This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X100-100-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X100-100-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 MALJ40X100-100-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-100-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 0 to 100 mm. This model is discontinued — the drop-in replacement is the MBLJ40X100-100-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-100-S
The AirTAC MALJ40X100-100-S is a discontinued 40mm bore, double-acting single-rod mini cylinder with a rear adjustable stroke stopper. It trims up to 100mm at the rear, giving a usable end-position window of 0-100mm. The 16mm carbon-steel rod delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X100-100-S, matching the G1/4 port, M12x1.25 rod thread, and 128kgf max force.
This SKU includes a magnet for position sensing. The older MALJ uses CS1-M or DS1-M switches, while the MBLJ upgrade moves to CMSG, DMSG, or EMSG sensors. The MALJ features threaded covers and a fixed rubber bumper; it has no adjustable air cushion. The rear adjuster sets the travel end point but does not hold the load without live air pressure, so fit an external lock for held loads.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-100-S Is Used
Variable Depth Drilling Jig
Dial in the exact 0-100mm reach on a multi-spindle wood drilling head. The 628N push force holds the block firmly against the stop while the rubber bumper absorbs the end impact.
Adjustable Carton Sealing Press
Set precise flap compression heights on a packaging line. The 880N push at 0.7MPa crushes corrugated flaps flat, and the rear screw lets you tune the depth without adding external stops.
Pneumatic Rivet Squeezer
Control the squeeze gap on a yoke riveter for different grip-length rivets. The 16mm rod provides rigid force transfer, and the M12x1.25 thread mounts the tooling firmly.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-100-S with MBLJ40X100-100-S
To replace the MALJ40X100-100-S, order the MBLJ40X100-100-S. Confirm the 40mm bore, 100mm stroke, 100mm adjust code, PT/G1/4 port, and M12x1.25 rod thread. Mounting is FA or LB only; there is no back-cover or SDB option. The -S magnet means you must upgrade your switches from the old CS1-M/DS1-M to the new CMSG/DMSG/EMSG family. Remember the adjuster is a travel stop, not a lock.
If sizing down, the 32mm bore neighbour gives 402N push at 0.5MPa. If sizing up, 40mm is the largest MALJ bore, so that is your maximum option. For this 100mm stroke, side-load and rod-bending forces are moderate, but ensure rigid guide alignment to avoid seal wear.
Upgrade checklist
- ✓ Order the MBLJ40X100-100-S (same bore/stroke/adjust)
- ✓ Same 0–100 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 MBLJ40X100-100-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-100-S FAQ
Yes, the MALJ40X100-100-S is discontinued. The exact drop-in replacement is the MBLJ40X100-100-S, which matches the 40mm bore, 100mm stroke, 100mm adjust code, G1/4 port, and 128kgf max force. The MBLJ upgrades the body to a riveted rolling-packed design and requires CMSG/DMSG/EMSG sensors instead of the old CS1-M/DS1-M.
The 100mm adjust code lets you trim the rear travel by up to 100mm, giving a usable stroke window of 0-100mm. The full force set 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.
