This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X175-S-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X175-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 MAL40X175-S-CM (Discontinued) → MBL40X175-S-CM is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 175mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X175-S-CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X175-S-CM is a discontinued double-acting aluminum mini round cylinder. As the largest bore in the legacy range, it delivers a robust 628 N push force at 0.5 MPa (880 N at 0.7 MPa) over a 175 mm stroke. AirTAC replaced this unit with the MBL40X175-S-CM, a drop-in alternative retaining the exact 40 mm bore, G1/4 port, M12x1.25 rod thread, and CM round-end back cover.
This SKU includes a built-in magnet (-S) for position detection. Because the original MAL uses threaded front and back covers, it differs structurally from the modern MBL replacement, which features a riveted rolling-packed body. Furthermore, the legacy CS1-M or DS1-M reed switches used here are superseded by CMSG, DMSG, or EMSG sensors on the current MBL line. The cylinder relies on a fixed rubber bumper for end-of-stroke damping, while the piston employs a heterogeneous two-way seal that retains lubricant for long service life.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X175-S-CM 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 MBL40X175-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.

Provides 628 N of push force at 0.5 MPa to eject dense plastic parts from small injection molds, utilizing the 175 mm stroke to clear the tooling entirely.
Drives a pivoting diverter arm on a packaging conveyor, where the CM round-end back cover accommodates the slight arcing motion required to route heavy cartons.
Actuates a printed circuit board test bed, using the -S magnet and CS1-M / DS1-M switches to confirm the 175 mm extension before initiating the electrical probe sequence.
To replace the MAL40X175-S-CM, order the MBL40X175-S-CM. Confirm your porting (PT tapered thread standard here), the CM round-end back cover, and prepare to upgrade your position sensing from the older CS1-M / DS1-M switches to the current CMSG / DMSG / EMSG family. If your application requires adjustable air cushioning rather than the fixed rubber bumper, step up to the MBLC40 variant on the current line. A plain cylinder cannot hold a load if air pressure drops; install an external pilot-operated check valve if drift is unacceptable.
With a 175 mm stroke, the 16 mm rod is susceptible to bending under lateral stress, so use a guided external slide to prevent side-load damage. For sizing flexibility, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, while the 40 mm remains the maximum available size in this mini round series, offering a theoretical maximum of 128 kgf at 1.0 MPa.
Upgrade checklist
Yes, the MAL series is discontinued. The exact drop-in replacement is the MBL40X175-S-CM, which matches the 40 mm bore, 175 mm stroke, G1/4 port, and CM round-end mounting. Note that the MBL uses a riveted body instead of threaded covers, and you must upgrade your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG switches.
At 0.5 MPa operating pressure, 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 theoretical maximum force is 128 kgf when operated at the 1.0 MPa pressure limit.
