This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X450-S-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X450-S-CM 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 MAL40X450-S-CM (Discontinued) → MBL40X450-S-CM is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 450mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X450-S-CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X450-S-CM is a discontinued double-acting aluminum mini round cylinder built for compact spaces. It delivers a robust 628 N push and 528 N pull at 0.5 MPa, utilizing a 16 mm carbon-steel rod with 20 um hard chrome plating to handle heavy loads. AirTAC replaced this legacy unit with the MBL40X450-S-CM, a drop-in alternative retaining the exact 40 mm bore, 450 mm stroke, G1/4 port, and CM round-end back cover.
This specific SKU includes a built-in magnet for position detection. A key upgrade detail is that the original MAL threaded front and back covers transition to a riveted rolling-packed body on the MBL. Furthermore, the older CS1-M and DS1-M reed switches used on this MAL -S model are superseded by the modern CMSG, DMSG, and EMSG sensor families on the MBL replacement.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X450-S-CM 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 MBL40X450-S-CM 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.
Actuates a heavy diverter gate on a packaging conveyor, using the 628 N push force at 0.5 MPa to reliably redirect 40 kg product pallets.
Secures aluminum engine blocks during CNC machining, leveraging the 450 mm stroke to reach across a wide fixture bed and the CM round-end cover for slight pivot alignment.
Lifts stacked cardboard cartons between floor levels, depending on the 880 N push force at 0.7 MPa to overcome gravity on the upward stroke.
To replace the MAL40X450-S-CM, order the MBL40X450-S-CM. Confirm your 40 mm bore, 450 mm stroke, M12x1.25 rod thread, and the CM round-end back cover. The default PT tapered port threads remain identical. Because this SKU has the -S magnet, you must upgrade your sensors from the legacy CS1-M or DS1-M to the current CMSG, DMSG, or EMSG switches. If you need a smaller bore, the 32 mm neighbor provides 402 N push at 0.5 MPa; stepping up is not possible as 40 mm is the largest in this mini series.
With a 450 mm stroke, the 16 mm rod is highly susceptible to bending under side loads, so an external guide rail or a pivot mount is required to prevent premature seal wear. The MAL uses a fixed rubber bumper, not an adjustable cushion; if end-of-stroke shock is an issue, step up to the current MBLC series for an adjustable air cushion. Note that this cylinder will drift and cannot hold a load if air pressure is lost, so fit an external rod lock for vertical applications.
Upgrade checklist
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL40X450-S-CM, which matches the 40 mm bore, 450 mm stroke, G1/4 port, 128 kgf max force, and CM mounting. You must swap the old CS1-M or DS1-M sensors for CMSG, DMSG, or EMSG switches.
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa the push force is 880 N, with a theoretical maximum of 128 kgf at 1.0 MPa. It operates on filtered air at 0.1-1.0 MPa, runs at 30-800 mm/s, and uses a fixed rubber bumper rather than an adjustable cushion.
