This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X500-75-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 MALJ32X500-75-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-75-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 425 to 500 mm. This model is discontinued — the direct replacement is the MBLJ32X500-75-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-75-S
The AirTAC MALJ32X500-75-S is a discontinued double-acting, double-rod adjustable-stroke mini cylinder. It is directly replaced by the direct replacement MBLJ32X500-75-S. The 75 mm rear adjuster creates a usable stroke window of 425-500 mm, letting you fine-tune the end position without adding external stops. It includes a -S magnet for CS1-M / DS1-M switches.
The rear adjuster functions strictly as a travel stop to set the end position; it is not a lock and will not hold a load without live air pressure. A fixed rubber bumper softens end impact, but this is an adjustable stroke, not an adjustable cushion. The legacy MALJ uses threaded covers, while the MBLJ32X500-75-S upgrade features a riveted rolling-packed body and updates the sensor family to CMSG / DMSG / EMSG. Mounting is FA or LB only, with no back cover or SDB option.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-75-S Technical Specifications

| 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 MBLJ32X500-75-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 MBLJ32X500-75-S matches these values.
Model Code: Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-75-S

| ×500 | Nominal stroke length in mm. |
| -75 | Adjustable amount: trim the end to a 425–500 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 MALJ32X500-75-S Is Used
Textile loom beam let-off
The 500 mm extension manages tensioning beam travel in a weaving loom, while the 75 mm stopper adjustment fine-tunes the rest position to align warp threads without re-engineering the frame.
CNC lathe bar feeder pusher
Feeds raw bar stock into a spindle; the 346 N pull retracts the pusher safely. The rear stopper sets the exact feed depth for different part lengths, preventing spindle collision.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-75-S with MBLJ32X500-75-S
To replace the MALJ32X500-75-S, order the exact direct replacement MBLJ32X500-75-S. Confirm the 32 mm bore, 500 mm stroke, 75 mm adjust code, G1/8 port, PT thread, and FA/LB mounting. The -S magnet on your old MALJ used CS1-M / DS1-M switches; the MBLJ replacement requires CMSG / DMSG / EMSG sensors. Remember the rear adjuster is a travel stop, not a load lock.
At 500 mm stroke, the 12 mm rod is highly susceptible to side-load bending and deflection—ensure rigid guidance to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ32X500-75-S (same bore/stroke/adjust)
- ✓ Same 425–500 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 MBLJ32X500-75-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-75-S FAQ
Yes, the MALJ32X500-75-S is discontinued. The direct replacement is the MBLJ32X500-75-S, which matches the 32 mm bore, 500 mm stroke, 75 mm adjust code, G1/8 port, and force. You will need to upgrade your sensors from the old CS1-M / DS1-M switches to the CMSG / DMSG / EMSG family.
The 75 mm adjust code provides a usable stroke window of 425-500 mm. The full force set is 402/346/563 N and 82 kgf max.
