This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X160-20-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X160-20-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 MALJ40X160-20-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-20-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 140 to 160 mm. This model is discontinued — the drop-in replacement is the MBLJ40X160-20-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-20-S
The AirTAC MALJ40X160-20-S is a discontinued double-acting single-rod cylinder with a 40 mm bore and a 160 mm stroke. Its rear adjuster trims up to 20 mm, giving a usable end-position window of 140-160 mm. It delivers 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X160-20-S, matching the bore, stroke, force, G1/4 port, and mounting.
This SKU includes a magnet (-S) for CS1-M / DS1-M switches; the MBLJ upgrade moves to CMSG / DMSG / EMSG sensors. The original MALJ uses threaded covers, while the MBLJ 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 air cushion.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-20-S Is Used
Pallet Dispenser Push-off
Dials the exact 140-160 mm push-off depth for empty pallet stacks using 628 N of force, allowing fine-tuning without remounting the cylinder.
Printed Circuit Board Test Nest
Adjusts the travel stop to set precise probe descent on an ICT fixture, preventing over-travel on changing board thicknesses.
Woodworking Door Clamp
Trims the rear position by up to 20 mm to square cabinet doors during gluing, using the fixed rubber bumper to soften the clamp impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-20-S with MBLJ40X160-20-S
To replace the MALJ40X160-20-S, use the MBLJ40X160-20-S. Confirm the 40 mm bore, 160 mm stroke, 20 mm adjust code, G1/4 PT thread, and FA/LB mounting (no back cover or SDB). The -S magnet requires changing from CS1-M / DS1-M to CMSG / DMSG / EMSG sensors. The adjuster is a stop, not a lock; add an external lock for held loads.
For sizing, step down to the 32 mm bore (402 N push @0.5 MPa) if you need less force, or step up to a larger standard bore if your load exceeds 628 N. At 160 mm stroke, keep the rod side-load minimal to prevent bending, as there is no air cushion to absorb impact.
Upgrade checklist
- ✓ Order the MBLJ40X160-20-S (same bore/stroke/adjust)
- ✓ Same 140–160 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 MBLJ40X160-20-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-20-S FAQ
Yes, the MALJ40X160-20-S is discontinued. The exact drop-in replacement is the MBLJ40X160-20-S, matching the 40 mm bore, 160 mm stroke, 20 mm adjust code, G1/4 port, and mounting. You will need to upgrade the magnet sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The usable stroke window is 140-160 mm (160 mm stroke minus the 20 mm adjust code). The 40 mm bore provides 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum force of 128 kgf at 1.0 MPa. The rear screw is a travel stop, not a lock.
