This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X170U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X170U 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 MAL40X170U (Discontinued) → MBL40X170U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 170mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X170U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X170U is a discontinued double-acting aluminum mini round cylinder featuring a 40mm bore and 170mm stroke. It delivers 628N push and 528N pull at 0.5MPa, utilizing a G1/4 port and a rigid U flat-end back cover. The direct drop-in replacement is the MBL40X170U, which matches the original force, stroke, and mounting dimensions exactly.
This specific SKU lacks a magnetic piston, meaning it cannot accept position sensors. The legacy MAL body uses threaded front and back covers, whereas the current MBL upgrade features a riveted rolling-packed body. Both generations rely on a fixed rubber bumper for end-of-stroke damping rather than an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X170U 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 MBL40X170U 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 the 628N push force at 0.5MPa needed to fold heavy corrugated cardboard flaps on packaging lines, with the 170mm stroke clearing tall carton webs.
Acts as a compact secondary ejector for small plastic injection molds, using its rigid U flat-end cover to mount flush against machine frames without pivot arc.
Transfers heavy bundled goods between roller conveyors in end-of-line palletizers, leveraging the 880N push force at 0.7MPa for positive product shifting.
To replace the MAL40X170U, order the MBL40X170U. Verify your setup accommodates the G1/4 port, M12x1.25 rod-end thread, and the rigid U flat-end rear cover. Because this SKU has no -S magnet, you cannot mount a sensor; if you need position detection, switch to an MBL40X170US and use the current CMSG/DMSG/EMSG switches instead of the legacy CS1-M/DS1-M. If you need adjustable air cushioning rather than a fixed rubber bumper, step up to the MBLC40X170U. For sizing flexibility, stepping down to a 32mm bore yields 402N push at 0.5MPa, while the 40mm bore provides 628N push at 0.5MPa. Note that a plain cylinder drifts when air is lost; use an external rod lock for position holding. At 170mm stroke, the 16mm rod handles moderate loads, but always guide external rods to prevent side-load bending.
Upgrade checklist
Yes, the MAL series is discontinued. The exact drop-in replacement is the MBL40X170U, which matches the 40mm bore, 170mm stroke, G1/4 port, and U flat-end cover. The MBL uses a riveted rolling-packed body instead of the older threaded covers.
The full force set is 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, with a maximum theoretical force of 128kgf at 1.0MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; you would need an S-suffix model for detection.
