This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X20-20S, 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).
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X20-20-S

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X20-20-S
The AirTAC MALJ32X20-20-S is a discontinued double-acting double-rod mini cylinder with a rear adjustable stroke stopper. The direct replacement is the MBLJ32X20-20-S, matching the 32mm bore, 20mm stroke, G1/8 port, and FA/LB mounting. This SKU provides a usable end-position window of 0-20mm.
The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Impact is softened by a fixed rubber bumper, as there is no adjustable air cushion. The -S magnet on this MALJ works with CS1-M / DS1-M switches, while the MBLJ replacement upgrades to CMSG / DMSG / EMSG sensors and uses a riveted rolling-packed body instead of threaded covers.

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 MBLJ32X20-20-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 MBLJ32X20-20-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X20-20-S Is Used
Connector Pin Insertion Depth
Trim the stroke down to 5mm to seat Molex connector pins into housings, preventing damage to the 12mm rod while relying on the fixed rubber bumper to soften the end impact.
Thin Sheet Metal Edge Bender
Fine-tune the bending depth for light-gauge sheet metal enclosures, using the 346 N pull force to retract the forming tool precisely within the 0-20mm adjustment range.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X20-20-S with MBLJ32X20-20-S
To replace the MALJ32X20-20-S with the MBLJ32X20-20-S, confirm the 32mm bore, 20mm stroke, 20mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). The -S magnet requires a sensor family change from CS1-M / DS1-M to CMSG / DMSG / EMSG. The adjuster is a stop, not a load lock.
Upgrade checklist
- ✓ Order the MBLJ32X20-20-S (same bore/stroke/adjust)
- ✓ Same 0–20 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 MBLJ32X20-20-S instead of this discontinued model.
