This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X45SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X45SU 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 MAL40X45SU (Discontinued) → MBL40X45SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 45mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X45SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X45SU is a discontinued double-acting aluminum mini round cylinder. As the largest bore in the MAL family, it delivers a robust 628 N push force at 0.5 MPa, utilizing a 16 mm carbon-steel rod with 20 um hard-chrome plating. The exact drop-in replacement is the MBL40X45SU, which matches the original 40 mm bore, 45 mm stroke, G1/4 port, and U flat-end rear cover.
This specific SKU includes a built-in magnet (-S) for position detection. Because it is a legacy MAL cylinder, the magnet interfaces with the older CS1-M and DS1-M reed switches. When upgrading to the MBL40X45SU, you must also migrate to the current CMSG, DMSG, or EMSG sensor family. Additionally, the original threaded front and back covers are replaced by a riveted rolling-packed body on the MBL, maintaining identical pressure ratings while modernizing the assembly.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X45SU 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 MBL40X45SU 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.
Provides 628 N of push force at 0.5 MPa to eject small plastic parts from tight mold cavities where a compact 40 mm bore is required.
Uses the 45 mm stroke to rapidly actuate a diverting gate on a packaging line, relying on the G1/4 port for high flow to maintain 30-800 mm/s speeds.
Cycles double-acting to fold heavy cardboard flaps during case sealing, utilizing the rigid U flat-end cover to mount firmly to the machine frame.
To replace the MAL40X45SU, order the MBL40X45SU. Confirm your 40 mm bore, 45 mm stroke, G1/4 port, PT tapered thread, and the rigid U flat-end back cover. Because this SKU features the -S magnet, plan to swap your existing CS1-M or DS1-M switches for CMSG, DMSG, or EMSG sensors to fit the MBL body. If your application requires an adjustable air cushion rather than the fixed rubber bumper found on the MAL, step up to the MBLC variant on the current line.
When sizing this actuator, you can step down to the 32 mm bore if you need less force (it provides 402 N push at 0.5 MPa), or look outside the MAL/MBL mini round family if you need more than the 628 N this 40 mm bore provides. Remember that a plain double-acting cylinder does not hold its load if air pressure drops; the bumper only softens the end of stroke. Install an external rod lock or pilot-operated check valve if the U flat-end mounted load must remain secure during an air loss event.
Upgrade checklist
Yes, the MAL40X45SU is discontinued. The exact drop-in replacement is the MBL40X45SU, offering the same 40 mm bore, 45 mm stroke, 628 N push force at 0.5 MPa, G1/4 port, and U flat-end mounting. You simply order the MBL equivalent.
At 0.5 MPa, the push force is 628 N and pull is 528 N. At 0.7 MPa, push is 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa. The -S magnet works with older CS1-M and DS1-M switches; upgrading to the MBL requires CMSG, DMSG, or EMSG sensors.
