This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X175-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X175-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 MAL40X175-S-U (Discontinued) -> MBL40X175-S-U 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-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X175-S-U is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces. Delivering 628 N push and 528 N pull force at 0.5 MPa (880 N push at 0.7 MPa), it features a 40 mm bore, a 175 mm stroke, and a G1/4 port. The exact drop-in replacement is the MBL40X175-S-U, which matches the original bore, stroke, output force, port size, and U flat-end mounting.
This legacy SKU includes a built-in magnet (-S) for position sensing, originally paired with CS1-M or DS1-M switches; upgrading to the MBL requires switching to current CMSG, DMSG, or EMSG sensors. The MAL utilizes a carbon-steel rod with 20 um hard chrome plating and a heterogeneous two-way grease-retaining seal. Unlike the threaded front and back covers on the MAL, the modern MBL features a riveted rolling-packed body for equivalent structural integrity.

The MBL40X175-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.

Folds corrugated cardboard flaps on a packaging line using 628 N of push force at 0.5 MPa, fitting neatly into tight conveyor side-frames.
Acts as a compact 175 mm stroke gate to meter steel bar stock into a CNC lathe, benefiting from the 16 mm hard-chrome plated rod for wear resistance.
Pushes lightweight totes onto a secondary packaging roller track, leveraging the rigid U flat-end back cover for stable rear mounting against machine framing.
To replace the MAL40X175-S-U, order the MBL40X175-S-U. Verify your 40 mm bore, 175 mm stroke, G1/4 port, and PT tapered thread form. The U flat-end back cover provides a rigid rear mounting surface. Because this SKU includes the -S magnet, plan to upgrade your CS1-M or DS1-M sensors to the CMSG, DMSG, or EMSG family used on the MBL. The MAL relies on a fixed rubber bumper; if your application requires adjustable end-of-stroke cushioning, step up to the current MBLC variant. If you need to adjust force, the next size down is the 32 mm bore (402 N push @0.5 MPa), and the next size up requires a different cylinder family entirely, as 40 mm is the largest MAL/MBL mini round bore. At 175 mm stroke, side-load tolerance is moderate; use an external guide to prevent rod bending. A plain MBL does not hold a load when air is lost, so add a rod lock or pilot-operated check valve for fail-safe positioning.
Upgrade checklist
Yes, the MAL40X175-S-U is discontinued. The exact drop-in replacement is the MBL40X175-S-U, offering the same 40 mm bore, 175 mm stroke, 628 N push force at 0.5 MPa, G1/4 port, and U flat-end mounting. You will need to update your position sensors from the legacy CS1-M/DS1-M to the modern CMSG/DMSG/EMSG family.
The MAL40X175-S-U operates at 0.1-1.0 MPa. At 0.5 MPa it provides 628 N push and 528 N pull force. At 0.7 MPa the push force is 880 N. The theoretical maximum force is 128 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion.
