This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X850-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X850-CM 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 MAL40X850-CM (Discontinued) → MBL40X850-CM 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 MBL40X850-CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X850-CM is a discontinued double-acting aluminum mini round cylinder with an 850 mm stroke. As a made-to-order non-standard stroke exceeding the 500 mm standard limit, it delivers a robust 628 N push force at 0.5 MPa. The exact drop-in replacement is the MBL40X850-CM, matching the 40 mm bore, output force, G1/4 port, and CM round-end back cover for a seamless retrofit.
This legacy unit features a carbon-steel rod with 20 um hard-chrome plating and a heterogeneous two-way seal that retains grease. The original MAL uses threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body. Because this specific SKU lacks an -S magnet, it cannot accept a position sensor. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X850-CM carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The MBL40X850-CM 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.

Drives a strapping head to eject wrapped pallets along a long 850 mm conveyor lane using 628 N of push force.
Extends to push full textile beams out of a winding machine, utilizing the CM round-end cover to accommodate slight angular misalignment.
Actuates a diverting arm across a wide package sorting belt, requiring the full 850 mm extension to reach the adjacent lane.
To replace this obsolete actuator, order the MBL40X850-CM. Verify your porting (PT tapered threads standard), the M12x1.25 rod-end thread, and the CM round-end back cover. Since this SKU has no -S magnet, it cannot support a sensor; if position detection is needed, order an MBL equivalent with an S suffix (which uses the modern CMSG/DMSG/EMSG switches instead of the legacy CS1-M/DS1-M). If you need adjustable air cushioning at the stroke ends, step up to the MBLC series, as the MAL only has a fixed rubber bumper.
For sizing flexibility, the next size down is the 32 mm bore (delivering 402 N push at 0.5 MPa), and the 40 mm bore is the largest available in this mini round family. An 850 mm stroke on a 16 mm rod creates a high buckling risk under side loads. You must use an external guide rail or pair this cylinder with a pivot mounting to prevent rod bending. Note that the bumper softens impact but does not hold the load if air pressure drops; use a pilot-operated check valve for position holding.
Upgrade checklist
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL40X850-CM. It provides the same 40 mm bore, 850 mm stroke, 628 N push force at 0.5 MPa, G1/4 port, and CM round-end cover. The MBL upgrades the body to a riveted rolling-packed design instead of the original threaded covers.
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa push increases to 880 N, with a theoretical maximum of 128 kgf at 1.0 MPa. The fixed rubber bumper only softens end-of-stroke impact; it does not hold the load if air is lost, so a separate rod lock or pilot check valve is required for position holding.
