This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X310CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X310CA 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 MAL40X310CA (Discontinued) -> MBL40X310CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 310mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X310CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X310CA is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 310mm stroke. It delivers 628N push and 528N pull at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The exact drop-in replacement is the MBL40X310CA, which matches the force, port, and CA pivot mounting perfectly. You should order the MBL equivalent for new builds.
This legacy unit features a CA pivot back cover designed to swing on a pin for arcing loads, which is critical for this 310mm stroke length. The original MAL body used threaded front and back covers, whereas the current MBL replacement uses a riveted rolling-packed body. Because this SKU lacks an -S magnet, it cannot accept a position sensor. The internal fixed rubber bumper softens end-of-stroke impacts, but if you need adjustable air cushioning, you must step up to the MBLC variant on the current line.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X310CA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X310CA 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 pivoting cardboard folding arm on a packaging line, using the CA clevis to accommodate the arc of the 310mm stroke while delivering 628N push at 0.5MPa.
Actuates a fabric take-up roller assembly where the long 310mm travel and 528N pull force are required to draw material continuously without stalling.
Extends a 40mm bore physical stop gate to block incoming pallets on a gravity roller conveyor, relying on the fixed rubber bumper to absorb the 880N impact at 0.7MPa.
To replace the MAL40X310CA, order the MBL40X310CA. Confirm your 40mm bore, 310mm stroke, G1/4 port, and PT thread are correct. The CA pivot back cover is retained on the new MBL, ensuring your existing clevis pin mounting aligns perfectly. Since this SKU has no -S magnet, it cannot support a sensor; if you need position detection, specify an MBL40X310SCA and note that the modern MBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M/DS1-M. If you need adjustable end-cushioning to handle the kinetic energy of this long stroke, choose the MBLC40X310CA instead of the standard MBL.
For sizing flexibility, the next size down is the 32mm bore (402N push at 0.5MPa), and the next size up is the 50mm profile cylinder (not available in this mini round series). At 310mm of stroke, the 16mm carbon-steel rod is highly susceptible to side-load bending; you must use an external guide rail or rely fully on the CA pivot bracket to prevent rod deflection. A plain cylinder does not hold its load when air is lost, so install a pilot-operated check valve if drift is unacceptable.
Upgrade checklist
Yes, the MAL40X310CA is discontinued. The exact drop-in replacement is the MBL40X310CA, which offers the same 40mm bore, 310mm stroke, G1/4 port, and CA pivot mounting. The MBL uses a riveted rolling-packed body instead of the older threaded covers, but all performance ratings remain identical.
At 0.5MPa it provides 628N push and 528N pull; at 0.7MPa it provides 880N push, with a maximum theoretical force of 128kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; you must order an S-suffix model and use CMSG/DMSG/EMSG switches on the MBL replacement.
