This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X160-50-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X160-50-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 MALJ40X160-50-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-50-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 110 to 160 mm. This model is discontinued — the drop-in replacement is the MBLJ40X160-50-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-50-S
The AirTAC MALJ40X160-50-S is a discontinued 40mm bore, double-acting mini cylinder with a 160mm stroke and a 50mm rear adjustable stroke stopper. This yields a usable end-position window of 110-160mm. The bore delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X160-50-S, matching the G1/4 port, M12x1.25 rod thread, and 128kgf max force.
The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Upgrading to the MBLJ40X160-50-S changes the sensor family from the older CS1-M/DS1-M to CMSG/DMSG/EMSG, and the body construction from threaded covers to a riveted rolling-packed body. A fixed rubber bumper softens end impact, though this is not an adjustable 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 MBLJ40X160-50-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-50-S Is Used
CNC Lathe Chuck Open/Close
Dialing the 110-160mm reach prevents over-travel on varying bar stock lengths, using the 880N push at 0.7MPa to actuate the chuck lever safely.
PCB Depaneling Saw Stop
Sets a precise depth stop for the cutting blade. The 50mm rear adjustment trims the cut depth without adding external physical stops to the saw carriage.
Pallet Wrap Turntable Index
Tunes the push-off stroke for different pallet sizes. The fixed rubber bumper absorbs the end impact of the 16mm rod during fast 30-800mm/s cycles.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-50-S with MBLJ40X160-50-S
To replace the MALJ40X160-50-S, order the drop-in MBLJ40X160-50-S. Confirm the 40mm bore, 160mm stroke, 50mm adjust code, G1/4 port, and FA/LB mounting (no back cover or SDB). The -S magnet requires switching from CS1-M/DS1-M to CMSG/DMSG/EMSG switches. Remember the adjuster is a stop, not a lock.
For sizing flexibility, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up is not available as 40mm is the largest MALJ bore. At 160mm stroke, be mindful of rod-bending under side loads; keep the load guided to prevent cylinder damage.
Upgrade checklist
- ✓ Order the MBLJ40X160-50-S (same bore/stroke/adjust)
- ✓ Same 110–160 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 MBLJ40X160-50-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X160-50-S FAQ
Yes, the MALJ40X160-50-S is discontinued. The exact drop-in replacement is the MBLJ40X160-50-S, which matches the 40mm bore, 160mm stroke, 50mm adjust code, G1/4 port, and 128kgf max force. You must upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG, as the new body uses a riveted rolling-packed construction instead of threaded covers.
The full figure set is 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The 50mm rear adjuster provides a usable stroke window of 110-160mm. The adjuster acts only as a travel stop and does not lock the load without continuous air pressure.
