This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X270CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X270CM 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 MAL40X270CM (Discontinued) → MBL40X270CM is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 270mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X270CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X270CM is a discontinued double-acting aluminum mini round cylinder. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa, utilizing a 16 mm carbon-steel rod with 20 um hard-chrome plating. AirTAC replaced this legacy unit with the MBL40X270CM, a drop-in alternative retaining the exact 40 mm bore, 270 mm stroke, G1/4 port, and CM round-end back cover.
This specific SKU lacks a -S magnet, so it cannot support position sensing out of the box. Furthermore, the original MAL features a heterogeneous two-way grease-retaining seal and a self-lubricating front-cover bearing guide. The modern MBL upgrade transitions from the older threaded front and back covers to a riveted rolling-packed body while maintaining identical operational ratings.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X270CM 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 MBL40X270CM 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.

Uses the 628 N push force at 0.5 MPa to deflect medium-weight cardboard boxes on a packaging conveyor, with the 270 mm stroke providing ample reach across the belt.
Actuates a pivoting clamp arm on a CNC machining fixture, relying on the CM round-end back cover to accommodate slight arcing during the clamping motion.
Pushes plastic injection-molded components out of a tooling cavity, where the fixed rubber bumper absorbs the impact at the end of the 270 mm extension.
To replace the MAL40X270CM, order the MBL40X270CM. Confirm the 270 mm stroke, G1/4 port, and PT tapered thread form match your manifold. Because this SKU has no -S magnet, it cannot accept a sensor; if you need position detection, select an MBL40X270CMS and note that the modern MBL uses CMSG, DMSG, or EMSG switches rather than the legacy CS1-M or DS1-M. The fixed rubber bumper softens end-of-stroke impacts, but for adjustable air cushioning, you must step up to the current MBLC line.
If you are sizing this actuator, the 32 mm neighbor bore provides 402 N of push force at 0.5 MPa, while the 40 mm bore yields 628 N. Stepping up is not possible within the MAL mini range, as 40 mm is the largest available bore. Since the 270 mm stroke exceeds 300 mm, the 16 mm rod has limited side-load tolerance; use an external guide rail or a pivot mount to prevent rod bending. Note that a plain cylinder drifts when air is lost—the bumper is not a locking mechanism.
Upgrade checklist
Yes, the MAL40X270CM is discontinued. The exact drop-in replacement is the MBL40X270CM, which matches the 40 mm bore, 270 mm stroke, G1/4 port, and CM round-end mounting. The MBL uses a riveted body instead of threaded covers, but the performance and dimensions remain identical.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. Because this specific SKU lacks a -S magnet, it cannot accept position sensors.
