AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X175-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X175-10 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).

The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10 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 165 to 175 mm. This model is discontinued — the drop-in replacement is the MBLJ40X175-10.
The AirTAC MALJ40X175-10 is a discontinued double-acting single-rod cylinder with a 10mm rear stroke adjuster, yielding a usable travel window of 165-175mm. It delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X175-10, matching the 40mm bore, 175mm stroke, and G1/4 port.
This SKU lacks a magnet (-S), so it cannot accept a position sensor. Unlike the threaded covers on this MALJ, the MBLJ replacement uses a riveted rolling-packed body. The rear adjuster is a travel stop to fine-tune depth, not a lock to hold a load without live air. End impact is softened by a fixed rubber bumper, as there is no air cushion.

The rear adjuster is a travel stop, not a lock — it sets the end position but does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ40X175-10 carries the same ratings.

Single-rod force, same as a standard MAL of this bore. The MBLJ40X175-10 matches these values.

Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Dial in the 165-175mm window to seat bronze bearings precisely without bottoming out, using the 628N push force at 0.5MPa for consistent insertion.
Fine-tune the 10mm rear stop to adapt plastic sheet depth on a forming press, ensuring the 16mm rod hits the exact mold height every cycle.
Adjust the end position to set routing depth limits on an automated CNC router, leveraging the fixed rubber bumper to soften the repeated end impact.
To replace this MALJ40X175-10, order the MBLJ40X175-10. Confirm the 40mm bore, 175mm stroke, 10mm adjust code, G1/4 port, PT thread, and Basic/FA/LB mounting (no back cover or SDB allowed). Since this SKU has no magnet, you lose sensors entirely; if you need position detection, step up to an MBLJ-S variant which uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
If you need to size either direction: stepping down to a 32mm bore drops thrust to 402N push at 0.5MPa, while stepping up is not available as 40mm is the largest MALJ bore. For any stroke approaching 300mm, be mindful of rod bending under side loads. Remember the adjuster sets end position but does not hold load without air pressure.
Upgrade checklist
Yes, the MALJ40X175-10 is discontinued. The exact drop-in replacement is the MBLJ40X175-10, matching the 40mm bore, 175mm stroke, 10mm adjuster, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original 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 -10 code means the rear screw trims up to 10mm of travel, creating a 165-175mm usable window. It acts only as a travel stop and does not hold load without air.
