This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X175-100-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X175-100-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 MALJ40X175-100-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-100-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 75 to 175 mm. This model is discontinued — the drop-in replacement is the MBLJ40X175-100-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-100-S
The AirTAC MALJ40X175-100-S is a discontinued double-acting, single-rod mini cylinder with a 40mm bore and a 175mm stroke. It provides a usable extension window of 75-175mm via its 100mm rear adjuster, delivering 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X175-100-S, matching your bore, stroke, port, and force.
This -S magnet SKU uses older CS1-M/DS1-M switches, while the MBLJ replacement upgrades to CMSG/DMSG/EMSG sensors. The original MALJ has threaded covers; the MBLJ uses 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. End impact is softened by a fixed rubber bumper, as there is no adjustable air cushion.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-100-S Is Used
Packaging Carton Flap Folding
Dial the 75-175mm stroke window to fold varying corrugated box flaps precisely, using the 628N push force without repositioning the cylinder mount.
Palletizing Depth Stop
Set a hard rear travel stop to vary product insertion depth on a 40mm bore assembly line, relying on the fixed rubber bumper to soften end impact.
Automotive Sub-Assembly Press
Trim the end position up to 100mm to seat bearings or pins in tight chassis jigs, switching from CS1-M to CMSG sensors on the MBLJ replacement.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-100-S with MBLJ40X175-100-S
To replace the MALJ40X175-100-S, install the MBLJ40X175-100-S. Confirm your 40mm bore, 175mm stroke, 100mm adjust code, G1/4 port, M12x1.25 rod thread, and PT thread form. Mounting is FA or LB only (no back cover or SDB). Your -S magnet sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. The rear adjuster is a travel stop, not a lock.
For sizing both ways: stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up to the 50mm bore (from the related MAL/MBL series) provides higher force. At 175mm stroke, support the rod end to prevent side-load bending.
Upgrade checklist
- ✓ Order the MBLJ40X175-100-S (same bore/stroke/adjust)
- ✓ Same 75–175 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 MBLJ40X175-100-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-100-S FAQ
Yes, the MALJ40X175-100-S is discontinued. The exact drop-in replacement is the MBLJ40X175-100-S, matching the 40mm bore, 175mm stroke, 100mm adjust code, G1/4 port, and force. The MBLJ upgrades the body to a riveted rolling-packed design and the -S magnet sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The usable stroke window is 75-175mm, set by trimming up to 100mm at the rear. The 40mm bore generates 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, and end impact is softened by a fixed rubber bumper.
