This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X300-100-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X300-100-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 MALJ40X300-100-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X300-100-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 200 to 300 mm. This model is discontinued — the drop-in replacement is the MBLJ40X300-100-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X300-100-S
The AirTAC MALJ40X300-100-S is a discontinued double-acting single-rod cylinder with a rear travel stopper. It gives a usable stroke window of 200-300 mm by trimming up to 100 mm at the rear screw. The 40 mm bore uses a G1/4 port and delivers 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X300-100-S.
This SKU includes a magnet (-S) for CS1-M or DS1-M switches. The MBLJ upgrade shifts to CMSG, DMSG, or EMSG sensors and replaces the original threaded covers with a riveted rolling-packed body. The fixed rubber bumper softens end impacts but provides no air cushioning. The rear adjuster sets the end position but is a travel stop, not a lock, so it will not hold a load without live air pressure.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X300-100-S Is Used
Thermoforming Press Ejection
Dials the exact 200-300 mm ejection reach for deep-draw plastic trays. The 628 N push force reliably strips formed sheets from molds without requiring custom spacers.
Printed Circuit Board Screening
Sets a precise squeegee stop depth on long-stroke solder paste printers. The rear stopper prevents the 16 mm rod from bottoming out, protecting fragile fixtures.
Automated Pallet Dispenser
Fine-tunes the pick position for varying empty pallet stacks in packaging lines. The 100 mm adjustment window accommodates height differences without swapping hardware.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X300-100-S with MBLJ40X300-100-S
To replace the MALJ40X300-100-S with the MBLJ40X300-100-S, confirm the 40 mm bore, 300 mm stroke, 100 mm adjust code, G1/4 port, PT thread, and FA or LB mounting. There is no back cover or SDB option. You must also change your CS1-M or DS1-M sensors to the CMSG, DMSG, or EMSG family. If you need to resize, stepping down to the 32 mm bore drops force to 402 N push at 0.5 MPa, while no larger bore exists in this mini series.
At 300 mm of stroke, the 16 mm carbon-steel rod is vulnerable to side-load bending. Keep the load guided to prevent rod damage. Because the adjuster is a stop and not a lock, add an external locking mechanism if the assembly must hold position during an air-loss event.
Upgrade checklist
- ✓ Order the MBLJ40X300-100-S (same bore/stroke/adjust)
- ✓ Same 200–300 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 MBLJ40X300-100-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X300-100-S FAQ
Yes, the MALJ40X300-100-S is discontinued. The exact drop-in replacement is the MBLJ40X300-100-S, which matches the 40 mm bore, 300 mm stroke, 100 mm adjust code, and G1/4 port. You will need to upgrade your switches from CS1-M or DS1-M to the CMSG, DMSG, or EMSG sensor family.
The force output is 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 100 mm adjuster is a travel stop that lets you shorten the end position, creating a usable stroke window of 200-300 mm. It does not hold the load without live air pressure.
