This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X225-40-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X225-40-S in place of this model. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40-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 185 to 225 mm. This model is discontinued — the drop-in replacement is the MBLJ40X225-40-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40-S
The AirTAC MALJ40X225-40-S is a discontinued adjustable-stroke, double-acting single-rod mini cylinder. A rear screw lets you trim up to 40 mm, giving a usable end-position window of 185-225 mm. The 40 mm bore delivers 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X225-40-S, matching the bore, stroke, G1/4 port, and mounting.
This SKU includes the -S magnet, which uses the older CS1-M / DS1-M switches; the MBLJ replacement upgrades to CMSG / DMSG / EMSG sensors. The MALJ features threaded covers, while the MBLJ uses a riveted rolling-packed body. The 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 only by a fixed rubber bumper.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40-S Is Used
Printed Circuit Board Drill
Dial the 185-225 mm reach to set a precise depth for a multi-spindle PCB drill, using the 628 N push force to drive the spindle down without over-traveling.
Carton Flap Folder
Fine-tune the folding arm end position on a packaging line; the rear stop lets you adjust the 225 mm stroke by up to 40 mm to match varying carton heights without adding external stops.
Plastic Injection Mold Guard
Set the exact retracted position for a safety door actuator; the fixed rubber bumper absorbs the end impact while the stopper dials in the required clearance.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40-S with MBLJ40X225-40-S
Replace this MALJ40X225-40-S directly with the MBLJ40X225-40-S. Confirm the 40 mm bore, 225 mm stroke, 40 mm adjust code, PT G1/4 port, and M12x1.25 rod thread. Mounting is FA or LB only, as there is no back cover or SDB option. The -S magnet requires changing from CS1-M / DS1-M to CMSG / DMSG / EMSG switches. Remember the adjuster is a stop, not a lock.
For sizing, step down to the 32 mm bore (402 N push @0.5 MPa) if your load is lighter, or step up if you need more force—though 40 mm is the largest MALJ bore. At 225 mm stroke, support the rod to prevent bending under side-load.
Upgrade checklist
- ✓ Order the MBLJ40X225-40-S (same bore/stroke/adjust)
- ✓ Same 185–225 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 MBLJ40X225-40-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-40-S FAQ
Yes, the MALJ40X225-40-S is discontinued. The exact drop-in replacement is the MBLJ40X225-40-S, which matches the 40 mm bore, 225 mm stroke, 40 mm adjust code, G1/4 port, and mounting. You will only need to change from CS1-M / DS1-M sensors to CMSG / DMSG / EMSG switches.
The 40 mm bore provides 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The 40 mm adjust code lets you trim the 225 mm stroke at the rear, creating a usable window of 185-225 mm.
