This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X850-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X850-CA 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-CA (Discontinued) -> MBL40X850-CA 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-CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X850-CA is a discontinued double-acting aluminum mini round cylinder with an 850 mm stroke. Because 850 mm exceeds the 500 mm maximum standard stroke, this unit was produced as a non-standard, made-to-order configuration. Delivering 628 N of push force at 0.5 MPa, it uses a G1/4 port and a Ø16 mm carbon-steel rod with 20 um hard chrome plating. The CA back cover provides a pivot clevis, allowing the body to swing on a pin to absorb arcing loads.
AirTAC replaced this legacy unit with the MBL40X850-CA, a drop-in upgrade retaining the exact bore, stroke, output force, port size, and CA mounting. The obsolete MAL relied on threaded front and back covers, whereas the current MBL features a riveted rolling-packed body. Furthermore, this specific SKU lacks a -S magnet, meaning it cannot accept a position sensor. The MAL series uses a fixed rubber bumper for end-of-stroke deceleration; if your application requires an adjustable air cushion, you must step up to the MBLC variant on the current line.

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

The MBL40X850-CA 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.

Actuates a swinging diverter gate on a packaging conveyor, using the CA pivot to accommodate the arc of the 850 mm stroke as it reroutes heavy cardboard cartons.
Pushes raw hex bar stock through the spindle of a CNC lathe, relying on the 628 N push force at 0.5 MPa to overcome collet drag over the extended 850 mm travel.
Raises a lightweight fiber drum 850 mm between floor levels, where the fixed rubber bumper safely softens the end-of-stroke impact without requiring adjustment.
To replace the MAL40X850-CA, order the MBL40X850-CA, confirming the G1/4 port, PT thread, and CA pivot clevis. Since this 850 mm unit lacks a -S magnet, it cannot support a position sensor; if you need rod detection, order an MBL40X850-S-CA and migrate to the modern CMSG, DMSG, or EMSG switch family, as the older CS1-M and DS1-M sensors are obsolete. The fixed rubber bumper is not an adjustable cushion, nor does it hold the load if air pressure drops—the rod will drift. For position holding, add an external rod lock or a pilot-operated check valve.
At 850 mm, the 16 mm rod is highly susceptible to side-load bending and buckling; you must use the CA pivot mounting or an external guide rail to prevent premature seal failure. For sizing flexibility, stepping down to the 32 mm bore yields 402 N of push at 0.5 MPa, while stepping up to the larger 50 mm profile cylinder is required if you exceed the 128 kgf maximum theoretical force of this 40 mm bore.
Upgrade checklist
Yes, the MAL40X850-CA is discontinued. The exact drop-in replacement is the MBL40X850-CA, which matches the 40 mm bore, 850 mm stroke, 128 kgf max force, G1/4 port, and CA pivot mounting. The MBL upgrades the body to a riveted rolling-packed design instead of the older threaded covers.
At 0.5 MPa, the 40 mm bore provides 628 N of push force and 528 N of pull force; at 0.7 MPa, it delivers 880 N of push force, with a maximum theoretical output of 128 kgf at 1.0 MPa. The MAL uses a fixed rubber bumper for end-of-stroke deceleration; it is not an adjustable cushion. If you need adjustable air cushioning, you must use the current MBLC series.
