This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the drop-in replacement MBLJ40X200-50S, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MALJ40X200-50-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-50-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 150 to 200 mm. This model is discontinued — the drop-in replacement is the MBLJ40X200-50-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-50-S
The AirTAC MALJ40X200-50-S is a discontinued double-acting, adjustable-stroke mini cylinder. The exact drop-in replacement is the MBLJ40X200-50-S, matching the 40mm bore, 200mm stroke, G1/4 port, and 50mm adjuster. This rear-screw stopper lets you trim the end position, creating a usable stroke window of 150-200mm without external stops. Delivering 628N push and 528N pull at 0.5 MPa, it suits robust tasks.
The -S magnet on this MALJ works with CS1-M/DS1-M switches, while the MBLJ replacement upgrades to CMSG/DMSG/EMSG sensors. The MALJ features threaded covers and a fixed rubber bumper; the MBLJ uses a riveted rolling-packed body. Remember that the adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air pressure.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-50-S Is Used
Injection Mold Ejection
Dial the 150-200mm window to time plastic part ejection perfectly, using the 628N push force to safely strip parts without damaging the mold face.
PCB Depaneling Saw
Set the exact blade retreat depth on an automated PCB depaneling saw, preventing over-travel while relying on the fixed rubber bumper to soften the end impact.
Pneumatic Press Brake
Fine-tune the bending depth on a light-gauge sheet metal press brake, adjusting the stopper on the fly for different flange lengths without swapping hardware.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-50-S with MBLJ40X200-50-S
To replace the MALJ40X200-50-S, install the MBLJ40X200-50-S. Confirm the 40mm bore, 200mm stroke, 50mm adjust code, G1/4 port, PT threads, and FA/LB mounting (no back cover or SDB). The -S magnet means a sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. The rear adjuster is a travel stop, not a lock.
For sizing, step down to a 32mm bore (402N push @0.5 MPa) for lighter loads, or step up if you need more force. At 200mm stroke, watch rod side-loading; a 16mm rod resists bending but ensure guide alignment to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ40X200-50-S (same bore/stroke/adjust)
- ✓ Same 150–200 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 MBLJ40X200-50-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-50-S FAQ
Yes, the MALJ40X200-50-S is discontinued. The exact drop-in replacement is the MBLJ40X200-50-S, matching the 40mm bore, 200mm stroke, 50mm adjuster, G1/4 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M switches.
At 0.5 MPa, the push force is 628N and the pull force is 528N. At 0.7 MPa, push is 880N, with a maximum force of 128kgf at 1.0 MPa. The 50mm adjuster creates a usable stroke window of 150-200mm. The adjuster is a travel stop, not a lock; it will not hold a load without continuous air pressure.
