This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X275-75-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X275-75-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).

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-75-S
The AirTAC MALJ40X275-75-S is a discontinued double-acting, single-rod adjustable-stroke mini cylinder. It features a 40mm bore, a 275mm stroke, and a 75mm rear adjuster, yielding a usable travel window of 200-275mm. It delivers 628N push and 528N pull force at 0.5MPa. The exact drop-in replacement is the MBLJ40X275-75-S, matching the bore, stroke, adjuster, G1/4 port, and force.
This SKU includes a magnet (-S) for legacy CS1-M/DS1-M switches; the MBLJ upgrade moves to CMSG/DMSG/EMSG sensors. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ uses a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-75-S Is Used
Injection Mold Ejector
Dial the 200-275mm travel window to strike an injection mold ejector pin precisely, using the 628N push force at 0.5MPa without adding external stopper blocks.
Carton Flap Folder
Fine-tune the 275mm reach on a packaging line flap-folder; the fixed rubber bumper softens the end impact while the rear screw sets the exact fold depth.
Pneumatic Press Depth Stop
Set a specific 200mm pressing depth for light-duty assembly pins, leveraging the 880N push at 0.7MPa while relying on the stopper to prevent over-travel.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-75-S with MBLJ40X275-75-S
To replace the MALJ40X275-75-S, order the exact drop-in MBLJ40X275-75-S. Confirm the 40mm bore, 275mm stroke, 75mm adjust code, PT G1/4 port, and M12x1.25 rod-end thread. Mounting is FA or LB only (no back cover or SDB). The -S magnet means a sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. The rear adjuster is a travel stop, not a lock.
If sizing force, the next size down is the 32mm bore (402N push at 0.5MPa), and the next size up is beyond this series. At 275mm stroke, the 16mm rod is prone to bending under side loads; guide the load externally to prevent rod distortion.
Upgrade checklist
- ✓ Order the MBLJ40X275-75-S (same bore/stroke/adjust)
- ✓ Same 200–275 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 MBLJ40X275-75-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X275-75-S FAQ
Yes, the MALJ40X275-75-S is discontinued. The exact drop-in replacement is the MBLJ40X275-75-S, matching the 40mm bore, 275mm stroke, 75mm adjuster, G1/4 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design and switches sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 75mm rear adjuster creates a usable stroke window of 200-275mm. The full force spec for the 40mm bore is 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The adjuster is a travel stop, not a lock.
