This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X160-30-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X160-30-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 MALJ40X160-30-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-30-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 130 to 160 mm. This model is discontinued — the drop-in replacement is the MBLJ40X160-30-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-30-S
The AirTAC MALJ40X160-30-S is a discontinued double-acting single-rod cylinder with a 40mm bore and 160mm stroke. The -30 adjust code provides a usable travel window of 130-160mm. It delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X160-30-S, matching the bore, stroke, adjuster, G1/4 port, and mounting.
This SKU features a -S magnet for CS1-M or DS1-M switches; the MBLJ upgrade shifts to CMSG, DMSG, or EMSG sensors. The original MALJ uses threaded covers, while the MBLJ uses a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock, so it cannot 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 MBLJ40X160-30-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|

| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X160-30-S matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-30-S Is Used
PCB Router Depth Stop
Dial the 130-160mm window to set exact Z-axis reach on a PCB depaneling router. The 628N push force firmly holds the spindle carriage without deflecting during the routing pass.
Aluminum Extrusion Press
Fine-tune the end position when clamping 40mm aluminum profiles in a cutting cell. The rear stopper lets operators adjust reach by up to 30mm without machining new mount plates.
Carton Flap Folder
Time the stroke on a packaging line folding heavy double-wall carton flaps. The fixed rubber bumper absorbs the repeated 880N impact at 0.7MPa without bouncing the load.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-30-S with MBLJ40X160-30-S
To replace the MALJ40X160-30-S with the MBLJ40X160-30-S, confirm the 40mm bore, 160mm stroke, 30mm adjust code, PT G1/4 port, and FA or LB mounting (no back cover or SDB). Swap the CS1-M or DS1-M sensors for CMSG, DMSG, or EMSG switches. Remember the adjuster sets the end position but does not lock the load.
For sizing, if you need less force, step down to the 32mm bore which provides 402N push at 0.5MPa. If you need more power, there is no larger MALJ bore, so you would need to step up to a 50mm standard cylinder for higher force. At 160mm stroke, minimize side-load on the 16mm rod to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ40X160-30-S (same bore/stroke/adjust)
- ✓ Same 130–160 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 MBLJ40X160-30-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-30-S FAQ
Yes, the MALJ40X160-30-S is discontinued. The exact drop-in replacement is the MBLJ40X160-30-S, matching the 40mm bore, 160mm stroke, 30mm adjuster, and G1/4 port. You must upgrade your sensors from the old CS1-M or DS1-M to the CMSG, DMSG, or EMSG family.
The 40mm bore provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum force of 128kgf at 1.0MPa. The -30 adjust code lets you trim the 160mm stroke at the rear, creating a usable travel window of 130-160mm. The adjuster is a travel stop, not a lock.
