This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X225-100-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X225-100-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 MALJ40X225-100-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 125 to 225 mm. This model is discontinued — the drop-in replacement is the MBLJ40X225-100-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100-S
The AirTAC MALJ40X225-100-S is a discontinued double-acting single-rod cylinder with a 40 mm bore, 225 mm stroke, and a 100 mm rear adjuster. This yields a usable travel window of 125-225 mm. It delivers 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X225-100-S, matching the G1/4 port, M12x1.25 rod thread, and force ratings.
This -S variant uses the older CS1-M / DS1-M magnet switches, whereas the MBLJ upgrade uses CMSG / DMSG / EMSG sensors. The original MALJ features threaded covers, while the MBLJ uses a riveted rolling-packed body. The rear screw is a travel stop to dial in depth, not a lock to hold a load without live air. Impact is softened by a fixed rubber bumper, as there is no air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100-S |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100-S Is Used
Injection Mold Ejection
Dials the exact 125-225 mm ejection reach for plastic parts, using the 628 N push force to clear the mold without over-traveling.
Pallet Dispenser Push-off
Trims the rear stop to push empty pallets precisely to a conveyor junction, preventing crashes on the 225 mm extension.
Packaging Flap Folding
Adjusts the end position on the fly to fold varying carton depths, relying on the fixed rubber bumper to absorb the impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100-S with MBLJ40X225-100-S
To replace this MALJ40X225-100-S with the MBLJ40X225-100-S, confirm the 40 mm bore, 225 mm stroke, 100 mm adjust code, PT G1/4 port, and FA or LB mounting (no back cover or SDB). Remember the adjuster sets the end position but does not hold the load. If sizing down, the 32 mm bore offers 402 N push at 0.5 MPa; if sizing up, 40 mm is the largest MALJ bore available. At 225 mm stroke, minimize side-load to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ40X225-100-S (same bore/stroke/adjust)
- ✓ Same 125–225 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 MBLJ40X225-100-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-100-S FAQ
Yes, the MALJ40X225-100-S is discontinued. The exact drop-in replacement is the MBLJ40X225-100-S, matching the 40 mm bore, 225 mm stroke, 100 mm adjuster, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet switches from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The usable adjustable window is 125-225 mm, set by the 100 mm rear travel stop. 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 of 128 kgf at 1.0 MPa. The adjuster is a stop, not a lock, and cannot hold a load without air pressure.
