This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X55CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X55CA 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 MAL40X55CA (Discontinued) → MBL40X55CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 55mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X55CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X55CA is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 55mm stroke. It delivers a robust 628N push and 528N pull at 0.5 MPa, making it a compact powerhouse for heavy small-part actuation. AirTAC replaced this legacy unit with the MBL40X55CA, a drop-in upgrade matching the exact bore, stroke, 880N push at 0.7 MPa, G1/4 port, and CA pivot mounting.
This specific SKU features a CA pivot back cover that swings on a pin to absorb arcing rod paths, unlike rigid flat-end mounts. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for equal strength. Note that this non-magnet model cannot accept a position sensor; furthermore, end-of-stroke energy relies on a fixed rubber bumper rather than an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X55CA 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 MBL40X55CA 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.

| ×55 | Stroke length in mm. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBL uses CMSG/DMSG/EMSG). |
| CA / U / CM | Back cover: CA pivot, U flat-end or CM round-end. |
Replacement mapping: MAL → MBL, MSAL → MSBL, MTAL → MTBL, MALD → MBLD, MALJ → MBLJ.
Halts 40kg work pallets on a packaging conveyor using 628N of push force at 0.5 MPa, relying on the CA pivot to absorb slight misalignment during impact.
Ejects stamped metal small-parts from a die fixture, utilizing the 16mm hard-chrome plated carbon rod to withstand ejection resistance without bending.
Folds heavy cardboard flaps on a case sealer where the 55mm stroke and 528N pull force retract the mechanism quickly within tight machine clearances.
To replace the MAL40X55CA, order the MBL40X55CA and verify your CA pivot pin bore. Confirm the G1/4 port uses the default PT tapered thread. Because this SKU lacks an -S magnet, it cannot mount a sensor; if you need position detection, step up to an MBL40X55SCA and migrate from the old CS1-M/DS1-M switches to the current CMSG/DMSG/EMSG family. If you need adjustable end-cushioning to replace the fixed rubber bumper, specify the MBLC variant.
For sizing alternatives, stepping down to the 32mm bore yields 402N push at 0.5 MPa, while stepping up to the 50mm profile cylinder provides substantially higher force. Remember that a plain cylinder drifts when air is lost; the bumper softens impact but does not lock the load, so add an external rod lock for vertical holding. At 55mm stroke, side-load risk is minimal, but always ensure the CA clevis allows free articulation.
Upgrade checklist
Yes, the AirTAC MAL40X55CA is discontinued. The exact drop-in replacement is the MBL40X55CA, which matches the 40mm bore, 55mm stroke, G1/4 port, and CA pivot mount. The MBL upgrades the body to a riveted rolling-packed design while maintaining the same output force.
At 0.5 MPa, it pushes 628N and pulls 528N. At 0.7 MPa, push is 880N, with a theoretical max of 128kgf at 1.0 MPa. This specific SKU has no -S magnet, so it cannot accept position sensors. If sensors are needed, order the MBL40X55SCA and use CMSG/DMSG/EMSG switches.
