This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X175-75-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X175-75-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 MALJ40X175-75-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-75-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 100 to 175 mm. This model is discontinued — the drop-in replacement is the MBLJ40X175-75-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-75-S
The AirTAC MALJ40X175-75-S is a discontinued double-acting single-rod cylinder with a 40mm bore and 175mm stroke. It features a rear screw stopper that lets you trim the end position by up to 75mm, creating a usable travel window of 100-175mm. This 40mm bore delivers 628N of push force at 0.5MPa. The exact drop-in replacement is the MBLJ40X175-75-S, matching the bore, stroke, adjuster, and G1/4 port.
This SKU includes a magnet (-S) for position sensing, using the legacy CS1-M or DS1-M switches; the MBLJ upgrade transitions to CMSG/DMSG/EMSG sensors. The original MALJ uses threaded covers, whereas the MBLJ replacement 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. End impact is softened by a fixed rubber bumper, as there is no adjustable air cushion.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-75-S Is Used
Palletizer Push-off
Dialing the 100-175mm window lets a palletizer push-off arm tune its reach for varying pallet widths without adding external stops, using the 628N push force to clear heavy boxes.
Bending Press Depth Stop
A small bending press uses the 75mm rear adjuster to set precise material forming depths on the fly, preventing over-travel of the 16mm rod while maintaining consistent 880N force at 0.7MPa.
Injection Mold Ejector
An injection molding line relies on the -S magnet and CS1-M switches to confirm ejection strokes, trimming up to 75mm to accommodate different mold depths without swapping the whole cylinder.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-75-S with MBLJ40X175-75-S
To replace the MALJ40X175-75-S with the MBLJ40X175-75-S, confirm the 40mm bore, 175mm stroke, 75mm adjust code, PT G1/4 port, and M12x1.25 rod-end thread. Mounting is limited to Basic, FA, or LB (no back-cover or SDB codes apply). Because this unit has the -S magnet, you must update your sensing kit from the older CS1-M/DS1-M to the MBLJ's CMSG/DMSG/EMSG switches. Remember the rear screw is a travel stop, not a lock, so an external lock is required to hold loads safely without air.
For sizing flexibility, the next size down is the 32mm bore (providing 402N push at 0.5MPa), and there is no larger standard MALJ bore above 40mm. At 175mm stroke, the 16mm carbon-steel rod is highly susceptible to side-load bending; ensure your mounting guides absorb lateral forces to prevent rod damage.
Upgrade checklist
- ✓ Order the MBLJ40X175-75-S (same bore/stroke/adjust)
- ✓ Same 100–175 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 MBLJ40X175-75-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-75-S FAQ
Yes, the MALJ40X175-75-S is discontinued. The exact drop-in replacement is the MBLJ40X175-75-S, which matches the 40mm bore, 175mm stroke, 75mm adjust code, and G1/4 port. You will need to upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG, and note the MBLJ uses a riveted body instead of threaded covers.
The 40mm bore provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The 75mm rear adjuster allows you to trim the stroke, creating a usable travel window from 100mm to 175mm. The adjuster acts only as a travel stop, not a lock, and end impact is absorbed by a fixed rubber bumper.
