This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X900-S-CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X900-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 MAL40X900-S-CM (Discontinued) -> MBL40X900-S-CM is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 900mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X900-S-CM, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X900-S-CM is a discontinued double-acting aluminum mini round cylinder engineered for a 900 mm non-standard stroke. Delivering 628 N of push force at 0.5 MPa, it features a built-in magnet (-S) for position sensing and a CM round-end back cover. AirTAC ended the MAL line, replacing it with the MBL40X900-S-CM—a drop-in alternative retaining the exact 40 mm bore, stroke, G1/4 port, and 128 kgf maximum force.
This legacy unit relies on a threaded front and back cover assembly, whereas the current MBL utilizes a riveted rolling-packed body for equivalent durability. The -S magnet on this MAL interfaces with older CS1-M or DS1-M reed switches; upgrading to the MBL requires migrating to modern CMSG, DMSG, or EMSG sensors. A fixed rubber bumper absorbs end-of-stroke impact, though buyers needing adjustable air cushioning must step up to the MBLC variant.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X900-S-CM carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X900-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.

Uses the 880 N push force at 0.7 MPa to deflect heavy pallets onto secondary packaging lines over the extended 900 mm travel distance.
Pushes raw metal bar stock through the spindle, relying on the 40 mm bore and CM round-end cover to accommodate long-axis alignment variations.
Raises multi-tier storage rack gates, where the 900 mm stroke provides the necessary vertical clearance and the fixed bumper cushions the top stop.
To replace the MAL40X900-S-CM, order the MBL40X900-S-CM. Verify your 16 mm rod-end thread (M12x1.25), the default PT tapered port threads, and the CM round-end back cover. Because this 900 mm stroke exceeds the 500 mm standard maximum, it is a made-to-order component. If your application requires less force, step down to the 32 mm bore (402 N push at 0.5 MPa); if you need more power, note that 40 mm is the largest available mini round body in this family.
At 900 mm, the 16 mm carbon-steel rod is highly susceptible to bending under side loads—utilize an external guide rail to prevent premature seal wear. The fixed rubber bumper softens impact but will not hold a load if air pressure drops; install a pilot-operated check valve for position holding. When migrating the -S magnet, plan to replace legacy CS1-M sensors with CMSG switches.
Upgrade checklist
Yes, the MAL40X900-S-CM is discontinued. The exact drop-in replacement is the MBL40X900-S-CM, which matches the 40 mm bore, 900 mm stroke, G1/4 port, and CM mounting. Note that the MBL uses a riveted body instead of threaded covers, and you must upgrade your CS1-M sensors to the CMSG family.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 880 N, with a theoretical maximum of 128 kgf at 1.0 MPa. The standard stroke maxes out at 500 mm, so this 900 mm configuration is a non-standard, made-to-order part.
