This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X150SCMLB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X150SCMLB in place of this model. The MBL replacement upgrades to a riveted rolling-packed body and the current CMSG / DMSG / EMSG sensor switches (the MAL used CS1-M / DS1-M).
The AirTAC AirTAC MAL40X150SCMLB (Discontinued) → MBL40X150SCMLB is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 150mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X150SCMLB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X150SCMLB is a discontinued double-acting aluminum mini round cylinder. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa, utilizing a Ø16 mm carbon-steel rod with a 20 µm hard chrome plating to resist wear. AirTAC replaced this legacy unit with the MBL40X150SCMLB, a drop-in alternative that matches the original 150 mm stroke, G1/4 port, and LB foot mounting. The MBL upgrades the threaded front and back covers to a riveted rolling-packed body for greater structural rigidity.
This specific SKU includes a built-in magnet (-S) for position sensing, meaning the older MAL works with legacy CS1-M or DS1-M reed switches. When upgrading to the MBL equivalent, you must update your sensors to the current CMSG, DMSG, or EMSG families. The cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts, but it cannot hold a load if air pressure drops. For applications needing adjustable end-cushioning, the current MBLC variant offers that feature, which the MAL lacked.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X150SCMLB produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Delivers 628 N of push force at 0.5 MPa to fold heavy corrugated cardboard flaps on continuous packaging lines, utilizing the 150 mm stroke to clear the box path during retraction.
Uses the 880 N push force at 0.7 MPa to positively eject dense plastic parts from small injection molds, where the LB foot mount provides a rigid base against sudden stripping forces.
Pushes lightweight tooling trays into staging position on a tight 150 mm stroke, where the round-end CM back cover and self-lubricating bearing guide handle frequent, short repetitive cycles.
To replace the MAL40X150SCMLB, order the MBL40X150SCMLB and verify your porting (PT tapered thread, G1/4) and the LB foot mounting pattern. Because this unit has the -S magnet, plan to swap out older CS1-M/DS1-M switches for modern CMSG/DMSG/EMSG sensors. If 628 N of push at 0.5 MPa is too much, step down to the 32 mm bore (402 N push); if you need more power, 40 mm is the largest standard MAL mini round bore available. At 150 mm of stroke, the small 16 mm rod has limited side-load tolerance, so ensure your LB foot mount allows rigid alignment or add an external guide. Remember that the rubber bumper softens impacts but does not lock the rod; use a pilot-operated check valve for position holding.
Upgrade checklist
Yes, the MAL40X150SCMLB is discontinued. The exact drop-in replacement is the MBL40X150SCMLB, which matches the 40 mm bore, 150 mm stroke, G1/4 port, LB foot mount, and CM round-end back cover. You just swap the cylinder and update your -S magnet sensors from the old CS1-M/DS1-M to the new CMSG/DMSG/EMSG family.
The MAL40X150SCMLB uses a G1/4 port and a Ø16 mm rod. At 0.5 MPa it provides 628 N push and 528 N pull force. At 0.7 MPa the push force is 880 N, and the maximum theoretical force is 128 kgf at 1.0 MPa.
