This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X850-S-CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X850-S-CA 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 MAL40X850-S-CA (Discontinued) → MBL40X850-S-CA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 850mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X850-S-CA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X850-S-CA is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and an 850mm non-standard made-to-order stroke. It delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBL40X850-S-CA, matching the bore, stroke, G1/4 port, and CA pivot mounting.
This legacy unit features a built-in -S magnet for position detection with older CS1-M or DS1-M switches, whereas the modern MBL uses CMSG, DMSG, or EMSG sensors. The original MAL body uses threaded front and back covers, while the upgraded MBL utilizes a riveted rolling-packed construction. A heterogeneous two-way seal retains grease for a long service life alongside the self-lubricating front-cover bearing.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X850-S-CA 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 MBL40X850-S-CA 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 628N push force at 0.5MPa to index heavy pallets along a conveyor, relying on the CA pivot to absorb misalignment over the 850mm travel.
Swings a heavy routing flap on a packaging line, where the G1/4 port provides sufficient airflow to maintain a 30-800mm/s speed range across the long stroke.
Lifts corrugated cartons between conveyor tiers, requiring the -S magnet and CS1-M switches to confirm top and bottom positions over the 850mm extension.
To replace this discontinued cylinder, order the MBL40X850-S-CA. Confirm the 40mm bore, 850mm stroke, M12x1.25 rod thread, PT port thread, and the CA pivot back cover. If you need to downsize, the 32mm bore provides 402N push at 0.5MPa; if you need more power, note that 40mm is the largest MAL bore available. Because the 850mm stroke exceeds the 500mm standard, it is a special-order item.
At 850mm, the Ø16mm carbon-steel rod is highly susceptible to bending under side loads—use the CA clevis to allow articulation or add an external guide rail. The fixed rubber bumper softens end-of-stroke impacts but is not an adjustable air cushion; for that, step up to the current MBLC line. A plain cylinder drifts when air is lost, so add a rod lock for suspended loads.
Upgrade checklist
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL40X850-S-CA. It matches the 40mm bore, 850mm stroke, CA pivot mounting, G1/4 port, and force ratings. You must upgrade your position sensors, as the older CS1-M and DS1-M switches are replaced by CMSG, DMSG, or EMSG models on the MBL.
At 0.5MPa, the push force is 628N and the pull force is 528N. At 0.7MPa, the push force increases to 880N. The maximum theoretical force is 128kgf at 1.0MPa. Note that this 850mm stroke is a non-standard made-to-order length exceeding the 500mm standard maximum.
