This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X100-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X100-20 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 MALJ40X100-20
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-20 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 80 to 100 mm. This model is discontinued — the drop-in replacement is the MBLJ40X100-20.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-20
The AirTAC MALJ40X100-20 is a discontinued double-acting mini cylinder with a 40 mm bore and 100 mm stroke. The -20 adjust code lets you trim the rear end position by up to 20 mm, creating a usable stroke window of 80-100 mm. It delivers 628 N push and 528 N pull force at 0.5 MPa. The exact drop-in replacement is the MBLJ40X100-20, matching the bore, stroke, adjust code, and G1/4 port.
This SKU lacks the -S magnet, so it cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Upgrading to the MBLJ moves from threaded covers to a riveted rolling-packed body. If you ever need a sensor, the MBLJ uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M family. Impact is softened by a fixed rubber bumper, as there is no adjustable air cushion.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-20 Is Used
Press Fit Subassembly
Dialing the 80-100 mm window on a 628 N press cylinder lets you seat a bearing without bottoming out the rod mechanically.
Thermoforming Mold Stop
Trimming 20 mm off the 100 mm stroke sets a precise mold open distance, using the 880 N force at 0.7 MPa to hold the form.
Packaging Feed Gate
Adjusting the rear stopper changes the pusher reach for different carton depths without adding external collars to the 16 mm rod.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-20 with MBLJ40X100-20
To replace this MALJ40X100-20, order the MBLJ40X100-20. Confirm your 40 mm bore, 100 mm stroke, 20 mm adjust code, G1/4 port, PT thread, and FA/LB mounting. Because this SKU has no -S magnet, it cannot take a sensor; if your new MBLJ needs one, specify the -S option for CMSG/DMSG/EMSG switches. Remember the adjuster is a stop, not a lock. If sizing either way, stepping down to a 32 mm bore yields 402 N push at 0.5 MPa, while stepping up is unavailable as 40 mm is the largest MALJ bore.
Upgrade checklist
- ✓ Order the MBLJ40X100-20 (same bore/stroke/adjust)
- ✓ Same 80–100 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 MBLJ40X100-20 instead of this discontinued model.
