This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X20CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X20CA 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 MAL40X20CA (Discontinued) → MBL40X20CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 20mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X20CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X20CA is a discontinued double-acting aluminum mini round cylinder built for compact, high-force actuation. Delivering 628 N of push force at 0.5 MPa and 880 N at 0.7 MPa, it uses a 16 mm carbon-steel rod with 20 um hard-chrome plating guided by a self-lubricating front-cover bearing. Because this legacy series is end-of-life, AirTAC replaced it with the MBL40X20CA—a drop-in alternative retaining the exact 40 mm bore, 20 mm stroke, G1/4 port, and CA pivot mounting.
This specific SKU features a CA pivot back cover, designed to swing on a pin to absorb arcing rod paths and side-play. Two engineering details define this generation: the MAL body uses threaded front and back covers, whereas the current MBL upgrade features a riveted rolling-packed body for faster assembly. Furthermore, this configuration lacks a built-in magnet (-S), meaning it cannot accept a position sensor; if you ever need sensing on the MBL replacement, you must order an -S version and migrate to the modern CMSG, DMSG, or EMSG switch families, as the older CS1-M and DS1-M sensors are phased out.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X20CA 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 MBL40X20CA 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.

Provides 628 N of push at 0.5 MPa to knock out small plastic parts from tight mold cavities where a full-size cylinder would not fit.
Swings a lightweight sorting flap on a packaging line using the CA pivot back cover, handling arcing motion without binding the 16 mm rod.
Trips a heavy mechanical latch on an end-of-line pallet dispenser, using the 128 kgf maximum theoretical force to overcome sticky spring plungers.
To replace the MAL40X20CA, order the MBL40X20CA to match the 40 mm bore, 20 mm stroke, PT port thread, and CA pivot back cover exactly. If you need to step down to a smaller bore, the 32 mm neighbor provides 402 N of push force at 0.5 MPa; if you need more force, note that 40 mm is the largest standard MAL mini round bore, so stepping up requires moving to a different cylinder family entirely. Because this is a short 20 mm stroke, side-load bending is minimal, but the CA pivot is still essential if your linkage arcs.
Keep in mind that the fixed rubber bumper on this cylinder softens the end-of-stroke impact but is not an adjustable air cushion—if you need precise end-of-stroke deceleration, step up to the current MBLC variant. Additionally, a plain MAL or MBL does not hold its position or load when air is lost—the rod drifts. For a held load, install an external rod lock or a pilot-operated check valve. Finally, since this specific SKU has no -S magnet, you cannot mount a sensor to it; order the MBL40X20CAS if position detection is required.
Upgrade checklist
Yes, the MAL40X20CA is discontinued. The exact drop-in replacement is the AirTAC MBL40X20CA, which matches the 40 mm bore, 20 mm stroke, 628 N push force at 0.5 MPa, G1/4 port, and CA pivot mounting. The main upgrade is that the MBL uses a riveted rolling-packed body instead of the older threaded covers.
The 40 mm bore generates 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; if you need sensing on the MBL replacement, you must order an -S version and use CMSG, DMSG, or EMSG switches.
