This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the drop-in replacement MBLJ40X100-10S, 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 MALJ40 Adjustable Mini Cylinder MALJ40X100-10-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-10-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 90 to 100 mm. This model is discontinued — the drop-in replacement is the MBLJ40X100-10-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-10-S
The AirTAC MALJ40X100-10-S is a discontinued double-acting single-rod cylinder with a rear adjustable stroke stopper. It features a 40 mm bore, a 100 mm stroke, and a 10 mm adjuster, giving a usable end-position window of 90-100 mm. It delivers 628 N push and 528 N pull at 0.5 MPa, with a fixed rubber bumper absorbing end impacts. The exact drop-in replacement is the MBLJ40X100-10-S, matching bore, stroke, adjust code, port, and mounting.
This SKU includes the -S magnet for position sensing. The legacy MALJ works with CS1-M / DS1-M switches, while the MBLJ replacement upgrades to CMSG / DMSG / EMSG sensors. The MALJ uses threaded covers, whereas the modern MBLJ features a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-10-S Is Used
Injection Mold Ejector
Dial the 90-100 mm reach to strike an ejection pin precisely without resetting the mold platen, using 628 N push at 0.5 MPa to clear the part.
Tube Bending Stop
Set the exact 10 mm trim on a 100 mm stroke to halt a mandrel at the correct depth for complex pipe bends, preventing over-stretching of the tube.
PCB Drill Depth Stop
Fine-tune the downward travel window on a drilling head, ensuring the 16 mm rod stops cleanly before breaking through the back of the panel.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-10-S with MBLJ40X100-10-S
To replace the MALJ40X100-10-S, order the drop-in MBLJ40X100-10-S. Confirm the 40 mm bore, 100 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and FA or LB mounting (there is no back cover or SDB option). The -S magnet transfers over, but you must upgrade your CS1-M / DS1-M switches to the CMSG / DMSG / EMSG family. Remember the adjuster is a travel stop, not a lock.
For sizing both ways, step down to the 32 mm bore for 402 N push at 0.5 MPa, or step up if you need more force (40 mm is the largest MALJ bore). At 100 mm stroke, keep the rod guided to prevent side-load bending of the 16 mm rod.
Upgrade checklist
- ✓ Order the MBLJ40X100-10-S (same bore/stroke/adjust)
- ✓ Same 90–100 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 MBLJ40X100-10-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-10-S FAQ
Yes, the MALJ40X100-10-S is discontinued. The exact drop-in replacement is the MBLJ40X100-10-S, which matches the 40 mm bore, 100 mm stroke, 10 mm adjust code, G1/4 port, and mounting. You will need to upgrade your sensors from the older CS1-M / DS1-M to the CMSG / DMSG / EMSG family.
The usable adjustable window is 90-100 mm (100 mm stroke minus the 10 mm adjust code). The force figures are: 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 adjuster is a travel stop, not a lock, and does not hold load without air.
