This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X250-40, 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 MALJ32X250-40
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X250-40 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 210 to 250 mm. This model is discontinued — the direct replacement is the MBLJ32X250-40.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X250-40
The AirTAC MALJ32X250-40 is a discontinued double-acting double-rod mini cylinder featuring a rear adjustable stroke stopper. By trimming up to 40 mm at the rear screw, it provides a usable end-position window of 210-250 mm.
The direct replacement is the MBLJ32X250-40, matching the 32 mm bore, 250 mm stroke, 40 mm adjust code, G1/8 port, and force. Upgrading brings a riveted rolling-packed body instead of the older threaded covers. Because this SKU lacks the -S magnet, it cannot accept a position sensor; the -S version uses CS1-M/DS1-M switches, while the new MBLJ uses CMSG/DMSG/EMSG sensors. The adjuster is a travel stop, not a lock, so it cannot hold a load without live air.

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 MBLJ32X250-40 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 MBLJ32X250-40 matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X250-40 Is Used
Carton Flap Folder
Fine-tune the rear stopper to 230 mm so the rod ends at the exact height to fold heavy corrugated flaps, using the 346 N pull to retract smoothly without overtravel.
Pallet Wrapper Film Cut
Set the end position to 210 mm to cleanly sever stretch film against a fixed blade, leveraging the fixed rubber bumper to soften the 563 N impact at 0.7 MPa.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X250-40 with MBLJ32X250-40
To replace the MALJ32X250-40 with the MBLJ32X250-40, confirm the 32 mm bore, 250 mm stroke, 40 mm adjust code, PT G1/8 port, M10x1.25 rod thread, and FA/LB mounting (no back cover or SDB). Remember the adjuster sets end position but does not hold load without air. At 250 mm stroke, mind rod side-load and bending on long extensions.
Upgrade checklist
- ✓ Order the MBLJ32X250-40 (same bore/stroke/adjust)
- ✓ Same 210–250 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 MBLJ32X250-40 instead of this discontinued model.
