This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X200-75-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X200-75-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 MALJ40X200-75-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-75-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 125 to 200 mm. This model is discontinued — the drop-in replacement is the MBLJ40X200-75-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-75-S
The AirTAC MALJ40X200-75-S is a discontinued double-acting single-rod cylinder with a 40mm bore and 200mm stroke. The -75 adjust code lets you trim the rear end position by up to 75mm, creating a usable stroke window of 125-200mm. It delivers 628N push and 528N pull at 0.5MPa, uses a G1/4 port, and includes a -S magnet. The exact drop-in replacement is the MBLJ40X200-75-S.
This mini cylinder uses a fixed rubber bumper, meaning the adjustable stroke sets the travel stop but does not function as an air cushion. The rear adjuster is a travel stop, not a lock; it will not hold a load without live air pressure. For the upgrade, the older MAL threaded covers and CS1-M/DS1-M sensors are replaced by a riveted rolling-packed body and CMSG/DMSG/EMSG switches on the MBLJ.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-75-S Technical Specifications

| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
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 MBLJ40X200-75-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X200-75-S matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-75-S Is Used
PCB Router Depth Stop
Dial the 125-200mm window to set exact Z-axis plunge depth on a PCB depaneling router, using the 628N push force to maintain a consistent cut without crashing the spindle.
Aluminum Profile Clamping
Tune the retract distance on an aluminum extrusion cutting saw, adjusting the stroke by up to 75mm to clamp varying profile widths securely before the saw blade engages.
Carton Flap Folding
Fine-tune the actuation reach on a packaging line carton sealer, using the 528N pull force to fold flaps accurately on different box sizes without repositioning the cylinder mount.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-75-S with MBLJ40X200-75-S
To replace this MALJ40X200-75-S, install the MBLJ40X200-75-S. Confirm the 40mm bore, 200mm stroke, 75mm adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB). The -S magnet changes sensor families from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster remains a travel stop, not a lock.
For sizing, step down to the 32mm bore for 402N push at 0.5MPa, or step up to a larger standard body if you need more force than the 40mm's 628N. Because this 200mm stroke is relatively long, minimize side loads to prevent rod bending and seal wear.
Upgrade checklist
- ✓ Order the MBLJ40X200-75-S (same bore/stroke/adjust)
- ✓ Same 125–200 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 MBLJ40X200-75-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-75-S FAQ
Yes, the MALJ40X200-75-S is discontinued. The exact drop-in replacement is the MBLJ40X200-75-S, which matches the 40mm bore, 200mm stroke, 75mm adjust code, and G1/4 port. You will need to upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG switches.
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 -75 code means you can shorten the 200mm stroke at the rear screw by up to 75mm, giving a usable window of 125-200mm. This adjuster is a travel stop, not a lock.
