This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X500-30-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).
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-30-S
The AirTAC MALJ32 Adjustable Mini Cylinder MALJ32X500-30-S 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 470 to 500 mm. This model is discontinued — the direct replacement is the MBLJ32X500-30-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-30-S
The AirTAC MALJ32X500-30-S is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. It provides a usable stroke window of 470-500 mm by trimming up to 30 mm at the rear screw. The direct replacement is the MBLJ32X500-30-S.
The -S magnet on this MALJ works with older CS1-M / DS1-M switches, while the MBLJ upgrade uses CMSG / DMSG / EMSG sensors. This MALJ has threaded covers; the MBLJ replacement uses a riveted rolling-packed body. The fixed rubber bumper softens end impact, but the adjuster is a travel stop, not a lock. It cannot hold a load without live air pressure.

| Bore size | Ø32 mm |
| Stroke | 500 mm |
| Adjustable window | 470 – 500 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
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 MBLJ32X500-30-S carries the same ratings.
Theoretical Output Force (Ø32mm)
| 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 MBLJ32X500-30-S matches these values.

| -30 | Adjustable amount: trim the end to a 470–500 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.
Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-30-S Is Used
Carton forming plungers
Fine-tune the 500 mm reach on a packaging erecting machine to fold varying box depths cleanly.
Palletizer push-off stops
Trim 30 mm off the rear travel to set an exact pallet push-off depth, avoiding external stop bolts on the frame.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-30-S with MBLJ32X500-30-S
To replace this MALJ32X500-30-S, order the exact direct replacement MBLJ32X500-30-S. Confirm the 32 mm bore, 500 mm stroke, 30 mm adjust code, G1/8 port, PT thread, and LB mounting (no back cover or SDB). The -S magnet shifts from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors. The adjuster sets end position but does not lock the load.
At 500 mm stroke, rod side-load and bending risks are high; use a guide to prevent binding.
Upgrade checklist
- ✓ Order the MBLJ32X500-30-S (same bore/stroke/adjust)
- ✓ Same 470–500 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 MBLJ32X500-30-S instead of this discontinued model.
