This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X135U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X135U 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 MAL40X135U (Discontinued) -> MBL40X135U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 135mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X135U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X135U is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 135mm stroke. It delivers 628N push and 528N pull at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The exact drop-in replacement is the MBL40X135U, which matches the original force, port, and stroke. The legacy MAL uses a threaded front and back cover assembly, whereas the current MBL features a riveted rolling-packed body for equally robust performance.
This specific SKU features a U flat-end back cover for rigid, straight-line mounting and lacks a magnet (-S), meaning it cannot accept a position sensor. Inside, a heterogeneous two-way seal retains grease around the hard-chrome plated carbon-steel rod, supported by a self-lubricating front-cover bearing guide. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X135U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X135U 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 628N of push force at 0.5MPa to eject dense plastic parts from tight mold cavities where a larger ISO 15552 profile cylinder would not fit.
Uses the 135mm stroke to push lightweight cardboard cartons off a main conveyor belt, relying on the rigid U flat-end back cover to maintain alignment.
Holds printed circuit boards securely during automated electrical testing, utilizing the fixed rubber bumper to soften the end-of-stroke impact without marking the surface.
To replace the MAL40X135U, order the MBL40X135U. Confirm the 40mm bore, 135mm stroke, G1/4 port, and PT tapered thread are retained. This SKU has a U flat-end back cover for rigid mounting; if your application requires arcing or pivot movements, switch to the CA clevis version. Because this model lacks the -S magnet, it cannot support position sensing; if you need detection on the new unit, add -S and note that MBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M/DS1-M.
If sizing up or down, the 32mm neighbor bore provides 402N push at 0.5MPa, while there is no larger standard bore in this mini series. If your application needs adjustable end-cushioning rather than the fixed rubber bumper, specify the MBLC variant on the current line. At 135mm stroke, the 16mm rod is susceptible to bending under lateral stress; use an external guide rail to prevent side-load damage. Note that this cylinder will drift and cannot hold a load if air pressure is lost.
Upgrade checklist
Yes, the MAL40X135U is discontinued. The exact drop-in replacement is the MBL40X135U, which offers the same 40mm bore, 135mm stroke, G1/4 port, and mounting dimensions. The main difference is the MBL uses a riveted rolling-packed body instead of the threaded covers found on the MAL.
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 specific SKU lacks a magnet and cannot support position sensors.
