This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X55CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X55CM 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 MAL40X55CM (Discontinued) → MBL40X55CM 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 MBL40X55CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X55CM is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 55mm stroke. It delivers 628N of push force at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The exact drop-in replacement is the MBL40X55CM, which matches the bore, stroke, output force, port size, and mounting accessories for a seamless upgrade.
This legacy SKU includes a CM round-end back cover and lacks a built-in magnet, meaning it cannot support any position sensing. Unlike the older MAL body that used threaded front and back covers, the modern MBL replacement features a riveted rolling-packed body for greater structural integrity. Both iterations rely on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X55CM carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X55CM 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.

| 40 | Bore size in mm (20/25/32/40). |
| ×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.
Provides 628N of push force at 0.5MPa to eject small plastic parts from tight mold cavities where a compact 40mm bore is required.
Uses the 55mm stroke to actuate a routing flap on a packaging conveyor, relying on the CM round-end cover to accommodate slight angular misalignment.
Drives a mechanical folder arm to tuck minor flaps on packing lines, using its 880N push force at 0.7MPa to overcome cardboard stiffness.
To replace the MAL40X55CM, order the MBL40X55CM and verify your 40mm bore, 55mm stroke, G1/4 port, and CM round-end back cover. Because this specific legacy unit has no -S magnet, it cannot accept a position sensor; if you need end-of-stroke detection, you must upgrade to an MBL40X55CMS and switch to the current CMSG, DMSG, or EMSG switch family, as the older CS1-M/DS1-M sensors are obsolete. If you need to adjust your force output, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up is not possible as 40mm is the largest standard MAL mini round size. Note that the fixed rubber bumper cannot be adjusted; for adjustable air cushioning, specify the MBLC40 series on the current line. Keep in mind that a plain cylinder does not hold its position or load when air is lost, as the rod will drift.
Upgrade checklist
Yes, the MAL40X55CM is discontinued. The exact drop-in replacement is the MBL40X55CM, which offers the same 40mm bore, 55mm stroke, 628N push force at 0.5MPa, G1/4 port, and CM round-end back cover. The MBL features a riveted rolling-packed body instead of the older threaded covers.
At 0.5MPa, it delivers 628N push and 528N pull force; at 0.7MPa, push increases to 880N, with a theoretical maximum of 128kgf at 1.0MPa. Because this specific SKU lacks an -S magnet, it cannot accept any position sensor; detection requires upgrading to an MBL40X55CMS with a CMSG, DMSG, or EMSG switch.
