X50-30 matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 32 | Bore size in mm (20/25/32/40). |
| ×50 | Nominal stroke length in mm. |
| -30 | Adjustable amount: trim the end to a 20–50 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 clamp reach on a leather embossing fixture without machining new spacers, using the 30 mm rear adjuster to accommodate varying hide thicknesses.
Drive delicate Molex connector pins into housings on an assembly line, stopping the rod short of the full 50 mm to prevent buckling the brass contacts.
To replace this MALJ32X50-30 with the MBLJ32X50-30, confirm the 32 mm bore, 50 mm stroke, 30 mm adjust code, PT G1/8 port, and M10x1.25 rod thread. Mounting is FA or LB only; there is no back cover or SDB option. Because this SKU lacks the -S magnet, it cannot support a sensor, whereas upgrading to an MBLJ-S allows modern CMSG or DMSG switches instead of the legacy CS1-M or DS1-M. Remember the adjuster is a stop, not a lock.
For sizing flexibility, stepping down to a 25 mm bore drops the push force to 245 N at 0.5 MPa, while stepping up to a 40 mm bore increases it to 628 N and changes the port to G1/4. At 50 mm stroke, rod side-load bending is minimal, but keep the load axially aligned to protect the 12 mm rod.
Upgrade checklist
Yes, the MALJ32X50-30 is discontinued. The direct replacement is the MBLJ32X50-30, which matches the 32 mm bore, 50 mm stroke, 30 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The -30 adjust code means you can trim up to 30 mm at the rear, creating a usable stroke window of 20-50 mm. The adjuster is a travel stop, not a lock, and this non-S SKU cannot take a position sensor.
