This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X850SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X850SU 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 MAL40X850SU (Discontinued) -> MBL40X850SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 850mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X850SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X850SU is a discontinued double-acting aluminum mini round cylinder. Built for a 40mm bore, it delivers 628N push and 528N pull at 0.5MPa, utilizing a G1/4 port and an 850mm made-to-order stroke. The exact drop-in replacement is the MBL40X850SU, matching the force, port, and stroke perfectly.
This legacy unit features a U flat-end back cover for rigid mounting and a built-in -S magnet. Upgrading to the MBL shifts the body from threaded covers to a riveted rolling-packed design, and the sensor family changes from the older CS1-M/DS1-M to the current CMSG/DMSG/EMSG switches. A fixed rubber bumper absorbs end-of-stroke impact, but it will not hold the load if air pressure drops.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X850SU carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The MBL40X850SU 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.

Uses the 628N push force at 0.5MPa to positively index empty pallets out of a vertical magazine onto a transfer line.
The 850mm stroke fully extends to push raw bar stock through the spindle, relying on the rigid U flat-end cover for alignment.
Deploys the long stroke to fold large corrugated box flaps, requiring an external guide to prevent rod deflection.
To replace the MAL40X850SU, order the MBL40X850SU. Verify your 40mm bore, 850mm non-standard stroke, G1/4 port, and PT thread. Because this SKU includes the -S magnet, you must upgrade your position sensing from the legacy CS1-M/DS1-M switches to the modern CMSG/DMSG/EMSG family used on the MBL. The U flat-end back cover provides a rigid rear mount.
If you need to step the force down, the 32mm bore neighbor offers 402N push at 0.5MPa. Stepping up is not possible as 40mm is the largest MAL mini round size. The 850mm stroke creates a high rod-bending moment; use an external guide rail to prevent side-load damage. Note that the fixed rubber bumper is not an adjustable cushion—upgrade to the MBLC series if end-cushioning is critical. A plain cylinder drifts when air is lost, so add an external rod lock for position holding.
Upgrade checklist
Yes, the MAL series is discontinued. The exact drop-in replacement is the MBL40X850SU. It shares the same 40mm bore, 850mm stroke, 628N push force at 0.5MPa, G1/4 port, and U flat-end mounting. You only need to update your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
At 0.5MPa, the 40mm bore provides 628N push and 528N pull. At 0.7MPa, push force is 880N. The theoretical maximum force is 128kgf at 1.0MPa. Operating pressure is 0.1-1.0MPa, speed is 30-800mm/s, and the 850mm stroke is a non-standard made-to-order length.
