This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X150-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X150-S-U 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 MAL40X150-S-U (Discontinued) → MBL40X150-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 150mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X150-S-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X150-S-U is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces requiring substantial thrust. Delivering 628 N of push force at 0.5 MPa and 880 N at 0.7 MPa, it utilizes a 16 mm carbon-steel rod with 20 um hard chrome plating. The exact drop-in replacement is the MBL40X150-S-U, matching the 150 mm stroke, G1/4 port, and U flat-end back cover perfectly.
A key upgrade detail is the body construction: the legacy MAL features threaded front and back covers, whereas the current MBL utilizes a riveted rolling-packed body. Because this SKU includes the -S magnet, it originally paired with CS1-M and DS1-M reed switches; the MBL successor transitions to the modern CMSG, DMSG, and EMSG sensor families. The piston relies on a heterogeneous two-way seal that retains grease, while the self-lubricating front-cover bearing guide ensures smooth operation across the 30-800 mm/s speed range.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X150-S-U 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 MBL40X150-S-U 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 dense plastic parts from tight mold cavities, leveraging the 16 mm hard-chrome rod for wear resistance.
Uses the 150 mm stroke to extend a diverter arm on a packaging line, with the U flat-end cover providing rigid alignment against side shear.
Drives a folding blade to close heavy corrugated carton flaps, relying on the 880 N push at 0.7 MPa to overcome board stiffness in compact spaces.
To replace the MAL40X150-S-U, order the MBL40X150-S-U and verify your 40 mm bore, 150 mm stroke, G1/4 port, and PT tapered thread. Confirm the U flat-end back cover for rigid mounting and the -S magnet requirement, noting the sensor shift to CMSG/DMSG/EMSG switches. If your application needs adjustable end-cushioning to mitigate impact, step up to the MBLC variant, as the MAL only offers a fixed rubber bumper.
For sizing flexibility, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, while stepping up is unavailable as 40 mm is the maximum bore for this mini series. At 150 mm stroke, side-load tolerance is a concern due to the 16 mm rod; use an external guide or pivot to prevent rod bending. A plain MBL does not hold its load when air is lost—the bumper only softens end-of-stroke impact, so add a rod lock for suspended loads.
Upgrade checklist
Yes, the MAL40X150-S-U is discontinued. The exact drop-in replacement is the MBL40X150-S-U, offering the same 40 mm bore, 150 mm stroke, 628 N push force at 0.5 MPa, G1/4 port, and U flat-end mounting. You also gain the modern riveted body design.
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 of 128 kgf at 1.0 MPa. Because it has the -S magnet, it works with older CS1-M and DS1-M switches; the MBL replacement requires CMSG, DMSG, or EMSG sensors.
