This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X300-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X300-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 MAL40X300-CA (Discontinued) → MBL40X300-CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 300mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X300-CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X300-CA is a discontinued double-acting aluminum mini round cylinder engineered for a 40 mm bore and 300 mm stroke. It delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa. AirTAC replaced this legacy unit with the MBL40X300-CA, a drop-in alternative retaining the exact same bore, stroke, output force, G1/4 port, and CA mounting interface. The original MAL design relies on threaded front and back covers fastened to the barrel, whereas the modern MBL body utilizes a riveted rolling-packed construction for equally robust performance.
This specific SKU features a CA pivot back cover, meaning it swings on a pin to absorb arcing loads rather than rigidly binding. Because this configuration lacks the -S magnet option, it cannot accept a position sensor. Internally, the piston relies on a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide that supports the 16 mm carbon-steel rod with 20 um hard-chrome plating.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X300-CA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The MBL40X300-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.

Drives a 300 mm stroke lever arm to position yarn guides, using the 628 N push force to maintain fabric tension while the CA pivot absorbs the lateral arc of the weaving mechanism.
Pushes corrugated cartons across a sorting belt where the 528 N pull force reliably retracts the 16 mm rod against friction over the 300 mm travel distance.
Acts as a 40 mm bore physical stop for incoming pallets, relying on the fixed rubber bumper to absorb the kinetic energy of arriving loads without damaging the clevis pin.
To replace the MAL40X300-CA, order the exact MBL40X300-CA. Confirm your 40 mm bore, 300 mm stroke, PT thread form, and the CA pivot back cover. Since this unit has no -S magnet, it cannot support a sensor; if you require position detection on the new unit, add the S suffix to the MBL and note that the legacy CS1-M / DS1-M switches are superseded by CMSG / DMSG / EMSG sensors. The MAL uses a fixed rubber bumper; if end-of-stroke shock is an issue in your application, step up to the MBLC variant on the current line for an adjustable air cushion.
For sizing flexibility, step down to the 32 mm bore (delivering 402 N push at 0.5 MPa) if your load is lighter, or step up if you need more force. Because the stroke is 300 mm, the 16 mm rod is susceptible to bending under lateral stress. Rely on the CA clevis to accommodate arcing trajectories, or install an external guide rail to prevent side-load damage. Note that a plain cylinder does not hold its position when air is lost; the bumper only softens impact, so add an external rod lock for suspended loads.
Upgrade checklist
Yes, the MAL40X300-CA is discontinued. The exact drop-in replacement is the MBL40X300-CA, which matches the 40 mm bore, 300 mm stroke, G1/4 port, and CA pivot mounting. The MBL upgrades the body to a riveted rolling-packed design but functions identically.
At 0.5 MPa it provides 628 N push and 528 N pull; at 0.7 MPa it pushes 880 N, with a theoretical maximum of 128 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor like the CS1-M or DS1-M.
