This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X275CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X275CA 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 MAL40X275CA (Discontinued) -> MBL40X275CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 275mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X275CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X275CA is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces requiring substantial thrust. Delivering 628 N of push force and 528 N of pull force at 0.5 MPa, it operates at speeds of 30-800 mm/s. This legacy unit features a G1/4 port, a Ø16 mm carbon-steel rod with 20 um hard-chrome plating, and a PT tapered thread form. AirTAC ended the MAL series, so the exact drop-in replacement is the MBL40X275CA, matching the bore, stroke, force, port, and CA mounting.
This SKU includes a CA pivot back cover, swinging on a pin to absorb arcing loads, and lacks a magnet, meaning it cannot accept a position sensor. The legacy MAL uses a heterogeneous two-way grease-retaining seal alongside a self-lubricating front-cover bearing guide. In the upgrade to the MBL, the threaded front and back covers were replaced by a riveted rolling-packed body, retaining the same ratings while modernizing the assembly.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X275CA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X275CA 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.

Replacement mapping: MAL → MBL, MSAL → MSBL, MTAL → MTBL, MALD → MBLD, MALJ → MBLJ.
Pushes 20 kg pallets sideways at 0.5 MPa using 628 N of thrust, with the 275 mm stroke clearing the main conveyor belt.
Secures heavy cast iron blocks during machining, relying on the self-lubricating bearing guide to handle repetitive clamping cycles.
Folds large corrugated carton flaps on a packaging line, where the CA pivot absorbs the arcing motion as the flap closes.
To replace the MAL40X275CA, order the MBL40X275CA drop-in equivalent, confirming the 40 mm bore, 275 mm stroke, G1/4 port, PT thread, and CA pivot back cover. If your application requires an adjustable air cushion rather than the fixed rubber bumper found on this MAL, step up to the MBLC series on the current line. Since this SKU lacks the -S magnet, it cannot support a sensor; if position detection is needed, order an MBL with -S and note that the older CS1-M / DS1-M switches are replaced by CMSG / DMSG / EMSG sensors.
If you need to size the bore differently, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, while stepping up is not an option as 40 mm is the largest MAL mini round bore. Because the stroke is 275 mm, the 16 mm rod has limited side-load tolerance; use the CA clevis to articulate and prevent rod bending, or add an external guide. Note that a plain MAL/MBL does not hold its load when air is lost—the bumper softens the stroke end but is not a lock.
Upgrade checklist
Yes, the MAL40X275CA is discontinued. The exact drop-in replacement is the MBL40X275CA, offering the same 40 mm bore, 275 mm stroke, 628 N push force, G1/4 port, and CA pivot mounting. The MBL upgrades the body to a riveted rolling-packed design from the original threaded covers.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force reaches 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. It operates within a 0.1-1.0 MPa pressure range.
