This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X500-40-S, 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 MALJ32X500-40-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 460 to 500 mm. This model is discontinued — the direct replacement is the MBLJ32X500-40-S.
The AirTAC MALJ32X500-40-S is a discontinued double-acting, double-rod mini cylinder with a 32mm bore and 500mm stroke. The direct replacement is the MBLJ32X500-40-S, which matches the bore, stroke, 40mm adjust code, G1/8 port, and mounting. The rear stopper lets you trim up to 40mm, providing a usable end-position window of 460-500mm.
This -S SKU includes a magnet for CS1-M/DS1-M switches; the MBLJ upgrade shifts to CMSG/DMSG/EMSG sensors. The original MALJ uses threaded covers, while the MBLJ features a riveted rolling-packed body. The adjuster is a travel stop, not a lock, and the fixed rubber bumper softens end impact without providing air-cushioning. At 500mm, this stroke is non-standard for the 32mm bore, so confirm the exact overall length from the datasheet.

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 MBLJ32X500-40-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 MBLJ32X500-40-S matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 32 | Bore size in mm (20/25/32/40). |
| ×500 | Nominal stroke length in mm. |
| -40 | Adjustable amount: trim the end to a 460–500 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.
Dials the 460-500mm descent depth on a high-speed PCB depaneling router, preventing the 346N pull force from driving the spindle into the tooling base.
Sets the exact eject distance on a 500mm conveyor transfer, using the rear stopper to shorten the return by 40mm so the retracted rod clears the pallet guide.
Replace this MALJ with the MBLJ32X500-40-S by confirming the 32mm bore, 500mm stroke, 40mm adjust code, G1/8 port, PT thread, and FA/LB mounting (there is no back-cover or SDB option). The -S magnet requires swapping older CS1-M/DS1-M switches for CMSG/DMSG/EMSG sensors. The adjuster sets the end position but does not hold load without live air; use an external lock for suspended loads. Because the 500mm stroke is non-standard and maxes out the 32mm bore, watch for rod bending under side loads.
Upgrade checklist
Yes, the MALJ32X500-40-S is discontinued. The direct replacement is the MBLJ32X500-40-S, which matches the 32mm bore, 500mm stroke, 40mm adjust code, G1/8 port, and mounting. The MBLJ upgrade changes the threaded covers to a riveted rolling-packed body, and the -S magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors.
The 40mm adjust code lets you trim the rear position, giving a usable stroke window of 460-500mm. The adjuster is a travel stop, not a lock.
